Was debating on buying an Action Replay for the PS2,.

Does anyone already have one?

I wanna know if I can use it for PS1 games since they also work on the PS2.

Sorry to highjack your PS2 Action Replay thread, but I was just thinking about this last night for the GC. Both of these systems have such a strong base in Japan, and there seem to be alot of games that only come out there... are any of them good? Can we even understand them?
