Release History

===============

This is an overview of the changes that were incorporated into past releases.

openMSX 21.0 (2025-09-26)

-------------------------

This release has many improvements on the new GUI introduced in openMSX 20.0

(especially the debugger) and several other smaller features. It also

introduces the "setups" concept, which enables you to define an MSX setup (e.g.

a Philips VG 8020 with an external disk drive and a joystick, data recorder and

printer connected). These can be created, loaded, and automatically started.

They can also be saved automatically when you exit.

Furthermore, flash chip emulation has become a lot more accurate, thanks to

Laurens Holst.

Special thanks to all the contributors of this release who are not in the core

team! Keep those pull requests coming!

  fine in terms of speed on contemporary hardware

- removed OSD based raster beam viewer (use the bitmap/character viewer

  instead)

openMSX 20.0 (2024-09-22)

-------------------------

This is a major release, in which we introduce the new Graphical User

Interface, replacing the OSD menu. A faster and more powerful debugger is now

included in openMSX itself. Configuration for MSX joystick/JoyMega has been

improved drastically using the new GUI.

As of now, a system with OpenGL 2 support is required to run openMSX.

The GUI

^^^^^^^

We already had two separate GUI applications:

- openMSX Catapult, a tool to control common functionality of openMSX, in a

  limited way.

- openMSX Debugger, a great and helpful tool, but never officially released and

  packaged.

Keeping the GUI separate from the emulation core seemed like a good idea at

first. Keeping the state of both applications in sync turned out to be a hard

problem, however. Functions that seemed easy, were in fact very hard to

implement in this structure.

In this release we integrated the GUI directly in openMSX itself. All

information is now guaranteed in sync and updated real-time (which would have

been very hard in the old structure).

As this is the first release with the new GUI, not everything will be perfect

straight away. Feedback or help to improve things further will be highly

appreciated. The Catapult and openMSX Debugger applications remain available

for the time being. We will (try to) keep them working, but they won't receive

any new development anymore - from us anyway. When keeping them working becomes

too much of a burden, we will abandon these applications altogether.

Joystick emulation

^^^^^^^^^^^^^^^^^^

Another big change is the joystick emulation. There are now fixed joystick and

JoyMega (MegaDrive controller) pluggables (2 for each), which can also be

configured via the GUI and also support keyboard inputs, so they also replace

the old keyjoystick devices. This gives optimal flexibility for configuring how

you want to control MSX controllers.

On top of that, it is now possible to plug and unplug host controllers at

run-time.

Rendering

^^^^^^^^^

Rendering has also undergone a big change. We removed the "SDL" renderer, as

the GUI requires an accelerated backend, for which we use OpenGL 2, which was

already required for the (already default and now only) SDLGL-PP renderer.

We also removed 1x scaling, so the minimum is now 2x. Video recording and

screenshots on the 320x240 resolution are still possible, though. All of this

allowed us to simplify the code a lot, making it easier to add new features and

maintain the code.

Other important changes

^^^^^^^^^^^^^^^^^^^^^^^

As for any custom key bindings you might have: we renamed some keys to match the SDL

library names instead of inventing our own. Old names are still recognized, but

be careful if you also run older openMSX versions, as openMSX will use the new

names and the old openMSX will not recognize them. Examples are: PRINT ->

PrintScreen, META -> GUI.

MSX device support:

- V99x8:

  - fixed ugly looking top line when displaying interlacing

  - fixed rounding for 'blue' in YJK modes

- Use cleaned up disk ROMs in several configurations (without registers)

- Fixed several configs that had wrongly a memory mapper: Sony HB-F1XD,

  HB-F1XDmk2, Panasonic FS-A1mk2

  mapping tables, which were released as part of Unicode) and other keyboard

  fixes/improvements (e.g. a French/Arabic unicodemap)

- Added MSX character to unicode (and vice versa) mapping, which is used in the

  get_screen script

- Fixed several bugs in save_msx_screen script (as seen in Yupipati)

  - added menu option to change host to MSX joystick mapping

- Added script that can show where the raster beam is on the screen

- Added script that shows sprite locations and information on the OSD

- Also display hours in the reverse bar

- Fixed crash when using "record_channels cassetteplayer" with resampler=blip

- Don't remove once-breakpoints if condition fails

- Added internal events on breakpoint/watchpoint/condition/probe add/remove

  (unused so far, but may help debugger development)

- Allow multiple errors/warnings to be displayed on OSD

- Large update of the ROM database

Build system, packaging, documentation:

- C++ code is based on C++20 and thus requires a compiler supporting it, e.g.

  g++ 9 or later (10 is recommended and will be necessary for the next release)

  or Visual Studio 2022 or later

- Updated catch2 to 2.13.7

team! Keep these pull requests coming!

