###Release R48 ("Cadmium")
31
32
*Features/Fixes
33
* Emulated VERA SPI clock has been updated to half of the VERA clock speed rather than the CPU clock.
34
* Trace for ROM banks 13-15 (x16edit and Basload) is now supported [stefan-b-jakobsson]
35
* Fixed debug reads from the stack and a few unbounded values in the debugger display
36
* VERA PSG: for the saw and triangle waves, the inverse of the pulse width value is XORed with the value of the wave. This is the behavior of VERA 47.0.2 on hardware. [m00dawg]
37
* Allow setting the amount of RAM in the web version of the emulator [JimmyDansbo]
38
* Windows 11: Rounded corners should no longer cut off the lower left and lower right of the emulator window.
39
* New memory statistics feature [irmen]
40
* HostFS: Implement DOS "T"ell command
41
* Debugger now includes elapsed cpu clocks since the last breakpoint or step
42
* 65C816: Fixed stack relative indirect address calulation wrongly using the direct page [Fulgen301]
43
* 65C816: high bytes of .X and .Y are now cleared when PLP or RTI set x=1 [cnelson20]
44
* 65C816: PEI no longer does improper page wraparound, `[dp]` indirect modes now properly read the address. [Fulgen301]
45
* More changes in the [ROM](https://github.com/X16Community/x16-rom/tree/r48#release-48-cadmium).
46
47
###Release 47 ("Roswell")
48
49
This is a major release with numerous bugfixes, as well as introducing 65C816 support.
50
51
*Features/Fixes.
52
* Optionally emulate a 65C816 CPU, selectable via a new command line switch `-c816`. There is also a `-c02` command line switch to explicitly select 65C02 mode. [Fulgen301]
53
* In order to make room for the full 65C816 vector table, the R47 ROM relocates the "MIST" KERNAL signature from 0xFFF6 to 0xC008. Emulator has been updated to check for the signature in the newer location. [Fulgen301]
54
* Made IEC device addressing more flexible by preventing the HostFS from consuming every device number [DragWx]
55
* Improved timing calculations for HostFS operations to translate wall clock time to elapsed CPU ticks
56
* If HostFS is in use, the default `-abufs` audio buffer count is 32, otherwise 8. This should reduce audio stuttering for games which load assets from disk while sound is playing.
57
* HostFS can be changed to respond to a non-default device number. New command line option `-hostfsdev`. Using this option in conjunction with `-sdcard` allows both devices to appear on the system.
58
* Matching the VERA hardware feature, the layer config T256 bit can be used as a palette switch in tile and bitmap modes. Most useful in 2bpp and 4bpp depths, setting this bit on the layer forces the resolved high bit of the palette entry index to 1. For instance, in 4bpp mode, a tile pixel with index 1, on a tile configured with palette offset 6 would normally resolve to palette entry 0x61 (or 97 decimal), having this layer bit set will cause this pixel to resolve to palette entry 0xE1 (or 225 decmial).
59
* Copying VERA hardware behavior, the LINE IRQ can happen in the non-visible vertical blanking area.
60
* HostFS: empty filename now returns an error as appropriate
61
* IO2, the YM2151 range, is partially decoded on hardware. Emulator behavior now matches this so that the YM2151 is mirrored throughout the $9F42-$9F5F range.
62
* New command line switch `-nokeyboardcapture` causes capture mode to operate without intercepting OS-level keystrokes such as Alt+Tab.
63
* Improvements to `-wuninit` warnings to show the appropriate opcode and location of uninitialized accesses.
64
* Recognize the INTL1 key code, which exists on some keyboard layouts such as pt-BR.
65
* Update the 65C02 opcode table to properly handle multi-byte NOPs and update cycle counts.
66
*`-trace` output has been updated and enhanced, showing banks for effective addresses. Add listings for new banks.
67
* new `-longpwron` option to match SMC 47 long power button press behavior at power on.
68
* VERA FX: fix address resolution bug with 4bpp unaligned cache filling.
