here are some points 1. downloaded street fighter 2 turbo on emuparadise 2. tried playing the game on my 64 bit mame 3. didn't work. it identified the game but it failed to play as it is missing rom or chd images 4. tried downloading qsound and tried adding it on the rom file... didn't work I tried researching the problem leading me to some conclusions. Either the rom is too old for this emulator or I am doing something completely wrong. edit: I'm using this on a windows 7