Here's the list with all highlights and details:

MSX device support:

- V99x8:

    Psycho World, Hydefos, Space Manbow and the Woei demo, and probably more.

    Many thanks to Grauw for figuring out the real problem.

  - fixed that sprites are not disabled instantly, but on the next line

- Carnivore 2:

  - updated initial (out-of-the-box) flash content, with bootmenu 2.40

  - Arjen Zeilemaker and others: Toshiba HX-33 and HX-34 (except for the COPY

    button and special hardware for that)

  - Danilo Angel: Sanyo MPC-3

  - others: Sony HB-75D, Sanyo PHC-28P

- added new extensions: Popolon Sound Cartridge (with configurable size)

New or improved emulator features:

- by default also map the D-pad of a controller to the MSX joystick directions

- fixed artifacts on 3x scaling with 512 wide MSX modes on SDLGL-PP

- optimized file pool more, especially when alternative ROMs are to be found

- more accurate resampling, without rounding errors

- added support for autoruncassettes for SVI CAS files

- fixed autoruncassettes on some models like Yamaha AX150

- OSD menu:

  - menu button is now easy to disable with new osd_menu_button setting

  - removed useless frameskip controls

  - added full speed when loading control

  - tweaked special options in lists like [eject]

  - fixed navigating to file pools for disks

    openMSX

  - allow searching also on _ and - characters in lists

  - show display names of what is in a media slot

  - show ROM info of just inserted ROM, not of the most likely running ROM

  - show also MSX slot number in list of cartridge slots

  - fixed handling of multiple identical extensions

- SDLGL-PP renderer requirements are now relaxed to only OpenGL 2.1 again (was

  3.3 in openMSX 16.0)

- fixed building without SDL joystick support

- C++ code is based on C++17 and thus requires a compiler supporting it, e.g.

  g++ 8 or later or Visual Studio 2019 or later

- 3rd party updates of Tcl (8.6.10) and libpng (1.6.37)

openMSX 16.0 (2020-08-25)

-------------------------

A major release in which we finally migrated to SDL2 and Tcl 8.6. And we moved

to a simpler versioning scheme, stripping off that 0. prefix now :) Other than

that, there are loads and loads of improvements. Some often requested ones are

copy/paste functionality and drag and drop support. But we also added a super

accurate YM2413 emulation (originally written by NukeYKT), fixed MIDI-in/out

support on Windows, a new keyboard mode, much improved OSD menu, etc. See below

for the details.

Special thanks to all the contributors of this release who are not in the core

team! Keep these pull requests coming!

Here's the list with all highlights and details:

MSX device support:

- V9990:

  - added EOR feature in V9990 bitmap cursor rendering

  - fixed crash in overscan modes with deflicker filter

  - fixed YJK/YUV rendering (was broken 8 years ago...)

  - fixed BMLX command

  - fixed drawing of second cursor (in some cases)

  - added synchronization for the CE IRQ

  - fixed sprite rendering algorithm on P modes

  - fixed background rendering in P2

  - fixed crash when using V9990 B4 mode with SDL renderer and scale_factor 3

- V99x8:

  - fixed that set adjust has no influence on maximum horizontal interrupt line

  - fixed right border on V9958 horizontal scroll

  - implemented "Cadari" bit

  - fixed sprite collision detection with color 0 sprites

  - fixed behaviour of TP bit in sprite mode 1

- PSG:

  - fixed that PSG registers of turboR do not mirror

  - fixed behaviour of wrong PSG port configuration (input ports output 0xFF)

  - it is now possible to specify whether a machine ignores PSG port

    directions; this helps to only show the warning on machines that may

    actually get damaged by these PSG bits

  - fixed noise level 0 ("sound6,0")

- fixed behaviour details of ADPCM of MSX-AUDIO

- fixed VDP I/O wait cycles of T9769: only apply to Z80

- fixed initial RAM pattern of ColecoVision to 0x00, which fixes The Heist

- fixed register mirroring of Yamaha SFG modules

- improved loading bad quality WAV cassette images using cubic interpolation

- added very accurate (but also slower) NukeYKT YM2413 core (now also the

  default)

