I have a Ps3 and as far as I know it only comes for Ps2 and 3s aren't backwards compatible

Launch-model Fat PS3s are backwards compatible iirc

20GB Fat Launch models to be specific

oh, I've got one of those fancy 250GB Super-Slim models so I guess I'll be missing out on this as a speedgame

Do you have a gamecube or wii?

I have a wii but no gamecube controller FeelsBadMan

Then I'd highly suggest looking into getting one, the game itself is cheap for Gamecube versions, and Gamecube controllers used aren't tooo bad of prices.

I would not suggest getting the 2-7 dollar unofficial gamecube controllers.

I don't have a Gamecube controller because I hate their design and playing with them in general

welp

Try different 3rd party controllers? There are some that do wildly differ from standard controllers, maybe even get some kind of adapter to take a different controller to be compatible with gcn ports.

Otherwise, dunno what to tell you
