So, I went and downloaded .127u8 of mameuifx32. Then a whack of games I was playing stopped working... and they all seem to relate to this "a-board plds" stuff. I'm wondering, how can I get new mame working for my 'old' roms, and if that's not an option, how can I insert the new files (find them first) into the old roms to make new roms that'll work again?
TIA
