I put it in dark green in the compatibility thread, after not being sure:

I am always kind of tentative about where to put things because somebody may genuinely want the DSTWO for only a few games and I might be steering them wrong. Still I do have an actual F-Zero cartridge and it doesn't feel like the worst thing in the world to play it on the CATSFC. Haven't noticed any REAL video lag. I'm not one that can usually tell the difference between FPS and stuff like that though. If I had a camera that didn't suck or a phone that didn't suck I'd take a video of it.
Here's what I said, anyway:
F-Zero – OK, seemed better. Only changes I made were the aspect ratio (changing from entire screen to entire screen, smoothed). I’m pretty sure this works fine, but I felt like I had more control while using the 3DS D-pad instead of the circle pad. This’ll be in dark green unless others have tried it and think it should be moved.
