I recently bought a nip model of PS2 fat (SCPH-35000, NTSC-J) through ebay, but I'm having issues to read games that use Disc Compact discs (all PS1 games and some early PS2 titles like Phantom Brave & Kingdom, EDF1, Growlanser 2 & 3, La Pucelle, etc) while the DVD-rom discs run all fine. The console has difficulties to recognize the Disc Compact on startup, and it takes a couple of retries to have the console recognize those.
I was wondering what part I should replace, and if it's possible to swap the part from a PAL model or something, or if I have to rely on importing the detached parts.
