I downloaded a bunch of roms for mame, cps2, and Turbografx 16. However, only one of my cps roms will load, most of my mame roms wont even show up, and of those only one works, and the turbografx 16 emulator doesn't recognize any of my roms. I know i put them all in the right folders, and I downloaded them from a very reliable site, from which all the roms I have gotten worked. What do I do?