- added emulation of 256kB hangul font ROM of the Daewoo CPC-400S

- added emulation of mappers Repro Cartridge mapper (v1 and v2) and Matra

  Compilation (e.g. Konami Compilation 1 and 2)

- fixed keyboard type of CIEL Expert Turbo

- fixed RAM size of Daewoo DPC-180

- added mapper type for RBSC Flash cartridges with KonamiSCC mapper

- added new machines: Yamaha AX500 (thanks Hashem Khalifa), Toshiba HX-20E

  (thanks Isaac Santaolalla), Yamaha YIS-503, YIS-503II, CX5F, YIS-604/128,

  Sony HB-G900D (thanks Peter Hanraets), Yamaha AX150 (thanks Pedro Gimeno),

  Olympia PHC-2 (thanks Patrick)

- added new extensions: Yamaha FD-03 (thanks Arjen) and FD-05 disk drive,

  Toshiba HX-F101PE disk drive, ROM Hunter Mk2 (thanks BiFi, Takamichi), Sony

  HBI-J1 (thanks Sandy), JVC MSX MIDI (thanks gflores)

New or improved emulator features:

- F11 now toggles fullscreen mode on PC, to be consistent with other

  applications such as web browsers; mute is now under F12

- fixed crash in ColecoVision when e.g. ALT+SPACE was pressed

- fixed crash when ejecting tape during cassette loading

- fixed MIDI-in/out support on Windows

- fixed possible crashes when using reverse

- added drag and drop support of files on the openMSX window. Supports ROM

  files, disk images (and folders), cassette images, LaserDisc images,

  savestates, replays, text files, Tcl scripts.

- added copy/paste functionality: with CTRL+Win+V (Cmd+V on Mac) or the middle

  mouse button, the clipboard text will be pasted into the MSX and with

  CTRL+Win+C (Cmd+C on Mac), the current MSX text screen will be copied to the

  clipboard

- added paste functionality to the console (CTRL+V/Cmd+V on Mac)

- several other small console improvements:

  - for macOS: Home/End moves to top/end of history, Cmd+Left/Right moves

    cursor to start/end of the line

  - move cursor per word with Alt+Left/Right

  - clear console with Ctrl+L and Cmd+K on macOS

  - Alt+BackSpace: delete backwards up to the start of the word

  - Alt+D (Alt+Del on macOS): delete util the end of the word

- added new POSITIONAL keyboard mapping mode, which is a much improved version

  of the KEY mode. Use when CHARACTER mode isn't working properly for you

- added file extensions to OSD menu and command line (e.g.

  .fd1/.fd2/.fd?/.1/.2)

- OSD menu:

  - when browsing for a media (ROM, disk, etc.) the menu now starts with the

    currently selected item. Makes it much easier to set disk B of a game, for

    instance.

  - implemented quick search in lists with alphanumeric keys. Type the name you

    expect and the cursor will find items starting with the typed characters.

  - fixed filtering out symlinked configurations from the machine/extension

    lists

  - go to the top of a list with HOME or CTRL+LEFT. Go to the end by pressing

    UP after that, as the lists wrap around :)

  - now all cartridge slots and disk drives can be controlled from OSD

  - show on/off instead of true/false for boolean settings

  - added keyboard mapping mode setting to OSD menu

- added setting to control vsync. Default is now enabled

- added new settings 'fastforward' and 'fastforwardspeed' to offer a way to go

  fast for a while (e.g. with the F9 button, which has now its binding changed

  to this) without going insanely fast.

- With vsync enabled the maxframeskip will not have to be tweaked anymore to go

  faster than the host monitor frame rate. Fast forward just works as you would

  expect it

- added new OSD icon set, which positions icons as far to the bottom as

  possible (set3)

- use soft-fullscreen now, instead of changing display modes. This looks better

  on almost all modern monitors. As a consequence, a screenshot made on full

  screen will be larger and will probably show letter boxes at the sides.

