TODO:
|
||||
- Fix Sweet Gal/Sexy Gal/Sexy Gal Tropical layer clearances (more protection?);
|
||||
- Understand why Night Gal Summer title screen gets wiped out (protection issue);
|
||||
- NMI origin for Sexy Gal / Night Gal Summer
|
||||
- unemulated WAIT pin for Z80, MCU asserts it when accessing communication RAM
|
||||
- Sexy Gal uses an additional NCS for a sample player, understand how to make it play anything (tries to read port $00 but it's always zero);
|
||||
- Sweet Gal hangs after winning a round;
|
||||
- Other games in the driver also have sample ROMs, it is unknown how they are supposed to playback tho;
|
||||
- Understand why Night Gal Summer title screen gets wiped out and why it doesn't get displayed at all during attract mode (protection issue?);
|
||||
- NMI origin for Sweet Gal / Night Gal Summer;
|
||||
- unemulated WAIT pin for Z80, MCU asserts it when accessing communication RAM;

Notes:

- Night Gal Summer player hand is at $f801 onward
