libogc vs gba booting

While I have no plans on actually trying it (partly since I don't own a gba), I am wondering if there is any support for sending executables over that GC to GBA connection cable. It's a bit obsolete, but I think that it still should work on a Wii, and I am sure someone have used a normal GC game that did this.

Yes, I know of 2 games that do this (I own them)
One of them is Animal Crossing. If you had the GBA connected, you could send your villager to a secret island (on the GC) and it would give you a map thingy on the GBA (I think, haven't done that one in a while.
Another one is Sonic Adventure 2 Battle. You can send one of your Chao's from the Chao garden to your GBA, and it gives you basically a Tamagotchi on your GBA, that you can transfer back to the GC to save what you did.

Maybe someone can reverse-engineer this protocol, so we can send GBA homebrew to our GBAs with our Wiis =P

Yeah, that is what I wanted to hear about, sending homebrew and so on. Of course, I have searched, but it's been result less since I haven't managed to think up the right keywords.

I know no$gba emulator has support for this, sending gba executables over a link cable (connected to pc via parallel interface), try checking the no$gba docs?

Ah yes, good idea GizmoTheGreen, however I see a problems with that: NO$GBA uses an Xboo cable, which almost definitely doesn't have a similar interface as the Gamecube Port -> GBA adapter. However, combining those docs with some way to transfer raw data TO the gamecube port could yield some good results.
Too bad I'm too lazy to do it myself XD

Have a go at it, henke37, see what you can do!
