CPS1 single board bootlegs
sound hardware: PIC16c57, oki M6295 (no z80)
Games known to use this h/w:
Cadillacs and Dinosaurs 930201 ETC
The Punisher 930422 ETC
Saturday Night Slam Masters 930713 ETC
Warriors of Fate 921002 ETC
(Note, these are all CPS1.5/Q sound games)
Generally the sound quality is very poor compared to official Capcom hardware.
Both music and sound effects are produced by just a single M6295.
Background music consists of short pre-recorded clips which loop continuously.
Currently all games have no sound emulation due to the PICs being secured/protected.
Unless any un-protected PIcs ever turn up (unlikely) then "decapping" of working chips is probably the
only way valid dumps will ever be made.
Status of each game:
--------------------
dinopic: No sound.
dinopic2: No sound.
dinopic3: No sound. Some minor gfx priority issues, confirmed present on real board.
jurassic99: No sound.
punipic, punipic2: No sound. Problems in Central Park. Patches used.
punipic3: Same as punipic, and doors are missing.
slampic: No sound. Some minor gfx issues (sprites on character select screen).
slampic2: No sound. All gfx issues confirmed present on real board.
wofpic: No sound. Some minor gfx issues (sprite priorities mainly). https://youtu.be/Ozlb2gNRSfs
all dinopic sets have some priority issues with sprites overlapping foreground objects on certain levels
brightness circuity present on pcb?
slampic2 yes
dinopic3 no
jurassic99 no
others tbc... assume no for now
