Hacking Custom Gamecube banner music

[kbell917]

I hacked my Wii two months ago to play GameCube games, and I noticed a couple of them have their own custom banner music instead of the normal GameCube jingle (ex: live and learn playing for sonic adventure 2, vs mode menu playing for pokemon XD). From what I can tell these come from the banner downloads from gameTDB, however, I've been trying to find ways to add more custom banner music for other games like SSX tricky, Super smash bros. melee, and metroid prime, but neither here nor google has given me any answers. at least not for nintendont. is there a way to add my own custom banner music or find someone who can? or some software I can use to do it?

you only need CustomizeMii 3.11, ShowMiiWads-Mod-1.5.2, the original .wad extracted from disc and audacity for edit music
The music MUST be .wav mono and encoded 16bit PCM.
there is a good guide in this forum
