Well after bombing my V4 i went and bought a brand spanking new PS2.
Date Code 2D
I assumed this is a V7 and used such instructions. My PS boots up and plays originals just fine. But it wont play backups. A screen pops up says insert PS/PS2 format disc.
I have opened it up and rechecked all wires and I am sure that everything is correct. So do you think I have a bad chip? Or maybe its not compatible w/ my PS2?