- huge updates to the Software DB:

  - many fixes

  - countless new entries for many ROM files you can find on the web

- when using IPS patches, the patched ROM will be looked up in the Software DB

- support host system function keys up to F24 now

- improved error messages on console commands (e.g. wrong number of arguments,

  unknown options, wrong subcommands)

- fixed cursor grabbing when going to and coming back from fullscreen

- enable HighDPI support (at least fixes some issues on macOS)

- fixed (removed) influence of user pressing modifier keys (CTRL/SHIFT/...)

  when text is typed into the MSX (e.g. with type command, auto cassette run,

  text pasting)

- added -once flag to 'debug set_bp' (and related commands) to trigger once

- several fixes to the unicode map files, so that pasting and CHARACTER

  keyboard mode works better (especially on Spanish MSX machines)

- added a debug probe on the V99x8 command execution and with that made the

  vdp_busy script more accurate

- worked around bug/limitation of MSX-BIOS when typing MSX characters 00-1F,

  which now works reliably

- fixed crash when using a relative path with the -setting command line option

- fixed 'kbd_code_kana_host_key' setting (did (sometimes?) not work anymore)

- use Rebecca Bettencourt's officially proposed Unicode mapping of MSX character

  set

- save_msx_screen script now also supports interlaced images

- added '-command' command line option to execute the given command after

  starting

- disable V99x8 specific debug writes on MSX1 VDP's

- added an optional <exit-code>-parameter to the exit command

- added script and MSX-DOS tool to give openMSX commands from within the

  emulated MSX (which is not enabled by default)

- when recording to video with throttle off, save time by displaying as few

  frames as possible on the screen

- now remember window position when the window is recreated (e.g. when changing

  renderers or coming back from full screen)

- make it easier to handle non-specific input events in Tcl scripts

- WARNING: backwards incompatible change to the 'machine_info device <device>'

  command. The result for ROM devices is now a dict (instead of a list) with at

  least one key-value pair, with key "type". For certain devices more key-value

  pairs are present, that were previously in list elements 1 to 3. Example to

  get the mapper type of device 'usas':

  dict get [machine_info device usas] "mappertype"

  And to get the device type (works for any device) of MyCoolDevice:

  dict get [machine_info device MyCoolDevice] "type"

Build system, packaging, documentation:

- migrated to SDL2 (2.0.12)

- unfortunately, the Android port is for now broken, as we did not integrate it

  into our build system yet (and that's not easy). The C++ code does compile,

  and now requires NDK20 and API level 18 (Android 4.3)

- updated all other 3rdparty libraries as well, like upgrading to Tcl 8.6

- SDLGL-PP renderer now requires OpenGL 3.3, shaders are now in GLSL 3.30

- support for pkg-config in the build system, e.g. to build FreeType

- C++ code is based on C++17 and thus requires a compiler supporting it, e.g.

  g++ 7 or later or Visual Studio 2019 or later

- fixed endianness on ppc64le

- fixed compilation for big-endian CPUs with g++-9

- migrated build system and all other Python scripts to Python 3, as Python 2

  is now officially dead

- documentation is now in HTML5 instead of XHTML

openMSX 0.15.0 (2018-12-08)

---------------------------

Again a release, because we did quite a lot, so it's due! Major new stuff is

support for ColecoVision (including Super Game Module and MegaCart mapper),

Musical Memory Mapper and Carnivore 2. And we have fixed a lot of long-standing

OPL4 emulation issues, thanks to Valley Bell. Furthermore, we overhauled the

Android port, but you'll mostly notice the scale factor 2 there. And several

other (sometimes very long standing) issues were fixed.

Here's the list with all highlights and details:

MSX device support:

- fixed 16 year old bug regarding sprites behaviour as shown in Ash Guine 3

- fixed exact formula for noise generation on AY8910 (PSG)

- made memory mapper ports readable on MegaFlashROM SCC+ SD, conforming to the

  latest version of this cartridge

- added new machines: Sony HB-G900AP (thanks to Louthrax), Eurohard/Radofin

  Dragon MSX (thanks to MAME), Yamaha CX7/128 and CX7M/128 (thanks to Peter

  Hanraets), Al Alamiah Sakhr AX230, Sanyo MPC-2, Yamaha CX11 (thanks to

  Tabajara Labs) and Toshiba HX-32 (thanks to Jorge Janaite Neto)

- added new extensions: Musical Memory Mapper, Carnivore 2 and SN76489 (on the

  same I/O port as PlaySoniq)

New or improved emulator features:

- fixed some crashes when using very high Z80 frequencies

- improved tab-completion to initially hide internal procs, until you specify

  the namespace

- many updates to the software database

- many updates to the VGM recorder script, thanks to Niek. Use 'help vgm_rec'

  to find out about the new subcommands. Sample RAM content is now logged even

  when starting recording after the sample kit is loaded, actual data recording

  starts automatically when data is sent to the chip, the proper OPL4 init data

  is automatically written to the VGM file, and many more things.

