I recently recieved a backups i ordered and when i try to boot some of them up i get a dirty disc error, i even copied them to the hard drive and patched them and they still get the same error!I am running the evox 2.5 bios.

try using 4977.

whats that a bios or for hex editing?

Thats the Xecutor bios, one of the more current ones. It gets past an older media check that some relatively new games use. Evox M7 has this capability as well. Either work with your evox dashboard, so feel free to use whichever you just happen to find.
