Driver by Roberto Fresca & Grull Osgo. Games running on this hardware: * Five Clown (English, set 1), 1993, IGS. * Five Clown (English, set 2), 1993, IGS. * Five Clown (Spanish, hack), 1993, IGS. This hardware seems to be based on Bonanza's Golden Poker, but on steroids... Double CPU, FM sounds, samples system, different encryption schemes and other complex things mark the difference.

The checksum routine starts at $FE1D Once checksumed the whole range, compares the result with a harcoded value. If match, jumps to a subroutine that prints "ROM x ERR". If doesn't match, prints "ROM x OK" So... It's inverted. Seems that someone replaced the BEQ's instructions with BNE's, to pass the checksums. $FE1D ---> checks ROM 5 (4000-5FFF) $FE44 ---> checks ROM 6 (2000-3FFF) $FE6B ---> checks ROM 7 (E000-FDFF) ******************************************************************************* Game Settings ------------- From a datasheet.