- changed default machine symlinks to JP machines (for applicable systems)

- many robustness fixes against bad XML config files

- added videosource setting to OSD menu, GFX9000 is getting more popular

- changed fixed scale factor from 1 to 2 on Android

- added OSD menu button to open the main menu for Android, as (most?) modern

  Android devices do not have a menu button anymore

- OSD menu: fixed issue of getting stuck in an unreadable directory when

  browsing for a file (e.g. on Android)

- added scrollbar when showing lists in OSD menu, as a visual cue on the length

  of a list; the scrollbar cannot be dragged

- fixed crash in hq/hqlite scalers in interlace modes

- fixed frame skipping when doing 'debug continue'

- fixed function keys not working anymore when console is open on macOS

- exposed tile viewer widget to the console (try "about tile")

Build system, packaging, documentation:

- upgraded C-BIOS to release 0.29a: default to 60Hz generic international

  config

- to load older savestates, added all C-BIOS ROMs shipped with openMSX 0.7.0

  and later for your convenience

- put several pieces of code under unit-test with the Catch2 framework

- added svicpm2dmk utility so disk images from the web can be converted to a

  suitable DMK file for use with the SVI-707 drive with CP/M ROM

- reworked complete Android port build. Now uses NDK 18b and recent version of

  commandergenius Android SDL port and all other 3rd party libraries are built

  by the openMSX build system. Minimum required Android version is now 4.1.

- removed all hand-made ARM and 32-bit x86 assembly code

- fixed version information of application on macOS

- added workaround for FreeType no longer installing its config script

- enabled retina support on macOS

- advise people to compile with Xcode 9.4.1 on macOS, not Xcode 10 (see issue

  #1126)

openMSX 0.14.0 (2017-08-03)

---------------------------

This release is another mix of some new features and additions and a lot of

smaller fixes and improvements. This release adds support for Konami Ultimate

Collection and basic emulation for the Spectravideo SVI-318 and SVI-328 pre-MSX

computers, increases FDC accuracy in such a way that we think all copy

protections (captured in a DMK file) should now run in openMSX. Moreover, we

now put the SDLGL-PP renderer as the default, so let us know how that works for

you. You can of course always set the old default setting for your system if

you don't like SDLGL-PP. But then we would really like to know why... We also

removed the Windows DirectX sound driver, as it was buggy and caused a lot of

complaints. And finally, we added a button in the top left corner to easily

invoke the OSD menu.

Here's the list with all highlights and details:

MSX device support:

- fixed VDP type of Sony HB-501P

- fixed a bug that caused hangups on some machines when resetting during the

  logo animation

- fixed ROM block debuggable for Sunrise IDE

- improved accuracy of WD2793 FDC and disk drive emulation

- added support for Spectravideo SVI-318 and SVI-328 pre-MSX computers:

  - most SVI support was implemented by Tomas Karlsson. With NYYRIKKI's help

    we fixed most last details

  - added in Contrib a tool to convert SVI disk images to DMK so they can be

    used in openMSX

  - added SVI support to several scripts (thanks to NYYRIKKI): cashandler,

    type_via_keybuf, listing

  - note the following limitations:

    - only WAV images are supported for cassettes. The stereo feature

      (music/sound on the other channel) is not supported.

    - only DMK disk images can be used

    - nothing is done to prevent the user to mix MSX and SVI hardware/software.

      This will not work, of course. As we are not SVI enthusiasts ourselves,

      we rely on contributions from others for the SVI support.

- added accurate M1 cycle emulation

- added support for ASCII8 mapper with 32kB SRAM

- added initial support for the ASCII paddle input device (paddle 1 and 2 only)

- added new machines: Bawareth Perfect MSX1, Al Alamiah AX370 (thanks to

  alshamaa), and as already mentioned: Spectravideo SVI-318, SVI-328 and a

  superexpanded SVI-328.

