Do PSX Backups require a GS2 to play?

[ryan0123]

When did I ever say anything about buying the chip to play a Japanese version of FFX? I know it's already out it the states, _I own it_

The reason I'm buying the chip is to play PSX backups! See, I never owned a PSX, I had a N64 for quite some time, and I enjoyed that, but now I want to play some of those old PSX games that I never got to enjoy, most of them are impossible to find nowadays (i.e. Xenogears.) so the only way to play it is to download it!
