I'm not sure if this topic has already been covered... I searched the site but could not find any info... I have a model 1 PS2, with a neo cube, dvd region x, unknown modchip, someone did it for me but i dont have a clue as to what it is, all i know is that it was opened and soldering had to be done... is there a way to find out what chip is in there? i've burnt backup PS2 DVD games but it won't play... do i have the wrong stuff? am i loading it wrong? i can play back up ps1 games, and back up ps2 cdr games... i just got a dvd +/- burner (pioneer) tried burning on both + & - disks but it won't play in the PS2, could someone please tell me what to do? thanks so much!