- added new extensions: Konami Ultimate Collection, ASCII Japanese MSX-Write,

  ASCII Japanese MSX-Write II and Tecall TM220 MSX-RAMFILE

New or improved emulator features:

- performance improvements:

  - reverse feature

  - hq resampler

- fixed issue with remote connections on Mac OS X/FreeBSD

- changed default sound driver on Windows to SDL, because the DirectX sound

  driver has been removed

- fixed creation of new HD images

- changed the default renderer to SDLGL-PP

- (probably!) fixed stability of MIDI-in on Windows. Unfortunately we didn't

  find someone to help us test this properly

- also improved stability on external connections in general

- allow to specify initial content for flash ROMs. This way it is possible to

  use MegaFlashROMSCC+SD like how the actual hardware is also shipped:

  preflashed.

- several improvements on the listing command (thanks to NYYRIKKI)

- added automatic file numbering for record_channels

- added a tron script (thanks to NYYRIKKI)

- added script that records to a new AVI file if the framerate changes (thanks

  to BiFi and FiXato for their initial version)

- added mapper selection to OSD menu for unknown ROMs

- automatically pad ROM files if they are not a multiple of the block size,

  instead of refusing to run that ROM

- added OSD button to invoke OSD menu in the top left corner

- added VGM recorder script (by Niek Vlessert) to help you record MSX songs

  into VGM files, supporting PSG, MSX-MUSIC, MSX-AUDIO, OPL4 and SCC

Build system, packaging, documentation:

- migrated from SDL threads to C++11 threads

- removed support for Maemo5

- moved Windows build to Visual Studio 2017

- upgraded C-BIOS to release 0.28

openMSX 0.13.0 (2016-07-31)

---------------------------

This again was meant to be (mostly) a bug fix release, but again it also has

some nice additions and improvements to enjoy. Important improvements are much

better support for VDP I/O delay in turbo machines (fixing graphics issues due

to too fast VDP access there), more accurate MSX1 color palette, progress

reporting for long operations and ALSA MIDI-out support for Linux. This is also

one of the first releases that drops support for older platforms: Windows XP,

Dingoo A320 (but introducing support for GCW Zero) and non-64-bit MacOSX. If

you still want to run openMSX on these, you'll be stuck on using a previous

release or start maintaining these platforms yourself.

Here's the list with all highlights and details:

MSX device support:

- fixed bug in ASCII-8 mapper of MegaFlashROM SCC+ (SD)

- fixed bug in border drawing in text mode with YJK/YAE bits

- fixed bug in LMMC VDP command that appeared in Baltak Rampage greetings part

- fixed bug in YMF278 (OPL4 wave part) preventing samples to be played sometimes

- improved R800 timing for the CALL instruction

- added missing hardware VDP delay in turbo mode of MSX2+ machines

- improved accuracy and completeness of the Matsushita switched I/O ports

  device:

  - added bits on turbo status and presence

  - added the device to the Sanyo MSX2+ machines (without SRAM and turbo)

  - removed fixed VDP I/O delay (because it is linked to the T9769 engine)

- added support for the different fixed VDP I/O delays of the different T9769

  engines and added these to the configuration files of the machine that have

  these (as far as that is known)

- added support for Epson Chakkari Copy, thanks to Rudolf Lechleitner and

  Enrico Barbisan

- added 2MB MegaRAM extension (thanks to Mauricio Braga)

- added MIDI Interface 3 extension (cart that implements turboR GT internal

  MIDI without BIOS ROM)

- added support for mapper of Japanese MSX Write

- added support for Spectravideo SVI-707 disk drive

- added support for the V9990 POINT VDP command

- added support for more realistic TMS VDP pallettes: it's now possible to

  specify the saturation for the Pb and Pr channel (this is dependent on the

  analog electronics in the MSX video circuit) which affects the palette. E.g.

  all machines with TMS9x2x have a brighter palette now, as they should.

- added weird color palette of the Fujitsu FM-X RGB output (3 bit RGB)

- added a high-resolution timer extension: a cartridge with a 32-bit counter

  that counts at 3.57 MHz. Useful for debugging and reverse engineering. Only

  one such real cartridge exists :)

- added new machines: Aucnet NIA-2001 MSXturboR (thanks to PiterPunk/NYYRIKKI),

  Frael BRUC_100 version 1 and 2 (thanks to RJP, FRS, et al), Pioneer UC-V102

  (thanks to PiterPunk), Victor HC-80 (thanks to Daniele), Toshiba HX-23F and

  HX-23 (thanks to FRS)

- added new extension: Sanyo MRS-001 RS-232C cartridge (thanks to mtn)

New or improved emulator features:

