how many disk errors are bad?

i have some old games.. they ripped with a lot of errors so what is a common amount of errors a rip has?

What do you mean? PSP games? They can't be really old...

PSone games, sorry. with all the hype of the playstation emulator i just kinda assumed. my fault.

so how many disk errors for psone games.

Just use iso producer if you want to play your psp games on ps1p

Yeah, actually there shouldn't be even ONE error. Well, probably the disk you're trying to rip is copy-protected, but hey, there are ways to circumvent this problem...

i ripped grand tourismo2 for my PC once disc1 had 3or4 read errors and worked fine
disc2 had more than 10 errors and crashed when i used certain menus
ps1 cds have kinda bit of spare data so if a disc gets scratched
to some degree it remains still readable
