Gmaeshark codes not working on back-ups?

[darthsyth]

I have a magic 3.1, and try to use GS codes on my back-up games but the codes don't seem to work. Do GS codes don't work on back-up games? The codes work when I load original.

Gameshark codes do work with backups, however if your backup has a pal/ntsc selector or trainer codes will not work.
