I have a PlayStation 1 with the GS port on the back, and I have that kind of Gameshark (not the disk kind). The gameshark has a sticker on it labeling it version 2.3. I was told that, by using X-Flash software, I could overwrite this sort of gameshark with a ROM that allowed backups to run without swapping. The problem is that, despite following X-Flash's directions, it cannot find the ROM. Any advice?
