ToDo:
- Fix protection simulation in Birdie Try (that part needs a complete rewrite);
- IPT_VBLANK doesn't work properly, that's particularly true for Birdie Try hang when you clear an hole (in any way it never clears out)
and for Boulder Dash fade in / fade out transitions (they are far too slow right now);
- graphics are completely broken in Automat and Secret Agent (bootleg);
- Fighting Fantasy (bootleg) doesn't boot at all;
- Hook up the 68705 in Midnight Resistance (bootleg)
(it might not be used, leftover from the Fighting Fantasy bootleg on the same PCB?)
- Hook up the 68705 in Midnight Resistance (bootleg) (it might not be used, leftover from the Fighting Fantasy bootleg on the same PCB?)
- Get rid of ROM patches in Sly Spy and Hippodrome;
- Accurate pixel clock parameters;
- background pen in Birdie Try is presumably wrong.
- Finally, get a proper decap of the MCUs used by Bad Dudes and Birdie Try;
