I'm using a NTSC-U PS3 and want to play NTSC-J PS1 games. I did CEX to CEX and change my PS3's system Region to Japan and everything worked however when I put in my copy of Metal Gear PS1 import it says it's the wrong region.
BDVIDEO Region A(USA),B(UK) etc
BDGAME Region Zone 1, Zone2
DVDGAME Region NTSC-J, NTSC-U
DVD Region 1 USA 2 UK etc
CDGAME Region NTSC-J, NTSC-u
Now I don't want to play any backups since I have the original discs. I have a theory but I don't know if it's possible. To remarry the drive with the system so the EID is check and the drive is flashed with the correct region. Has anyone confirmed or tried this?
