These appear to do the same as a gameshark, and are cheap as dirt (at least the one I bought was 1.50). Not sure how well it'll work though, I can't use mine (I have a PSOne).
This is exactly what breaker pro 1.1 does, loads up a menu like that (minus the cheats bit) stops the disk spinning and allows a backup to be inserted. Since you say you "cant use yours" can i buy it? hehe just a thought, if not i'll go search for one of these as well as on more gameshark info.
