TODO:
- Opto coin chutes, similar if not same as taito/pkspirit.cpp
- parentj: throws "MESSAGE ERROR" on boot, hold ALL CLEAR SW and RESET (keys 9 and R) for a little while.
Notice that holding SERVICE1 (reset) implicitly means no NVRAM restore.
- 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;
@ -40,7 +37,9 @@ TODO:
Notes:
- Press R to reset errors;
- parentj: if it throws "MESSAGE ERROR" on boot then it needs All Clear SW being pressed,
which in turn is tied to irq 7 service for proper initialization of NVRAM.
POST expect that a credit string is available at $10156a cfr. https://tcrf.net/Parent_Jack
