I recently purchased a barely used PSTwo (slim). The the previous owner purchased it while deployed overseas (outside of the United States) it was purchased with a pre-installed MOD that allows playing of burned disks. I want to be able to run backups of my original games, preferably off an external USB drive. (I have been reading up on the USBAdvance threads.) Also purchased a used 32MB MAX memory card. It had several "corrupt" data files that were locking up my PS2 when I was trying to clear out all the previous save files. Since I was able to burn an ISO-> CD of the "ps2newz_mckiller" and it formatted my card (clearing the bad data). Seems to confirm I have a working MOD.. but any idea how to find out which one/what kind? The Model# on the back of the unit reads "SCPH-70012", but when checking the version information on bootup it says "SCPH-70011". Thanks in advance!
