Probably a good idea, I don't think most people are familiar with the actual events. I know I personally only ever used gameshark to cheat the item in and not start the event. Don't be discouraged though, this is something I've been looking for for at least 7 years now, I just wish there were more wonder cards available. Do you want me to test all the .me3s in the folder or just the ones I see on the DS version?
Also, as something pedantic: on the change cart screen on the NDS version the US spelling is ruby and sapphire, rather than rubi and saphire.
