Video : Text mode works, but is rather slow, especially scrolling up (uses multple "raster copy" commands).
Graphic layers work.
BG tiles and sprites work, but many games have the sprites offset by a small amount (some by a lot
)
Still a few minor priority issues around.
Other issues:
Bus error exceptions are a bit late at times. Currently using a fake bus error for MIDI expansion checks. These
are used determine if a piece of expansion hardware is present.
Keyboard doesn't work properly (MFP USART).
Supervisor area set isn't implemented.
Some minor game-specific issues (at 28/12/08):
Pacmania: Black squares on the maze (transparency?).
Salamander: System error when using keys in-game. No error if a joystick is used.
Some text is drawn incorrectly.
Kyukyoku Tiger:Sprites offset by a looooong way.
Dragon Buster: Text is black and unreadable. (Text layer actually covers it)
Tetris: Black dots over screen (text layer).
Parodius Da!: Black squares in areas.
