So I exploited my PS2 today using the Agent Under Fire method.

What I would like to know is if it's possible to use any of the apps to change the region of my PS2 from PAL to NTSC-U or J.

The reason I ask is because I'm really getting into Gran Turismo 4, sadly progressive scan and 1080i modes aren't supported on PAL systems. I would imagine the code is still in the PAL version (?) and surely tricking the game into thinking it was running on a different system would fix this.

I don't want to acquire a 'back up' copy as I'd rather stick to retail.

True? If so is there anyway I can go about doing it.

The Freeboot configurator has an NTSC option but I think this is just the menu's video output.

Please help.
