You know the anime fighting game called Valkyrie Fight Tag? Well I have that game on my PC and it's EPICALLY COOL! I was hoping someone could port that game to the Wii. And then use Gamecube controllers to play it.

Is it open source?

I don't know about open source. But I DO know that it was home made (not made by any game company). Home made games are usually opensource (unlike professional made ones, which tend to be closed source).

Well, you'll need to find out what language it's in and if its open source. Otherwise, no one will help you.
