It looks really good for a GBA game, but that camera is awful.

Wow, I never knew a thing like this existed. As you said, it looks pretty good for a GBA game, but the camera looks pretty terrible. (Probably because it was a tech demo back then)

It looks pretty nice for a GBA game. The camera is pretty awful though and you think this would have popped up years ago.

Is this real? It kind of gives me some fan-made vibes.

Either way, the camera looks slightly annoying, but otherwise it definitely looks pretty good. I like the music. Is this tech demo from before Super Circuit? Or was there a planned sequel and this was it?

Interesting. I never knew this existed before. It doesn't look that good to me, it looks rather bland for Mario Kart. Of course it's a prototype so I guess it'a alright for one. I agree the camera looks bad. Mario looks clay-like up close, it may be a style but I'm unsure, it's nice for GBA.

That camera looks pretty bad, and why does Mario look so strange?
The Graphics are pretty good, but something isn't right.

I think this demo was after Super Circuit, because the titles screen uses images from Double Dash!! 

Though, I don't think this was meant to be another game, just a tech demo, I think.

Huh, that's odd if so, it may just be a tech demo, but it's weird that they'd go back to Mario Kart even though a new Mario Kart title was already released on the GBA.
