@ -31,8 +31,11 @@ TODO:
- Opto coin chutes, similar if not same as taito/pkspirit.cpp
- parentj: throws "MESSAGE ERROR" on boot, hold SERVICE1 and SERVICE4 at boot.
Notice that holding SERVICE1 (reset) implicitly means no NVRAM restore.
- sprite priorities
- interrupts (sources) - valid levels 4 (vblank), 5 (timer or from I/O), 6 (hopper signal)
- both games throws "HOPPER EMPTY" if pressing payout button after some time.
- parentj: lower part of dealer arm GFX is x flipped,
is it even supposed to be shown but rather be masked by the text layer?
- eibise: middle reel shows sprite wraparound glitch;
- interrupts (sources) - valid levels 4 (vblank), 5 (timer or from I/O), 6 (hopper signal?)
Notes:
- Press SERVICE1 to reset errors;
