Yep, Actually Mario Kart GP 1 & 2 are both fully playable on the Wii. Crediar released quadforce v0.1 a few weeks back that allows both games to be loaded via a DML'esque GC/Triforce loader. Unfortunately he became butthurt when someone(s) leaked a previous private build of it on the net and isn't going to update the Wii version at all. I dunno when these devs are ever going to learn.
He's apparently taken an interest in getting things working in the Dolphin-Triforce branch build now though, which is cool. MKGP2 is the only fully playable Triforce game atm in Dolphin. I'm sure that MKGP1 and FZero aren't far behind though.
I actually figured out a way to kill that annoying as Heck announcer in MKGP2 by modifying the .iso file. Apparently there is a much easier way in Dolphin though. I think its a simple dword patch that gets it done in the game config menu.
I'll be waiting on updates on the status of Dolphin before I commit to a cab build as things are still a little buggy, gameplay is smooth as silk though once you're actually in game. Anyway I've got my fingers crossed.
Anyone interested can check out the Triforce build and info here:http://forums.dolphin-emulator.com/show ... ?tid=23763and if you need help finding the games to go along with it you can like... erm, PM me or something. If I like you, I might reply.
