Disabling TMSS

Make the macro TMSS_ENABLE=0 in tmss.h; This macro can be defined externally (in the build script or environment variables)

Audio, Video dump format:

Audio and video are dumped in raw format. Audio:

16-bit stereo, Little endian, 223722 hz NTSC / 221681 hz PAL

Video:

400x300 RGB (8 bits per channel)

SMS Mode

Run the emulator with the -m3 flag

Savestates

To implement save states, the usual approach is applied, where internal contexts are serialized sequentially to a file. This is a simple and time-tested method of saves in emulators. Of course, over time, the format of save states becomes incompatible, but for this you just need to maintain the codebase, it is a natural and inevitable process.

Save state controls:

  • F5: Quick Save (nukedmd.sav)
  • F7: Quick Load (nukedmd.sav)

Reset Button

Hold down F12 for a short time.

Note: The Overdrive 2 demo has an issue loading Z80 microcode and requires pressing Reset after the first run (behavior is similar on real hardware).
