Can a Pal PS3 play kingdom hearts 2 final-mix?
It doesn’t matter if a PS3 is region free. PS2 games were not, and PS2 games don’t run on the PS3 software… they run on the PS2 emulator installed on the PS3 (assuming you have a PS3 capable of playing PS2 games at all). So regardless of the PS3’s lack of region locks, PS2 region locks are still in place. So short answer… no, it won’t work.
