- missing sprites and priority - missing sprites and priority
Known Issues: Known Issues:
- no dual monitor support - 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.
- games seem to think they're in dual-monitor mode when they're not - Current draw state could be improved optimization-wise (for example by supporting it in the core in some way).
- speed in some sets is incorrect (for dual monitors I'm guessing it should - sprite palettes are not entirely right
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
