[quote name='YoshiFan1']I'm really not sure. I never used them and don't know anything about them. The only reason I know they exist is a few years ago I saw them on BestPrices.com (I don't think they still have them on the site). I was going to get them but since around spring 2000 when I got Excitebike 64, I haven't really used my N64 except on car trips so I didn't think it was worth getting since I would never use them.
Here's an auction with a picture if you want to see what they look like

i was really excited when those controllers came out for n64, but never got them since they were so expensive. i do believe these controllers function on infrared and not radio frequencies like the wavebird or logitech controllers. Meaning, you need to aim the controllers at the sensor in order to get them to function.
on another note, i have a wavebird and a madcatz lynx controller for xbox. the wavebird is simply the best controller i have ever used. the only downside is with fps or shooters in general, which are not huge on gamecube, but still the layout isnt great for games like metal arms. this is true of all gamecube controllers though. otherwise it is flawless. the madcatz controller is also very good, but has some flaws. it uses battery life much faster than the wavebird(about 4-5x as fast) and requires 3 batteries. also, it does not have an off switch and supposed to have an auto shut off, but that does not work very well, so i tend to turn one battery upside down, and it is a slight inconvienence, but nothing major. the controller functions extremely well and i never have a response problem, unless the batteries are dying. it is about the size of the original xbox controller, with the same layout, but i like it much better because of a slight form factor improvement and great grips. i highly recommend the wavebird with a 9.5/10 rating and the madcatz an 8/10.
one other thing to think about is using a converter to use a controller from one system on another. i believe there is a converter for dreamcast for a ps2 controller. i don't know if this will work, but it is something to think about.
