You still haven't answered the question on how to fix it... and honestly this is the closest thing I can find on fixing the save problem which is extremely annoying because I'm sure i would love to play, but without it saving correctly I can't.
I swear like 99% of arcade games wouldn't even exist these days outside of MAME the arcade machines are old and busted very few ever saw any sort of home conversion
I mean if a company could use AI to do the work of a home conversion for essentially free why not? The rights for some games are completely lost though
