Finish Lock-On driver
Soon.
Add support for Maygay M2 hardware
- Add MC68306 support
An M68EC00 core with integrated DUART (my old friend MC68681), DRAM controller and internal address decoding (32-bit address resolved to 7 /CS pins). Dunno how to handle the address decoding cleanly...
- Add OKIM6650 support
Just another 8-bit PCM/4-bit ADPCM playback IC with a couple of additional features (e.g. random playback, beep mode).
- Add PIC16C6x support
A PIC16C64 appears to handle all I/O.
Improve BFM Cobra driver
- Hook up Cobra boardset and write tests to exercise unknown hardware features.
- Add support for Cobra II.
- Improve 6850 ACIA emulation.
Self-reminders
- Use mame_printf_ functions (see mame.h).
- Alternatively, use popmessage().
- Remember to set the GAME_SUPPORTS_SAVE flag if saving state.
- Saved state can be viewed in the debugger.
- When updating stuff per scanline "Use a timer to fire at the start of each scanline. Do your clocking in the timer callback for that scanline. Then use video_screen_update_partial() to force the VIDEO_UPDATE callback to be called for that scanline so you can do the mixing and rendering directly to the game bitmap."