- fixed bug in parsing remote command XML (causing e.g. ROM names with special

  characters not to get communicated to openMSX correctly from Catapult)

- fixed crash in 'reverse goback'

- fixed inserting a slotexpander in a specific slot

- fixed slowness issue when taking screenshots frame by frame

- fixed support of files larger than 2GB (e.g. hard disk images) on Windows

- fixed VDP status flag when using cmdtiming broking (infinitely fast VDP

  commands)

  reversing

- made joystickN_deadzone setting's numbering consistent with joystickN_config;

  both are now 0-based

- added debuggable for printer port, containing strobe and data byte

- added experimental support for ALSA MIDI out (Linux): now it's much easier to

  connect MSX MIDI out devices to a soft synth or other application on Linux

- improved support for UNC paths on Windows (network drives)

- added a script to speed up the type command: type_via_keybuf (thanks to

  NYYRIKKI for the initial version). Default type implementation can now be

- updated Visual Studio projects to Visual Studio 2015

- dropped support for Windows XP, because it seems Visual Studio 2015 has bugs

  in supporting it

- dropped support for Dingoo A320, because its toolchain is now so outdated

  that it can't compile the openMSX source code any longer

- added build, packaging and documentation support for GCW Zero

- dropped support for universal binaries on Mac OS X, as all supported Mac OS X

  versions require x86-64 CPU's

- updated Tcl to 8.5.18

- updated libpng to 1.6.20

- now optionally link to libasound on Linux (for the ALSA MIDI support)

- added debug flag to build system that shows which commands are executed:

  make V=1

- improved description on how to use MegaFlashROM SCC+ SD

openMSX 0.12.0 (2015-09-12)

---------------------------

This was going to be (mostly) a bug fix release. But at the end we also got

inspired by Grauw to add a lot of MIDI devices. And, reviewing what we changed

the last 10 months, we saw that we also got loads of help from several people

to add many new machine configurations and added some fun stuff like Sensor Kid

and (experimental) Beer IDE emulation. On the emulator features category we

give you stuff like triplesize video recording, some TAS enhancements and a

callback for too fast VRAM access.

So, enjoy this 'various features and bug fixes' release!

Here's the list with all highlights and details:

MSX device support:

- fixed (S)RAM writing on turboR

- fixed border color in screen 11/12

- fixed some details of SD card emulation (found with FUZIX)

- fixed clipping bug in sprite-mode-1 drawing

- fixed crash in openMSX when using the AVT DPF-550 extension

- fixed support of 8kB RS-232C ROMs (which is the only correct size!)

- fixed emulation of joystick mode of the mouse

- fixed broken MegaFlashROM SCC+ (introduced with openMSX 0.11.0)

- improved trackball movement emulation so that JoyTest can also detect it like

  on real hardware

- fixed touchpad joystick pins (fixing detection in JoyTest)

- tweaked volumes of SFG-01/05 against the PSG

  MB-H3 (thanks to Werner Kai) and Yamaha AX350IIF (thanks to Rudolf Gutlich)

New or improved emulator features:

- added "too_fast_vram_access_callback": you can now run a Tcl script when the

  running MSX software accesses VRAM too fast, e.g. break to debug

- added display of 'movie length' in TAS mode. This is the length of your

  'movie' if you upload it to tasvideos.org

- added -triplesize to video recorder: allows creation of video files in

  960x720 pixels, for which YouTube renders videos at 60 fps.

- some fixes in keyboard mappings

- fixed slow console when emulation speed is very low

- add a snapshot 'near the end' to the OMR when saving it, allowing quicker

  continuation of the replay after loading it

- similarly, add snapshots when fast-forwarding to the target time, so they

  can be used to jump back more quickly

- show reverse bar in green when replaying in viewonly mode

- added a converter from/to OMR to/from text, which allows you to more easily

  edit the OMR outside of openMSX

- improved implementation of 'auto-save' feature of replays: the setting will

  now persist over openMSX sessions

Build system, packaging, documentation:

- replace mingw32 build support with MinGW-w64 build support on Windows

- updated our website and other URL's to point to http://openmsx.org/ or

  GitHub

openMSX 0.11.0 (2014-11-08)

---------------------------

This release brings you the following important new features: VDP access timing

now also for MSX1 modes (corruption with too fast VRAM access will be visible

now), implementation of most defailed differences between all used VDP chips

and emulation of MegaFlashROM SCC+ SD.

