i never seen such a close multiplayer mario kart thing usually one person is just infinitely better than the other but it was actually kinda close till the end
I want to 100% every Mario Kart, but the SNES cups on this one hinder me. You have to play PERFECTLY to get 3 stars. I have 3 stars on 50cc Mushroom and Flower, but that's it. Also, we should be VERY thankful that Super Mario Kart doesn't have Ranks. It's hard enough as it is. Mario Kart 64 is the easiest by far.
It is mGBA. The option you want is in settings>high resolution scale, and then set that as high as you can, although too high might make the game run slow, depending on what kind of computer you have. Video renderer needs to be set to OpenGL instead of software for this to work.
