dec8.c

0.33b5 [Bryan McPhail]


TODO:

- Support coinage options for all i8751 emulations.

- Super Real Darwin 'Double' sprites appearing from the top of the screen are clipped

- Strangely coloured butterfly on Garyo Retsuden water levels!


NOTES:

- All Data East 8 bit games use a 6502 for sound (some are encrypted), all games except Cobracom use an Intel 8751 for protection & coinage. For these games the coinage dip switch is not currently supported, they are fixed at 1 coin 1 credit.

- Driver: Thanks to Jose Farreras for Super Real Darwin information!