69
* VERA: DC_VSTOP was taking effect one scanline too late.
70
* SMC: update activity light logic. Hardware was mistakenly documented as allowing 255 PWM intensity levels, while in fact it is binary on/off.
71
* VERA PSG: update PSG volume table from VERA 47.0.0. Prior to this change, there were multiple PSG volume values at the low end that resulted in the same output level.
72
* SDL2: Set the application name to "Commander X16 Emulator", which shows up in the audio mixer, and in the screensaver inhibit application list on Linux desktop environments. This should be a bit more informative than "My SDL application".
73
* New `-pastewarp` command line switch that warps the emulator when receiving paste data either from the clipboard or from the `-bas` command line switch.
74
* HostFS: improve path parsing with both CMD and unix path syntax, particularly with absolute path names. DOS"MD//:TEST" now creates the directory in the FS root rather than erroneously in the current directory.
75
* VERA: DC_HSCALE and DC_VSCALE values > 0x80 now render as they do on hardware.
76
* SMC 47.0.0 fast PS/2 read support
77
* Now with native build for Apple Silicon (built on the GitHub MacOS ARM runner)
78
* More changes in the [ROM](https://github.com/X16Community/x16-rom/tree/r47#release-47-roswell).
79
80
81
###Release 46 ("Winnipeg")
82
83
This is mainly a bugfix release.
84
85
*Features/Fixes
86
* A change in the ROM caused controllers to have their buttons offset due to how the emulated VIA responds to polling. The issue was fixed in the ROM and while it was not technically an emulator bug and no changes were made to the emulator's joystick routines, it gets a mention here.
87
* HostFS: UNLSN was incorrectly setting the KERNAL status byte based on whether a file existed upon open. It has been changed to behave like CMDR-DOS. (discovered by [voidstar78])
88
* HostFS: Opening a file in Modify mode now properly creates file if it doesn't yet exist (discovered by [m00dawg])
89
* Audio: prevent `-sound none` from trying to use the uninitialized ymfm YM2151 library. The YM status register was also modified to always return 0 in this case. (discovered by [jestin])
90
* WebAssembly: improve handling of zip files without `manifest.json` [Cyber-Ex]
91
* GUI: If emulator launches in a window with the titlebar offscreen, move the window so that it is visible. (with help from [irmen])
92
* GUI: Mouse movement now uses relative motion in capture mode, which makes the position of the host mouse irrelevant while in capture mode.
93
* GUI: new `-capture` command line option to start emulator with mouse captured
94
* Testbench: miscellaneous fixes [irmen]
95
* More changes in the [ROM](https://github.com/X16Community/x16-rom/tree/r46#release-46-winnipeg).
96
97
###Release 45 ("Nuuk")
98
99
This is a minor release with respect to the emulator. The bulk of the changes are in the [ROM](https://github.com/X16Community/x16-rom/tree/r45#release-45-nuuk).
100
101
*Features/Fixes
102
* Revert VERA PSG amplitude resolution back to 6 bits. This was upped previously to match VERA firmware. It was subsequently reverted in VERA to make room for the FX feature. [akumanatt]
103
* Intellimouse support added to the emulated SMC, partially implementing the new feature in hardware SMC firmware 45.1.0. [stefan-b-jakobsson]
104
* Scroll wheel is supported (mouse device ID 3)
105
* Not implemented: Extra buttons (mouse device ID 4)
106
* New emulator debug register behaviors
107
* Reading from \$9FB8-\$9FBB in this order returns the 32-bit CPU clock counter, snapshotted at the time \$9FB8 is read. Previously the clock counter would remain in motion and the upper counter bits could roll over unpredictably.
108
* Writing to \$9FB8-\$9FBB has new behaviors:
109
* \$9FB8: resets the cpu clock counter to 0.
110
* \$9FB9: prints a debug message to the console `User debug 1: $xx`.
111
* \$9FBA: prints a debug message to the console `User debug 2: $xx`.
