TIL that you can play GBA games with the Wii Remote.

It kinda seems like you can't because of the pop-up, but I noticed that the pop-up warning you not to use a Wii Remote was more of a suggestion than a complete requirement. So for shits and giggles I kept pressing it and it let me do it with the Wii Remote, warning me that not all the buttons will be available.

In Super Circuit though, this is manageable since you can kinda change the controls to get it to something akin to Mario Kart Wii, and I don't even know what the select button does in it. You should probably assign the least used button to the VC menu though, so you don't have to get out a regular controller later.

Doesn't acknowledge the Nunchuck though for some reason. That would've let me use all buttons on Super Circuit.
