We have a couple of members of the MAME dumping union on here, if you could post the link they may be able to add it for you as well
HBMAME stores all the hacks for sure: https://github.com/Robbbert/hbmame/...fb27c4c85d76/src/mame/drivers/cps1.cpp#L14387This can also be cause by wrong dip switches, there's a freeze dip. SWC DIP4..
If you can drop the roms somewhere and a full picture of the board, we can submit it to MAME if it's undumped. I'm not sure all the hacks are in the mainline, there are some other custom mame builds with a load more hacks i think.
