Ooooh boy that one is a sweetheart.
Looks like Street Fighter Zero 2 (JPN) which is a cool fun game, well worth the effort.
The B board is pretty much a gonner, I’ve done a lot of repairs on CPS2 and that is way beyond my ability
Good news is that the game can live on ! You can use those chips on pretty much any B board, just need to set the jumpers correctly, use a matching GAL, and write the keys (infinikey is my favorite)
Should be a fun project!
Edit. Per the link ekorz posted, CPS2 has been fully reverse engineered so if you have infinite patience…
