Ok everyone, I just got a bunch of off-brand PS1 memory cards. There's a bunch of them that are marked "Super Memory Card 8000" and I thought I could cycle through the pages like you can with the Nyko 8x. It's not working though. Does anyone know how to change pages on this thing?

You probably can't. Many of those Memory Cards were fake and didn't do anything apart from corrupt you game saves.