112
* \$9FBB: prints the UTF-8 representation of the ISO character to the console. This can be treated like a debug STDOUT.
113
* Before using any of these emulator debug registers, it's recommended to test for emulator presence first.
114
* Read from `$9FBE` and `$9FBF`. When running under the emulator, the returned values should be `$31` and `$36` respectively. If any other values are returned, you can usually assume to be running on real hardware. While the stock machine doesn't have any I/O devices that listen to the emulator I/O range, an add-on card could choose to use that same address space in the future for its own functions.
115
* New MCIOUT (blockwise write) implementation for HostFS, mirroring the feature in the kernal for use on SD card.
116
* New command key and capture behavior:
117
* Ctrl+M/⇧⌘M is always processed by the emulator to toggle (mouse/keyboard) capture, regardless of the state of the "Disable Emulator Keys" flag.
118
* Turning capture mode on disables all other emulator keys until capture mode is toggled off. While capture is on, the emulator also routes most OS shortcut key combos to the X16: for instance, Alt+Tab.
119
120
121
###Release 44 ("Milan")
122
123
This is the third release of x16-emulator by the X16Community team
124
125
*Features/Fixes
126
* Many changes to HostFS, including
127
* Fix regression for loading "`:*`" from HostFS while also using an SD card image
128
* Fix `-prg` and `-sdcard` options working together, which did not properly handle the case after emulator reset
129
* Proper wildcard behavior in dir filters and OPEN string
130
* Fix filetype directory filter command parsing
131
* Add `$=L` long mode directory listing to emulate the new feature in the ROM.
132
* Speed up directory filetype filter
133
* Add CMD/SD2IEC style directory navigation: `CD:←` to enter parent directory
134
* Partial emulation of case-insensitivity in filenames on case-sensitive host filesystems.
135
* This works in `OPEN` strings and directory names in commands (`CD:`, etc.) which do not contain a `/` character.
136
* It also works on the last path segment in relative or absolute paths in directory names or `OPEN` strings. In other words, if given a path specification containing one or more `/` characters, it will do only a case-insensitive search on the part after the final `/`.
137
* Proper translation between UTF-8 filenames and their ISO representations.
138
* Implement VPB behavior to match hardware [akumanatt]
139
* Fix BRK to have VPB behavior
140
* Support for additional keycodes (NumLock, Menu) [stefan-b-jakobsson]
141
* Fix debugger to set the correct bank for breakpoints [gaekwad]
142
* New `-fullscreen` CLI option
143
* Proper cleanup when the emulator exits when in full screen [irmen]
144
* FX emulation, which mirrors the features in the FX enhancement to the VERA firmware. See the [VERA FX Reference](https://github.com/X16Community/x16-docs/blob/master/VERA%20FX%20Reference.md) for details.
145
* Writing bit 6 and bit 7 together into VERA_AUDIO_CTRL now enables looping the PCM FIFO (and does not reset the FIFO). Any other write into VERA_AUDIO_CTRL disables looping.
146
* New `-opacity` CLI option for window transparency [tstibor]
147
* New support for screenshots (Ctrl+P/⌘P) [dressupgeekout]
148
* Fix small memory leak caused by pasting into the emulator
149
* Use relative mouse motion while in grabbed mode
150
* Remove `-geos` CLI option [dressupgeekout]
151
* New YM2151 audio core: remove old MAME core, replace with ymfm
152
* Allows for IRQs from the YM, requires specifying `-enable-ym2151-irq` on the command line
153
* Emulate hardware open bus behavior when reading from a device that doesn't exist in the `$9Fxx` space
154
* Reset via I2C command: defer machine reset to the main loop, which allows the I2C write routine to return cleanly.