On top of that, there are some important (long standing) bug fixes, like the

proper implementation of envelopes for MSX-AUDIO, fixing for example "Copy is

Crime" by Impact.

And last but not least, a lot of work was done under the bonnet, giving you

even better performance and preparations for the future.

Here's the list with all highlights:

MSX device support:

- VDP:

  - implemented access timing also for character and text modes (both for MSX1

    VDP's and V99x8): too fast VDP access will now cause corruption on openMSX

    too

  - added support for specific MSX1 VDP's (mostly thanks to hap for all the

    research):

    - the exact VDP type can now be specified in the config file

    - differences between Toshiba T6950/T7937A, TMS99xx and TMS91xx MSX1 VDP's

      are now emulated (except sprite cloning)

    - updated many machine configs with the proper MSX1 VDP type (where known,

      additions/corrections are welcome!)

  - implemented that V99x8 does not support undocumented mixed modes

  - fixed bug in 5/9th sprite detection status register

  - added I/O port mirroring to machines of which we are certain it exists

- MSX-AUDIO (Y8950) and related:

  - fixed envelope for MSX-AUDIO (Y8950), the infamous legato-envelope bug is

    now finally fixed!

  - fixed handling of key-off for percussive tones

  - fixed detection of Philips Music Module in Tetris II Special Edition

- added emulation of MegaFlashROM SCC+ SD. Note: the implementation is such

  that existing software works on it, but do not fully rely on it when

  developing for this cartridge!

- improved Sony HBI-55 emulation

- fixed some details in several machine configurations

- fixed KANA/CODE key not working in CHARACTER input mode

- added the following machines: Daewoo CPC-51 Zemmix V, Daewoo CPC-300E,

  Toshiba HX-51I, Yamaha YIS-503IIR, Toshiba FS-TM1, Sanyo MPC-10 (Wavy 10),

  Yamaha CX5MII, Fujitsu FM-X (thanks to NYYRIKKI, Werner Kai, Maxim Vlasov and

  Alex Krasivsky)

- added the Casio KB-7 and KB-10 docking stations (note: these extensions only

  work with the Casio PV-7 and MX-10 respectively; do not be worried

  when they appear to be not working according to Catapult!)

- added the MSX Acid Test machines, contributed by FRS

- added the Gradiente CT-80E 80 column card extension, thanks to Maurício Braga

New or improved emulator features:

- added de-flicker video filter via new 'deflicker' setting. Use this to remove

  flickering in cases like the dvik demos where 105 colors are simulated on

  MSX1 by alternating different native colors. It's disabled by default.

  - speed up execution of Tcl scripts

  - many various other optimizations

- fixed auto_enable_reverse (set/unset auto enabling reverse at startup)

- rewrote most OpenGL 2 code to be more compatible with OpenGL ES

- improved guessing of mapper type for 64kB ROMs

- fixed a bug with watch_points affecting the execution flow

- fixed corruption in XSA disk images

  'fast_cas_load_hack_enabled' setting to on

- joysticks/controllers:

  - added setting to configure dead zone for joysticks

  - added support for joystick hats (can be used just like buttons)

  - improved support in OSD menu (take deadzone into account)

- added dir-as-disk support for the OSD menu

- removed experimental libao sound driver

- added support for R-ALT on Korean keyboard (thanks to Miso Kim)

- TAS: added possibility to query the length of the current replay (defined as

  the time stamp of the last input)

Build system, packaging, documentation:

- even more use of C++11 features, when using gcc use 4.7 or higher

- removed build dependency on libxml2

- removed many/all unused features/libs from the build system

- added support to cross compile with MinGW-w64 for (at least) 32 bit Windows

  using Linux

  you to get :)

- changed packaging method to include stuff by default instead of exclude stuff

  by default

- fixed native compilation on mipsel

- upgraded C-BIOS to release 0.27

Build system, packaging, documentation:

- Added build support for DragonFly BSD, thanks to John Marino

openMSX 0.9.0 (2012-08-12)

--------------------------

This release improves a lot on accuracy of floppy support, especially by the

introduction of support for the DMK format. This means it should be possible to

run all MSX disk software without patching it.

Furthermore, our efforts to improve performance has some results: start up time

has almost halved on a Dingoo A320!

Here's the list with all highlights:

MSX device support:

- Bug fixes:

  - overscan: 512x512 demo by NYYRIKKI and Don't Cock It Up by Matra now work
