Its awesome. I just tested it on the 2.6FW and it works great. I tried The Legend Of Zelda - The Mintish Cap. It runs slightly slow, and the sound is abit screwed, but its so close to being perfect. Runs pretty well, nice presentation, and you can exit the emulator by holding L & R.
Just think all those great games like Mario Kart and Advance Wars we would be able to play at full speed. All it needs is abit of tweaking and it will be perfect. The only problem is, the last release was over 6 months ago, and the author has stopped work for whatever reason. the source code has being released though, and can be downloaded from that same page i linked. Anybody up to the challange? I would but wouldn't have a clue where to start. LOL.