155
* Fix 65C02 `BIT` immediate behavior [XarkLabs]
156
* New NMI trigger emulator hotkey, emulates Ctrl+Alt+Restore on hardware (Ctrl+Backspace/⌘Delete) [XarkLabs]
157
* Fix line artifact in application icon/logo
158
* Grabbing the mouse with (Ctrl+M/⇧⌘M) now grabs the keyboard as well. It allows the emulator to receive keystrokes and key combinations which would otherwise be intercepted by the operating system.
159
* Fix description of fill value in `makecart`
160
* New features implemented in the [ROM](https://github.com/X16Community/x16-rom/tree/r44#release-44-milan)
161
* Build
162
* Link-time optimization is now enabled by default
163
* Portability enhancements [dressupgeekout]
164
* Suppress clang warnings due to deprecated sprintf usage in ymfm lib [XarkLabs]
165
166
###Release 43 ("Stockholm")
167
168
This is the second release of x16-emulator by the X16Community team
169
170
***BREAKING CHANGE**
171
* The keyboard protocol between the emulated SMC and the KERNAL has changed, thus x16-emulator version R43 requires x16-rom version R43.
172
* This change also affects how the custom keyboard handler vector works (keyhdl). For details, see [Chapter 2 of the Programmer's Reference Guide](https://github.com/X16Community/x16-docs/blob/master/X16%20Reference%20-%2002%20-%20Editor.md#custom-keyboard-keynum-code-handler)
173
***Your Keyboard will not work unless** you are running
174
* R43 of both x16-rom and x16-emulator
175
* Features
176
* Updates to support translation from SDL scancodes to new keynum encoding supported by KERNAL [stefan-b-jakobsson]
177
* More granular support for RAM amount as argument to `-ram`
178
* Minor HostFS bugfixes and enhancements, including tying the activity light to HostFS activity.
179
* VERA updates: new support for 240p in NTSC/RGB modes. Chroma disable only works on NTSC.
180
* Stepping the debugger now supports stepping over `WAI`
181
* Debugger now shows the correct bank in the disassembly by default. [gaekwad]
182
* Debugger breakpoints are now bank-specific [gaekwad]
183
* Randomized RAM is now the default. New option: `-zeroram` [irmen]
184
* Host's mouse cursor is now shown unless either the KERNAL mouse is enabled or the mouse cursor is captured (Ctrl+M/⇧⌘M).
185
* Esc key is now Esc rather than STOP. Pause key sends STOP. (Ctrl+C is also recognized by the KERNAL as STOP)
186
* SD card emulation now responds to CMD9
187
* Emulated SMC can now assert NMI.
188
* Add `-mhz` option to select a speed other than 8
189
* When built with `TRACE`, the `-trace` output now shows the effective address for indirect and indexed opcodes and VERA data0/data1 reads and writes.
190
* New comamnd line option `-midline-effects` that supports mid-line changes to the palette or tile/sprite data. R42 always had this behavior, which results in performance degradation for programs write to VERA heavily if the host CPU is not fast enough. This behavior is now disabled by default. `-midline-effects` restores this optional behavior.
191
* New features implemented in the [ROM](https://github.com/X16Community/x16-rom/tree/r43#release-43-stockholm)
192
* Other
193
* Release builds have link-time optimization enabled which seems to help performance.
194
* Add git hash of build to `-version` string.
195
* WebAssembly enhancements in the supporting html/js [Cyber-EX]
196
* Fixed potential off-by one row with non-zero DC_VSTART.
197
* Prevent laggy hostfs reads from causing the emulator to warp to catch up by translating the wall clock time to elapsed 6502 clocks. This effectively makes HostFS MACPTR behave like a DMA card, including the possibility that it prevents the CPU from executing instructions while interrupt sources may have been waiting for service.
198
* Bugfix: Process multiple SDL events per frame. (Fixed choppy mouse movement if there were keystrokes in the keyboard buffer)
199
* Audio resampling and ring buffer fixes [DragWx]
200
* Build fixes on Mac
201

updated KERNAL with proper power-on message
548
549
###Release 9

552
553
LOAD"TETRIS.PRG
554
SAVE"TETRIS.PRG
