What do patches exactly do?
I have a psx/ps1 iso. I also have a psx/ps1 cue & bin file. In order for me to play these two game files on my ps1-- 'small system' do I have to patch these games up? Is it possible to patch an iso? Will patching these two game files, then burning them allow me to play the game on my ps1 console? Please help me with some information or experience you have.
