My son broke bluray player so can`t play black ops any more and was trying load up some snes iso.But really dont no where to start .Thanks if anyone can help.
:dontknow:

downgrade theres some tuts on here

post your model number first

Snes roms tend to work better than snes iso's, never try putting optical discs in the cartridge slot.
