I've never used a gameshark before but I sill love playing the older pokemon games (red, yellow, gold, crystal) so I recently (after much research) bought one off of Amazon.com. It will be coming in the mail shortly but I was wondering if I will be able to use it for my pokemon emerald game? I usually play all the new and old games on my gameboy advanced (NOT sp)though I do still have a color. If I can't, where can I get a good gameshark for a regular game boy advanced? I guess i don't really need it but I'm kinda cought up in catching them all so if you have any idea, please let me know. Thanks!
