Homebrew Replaying through tales of symphonia... cheats!?

[xtreme1]

so im trying to get my original disc of symphonia to use cheats... I plan on using the wiigator's backup gamecube launcher .02 since thats the latest i believe. Im having trounle though... I cannot seem to find how to use the ocarina function or find cheats that match my game... Can anyone lend me a hand?

I really just want to unlock the max grade instantly so I can restart my save with everything...
