FFVII codes.... what device do I have to use?

[Ichisuke]

So I would like to use some of these codes for the american NTSC version of FFVII (with an original PSOne)

I suppose these are all game shark codes but what game shark do I have to use? Do these codes work on any CD version or only on specific ones?

Thanks everyone!

If I'm not mistaken the gameshark CD's are all V5 which is also the last version of GS for PSX. I think any of those codes will work.

I made many of those codes with a later GS model for PSX. All the GS codes should work with any GS that has the capacity to hold'em all, or at least as many as you wanna use. I've never had trouble with them using any PSX GS, although it might be tedious to load each code manually.

(Thanx to all the others who made FFVII codes!)
