{Logs the contents (e.g. registers) of a given debuggable or replays such a log.
5 
The state of the debuggable is saved to a log file every VDP frame. Note that
6 
it does not take into account different VDP interrupt rates.

Usage:
9 
   reg_log record <debuggable> [<filename>]   record <debuggable> to <filename>
10 
                                              (default: <debuggable>.log)
11 
   reg_log stop <debuggable>                  stop recording <debuggable>
12 
   reg_log play <debuggable> <filename>       replay log in <filename>
13
14 
Examples:
15 
   reg_log record "PSG regs"        start logging PSG registers to
16 
                                    "PSG regs.log"
17 
   reg_log record memory mem.log    start logging memory to file mem.log
18 
   reg_log stop "PSG regs"          stop logging "PSG regs"
19 
   reg_log play "PSG regs" my.log   replay the log of "PSG regs" in my.log
