i have a gameshark for the original playstation and for the GBC. the gameboy one messes up the games sometimes (darn cartridge games!) and...... i guess the playstation one kind of messes them up too! it was a lot of help on most of the games only i couldnt really figure out how to add games. they cose a decently good sum of money so if you want one start saving, i think it is worth it.
