So I have successfully loaded SNES9X onto my PSP Slim. I have d/l a zip with 800 SMC roms in it. None of them load. However I downloaded a zipped rom and it works fine. How do I zip my 800 roms so they will work? I have tried using winzip. The zip files that do work are around 1200KB but the ones I personally zip are 2kb. What am I doing wrong?
