Chrono trigger but how???

I have a Chrono trigger rom and I want to play it on my PSP. Can someone tell me how and what emulator i need? Thanx.

UO is the fastest/most tweakable releason and works with Trigger but games like Super Metroid, etc do not work with it. It will not be full speed though, u have been warned. But UO is the recommended one.

Ok, I have put the emulator onto the memory stick and the psp reconignises it. But which folder do I put the ROm in?

In the same folder where the eboot is for the emu.
