- missing sprites and priority
Known Issues:
- no dual monitor support
- games seem to think they're in dual-monitor mode when they're not
- speed in some sets is incorrect (for dual monitors I'm guessing it should
output alternate frames to alternate monitors, but due to other bugs it
just causes the game to run twice as fast as it should?)
- synchronization and other oddities (rungunu doesn't show attract mode)
- swapped P12 and P34 controls in 4-player mode team selectet (real puzzler)
- P3 and P4 coin chutes not working in 4-player mode
- sprite palettes are not entirely right
- CRTC and video registers needs syncronization with current video draw state, it's very noticeable if for example scroll values are in very different states between screens.
- Current draw state could be improved optimization-wise (for example by supporting it in the core in some way).
- sprite palettes are not entirely right
