TODO:
- Correctly implement characteriser protection for each game.
- Mating Game animation and screen still slower than it should be, AVDC timing/IRQs?
- Get the BwB games running
* They have a slightly different 68k memory map. The 6850 is at e00000 and the 6840 is at e01000
They appear to hang on the handshake with the MPU4 board
- Find out what causes the games to hang/reset in service mode
Probably down to AVDC interrupt timing, there seem to be a number of race conditions re: masks
that need sorting out with proper blank handling, etc.
that need sorting out with proper blank handling, etc. I'm using a scanline timer to drive an
approximation of the SCN2674 scanline logic, but this is perhaps better served as a proper device.
- Deal 'Em lockouts vary on certain cabinets (normally connected to AUX2, but not there?)
- Deal 'Em has bad tiles (apostrophe, logo, bottom corner), black should actually be transparent
to give black on green.
