Mame version 0.170 I'm using this version because it is (one of?) the last 32 bit supported by MAMEUI and the system I'm using right now is 32 bit. Puzzle Uo Poko will not save. Shift F7 does nothing, but F7 will ask for a position to load from.
My real question is is there an easy to find out about bugs and if/when they were fixed? Or is going through the "what's new" for each MAME version the only way. I would like to figure out how to answer these types of questions for myself.
