I've heard that PS3 is region-free for blurays and ps3 games, which is great. However, it is apparently NOT region-free for PSX/PS2 stuff.

I want my PS3 to play Japanese PSX/PS2 games. How can I make it do so without a modchip? I've read that you can use an Action Replay on a PS2 to force American PS2s to play Japanese PS2 games. This is the sort of solution I'd like for my PS3.

Any suggestions?
