You need to learn how to make and compare hash codes. Make hash from your dump e compare with the results of the redump site. A good game for PSX is a redump image. Older system use "no-intro roms", like, Genesis, NES, etc.Is it possible that the file is corrupted? I just want to play Rockman X3 / Mega Man X3, that's it T.T
Anyway, look for the hacks roms Zero Project 3.1 and Zero Project 4.0 for MMX3 (SNES). You will love it!
