I guess I could research but I thought I’d ask. I had a silver GC back in 2002-2004 and around 2009, my dork-ass brother mailed my GameCube to a friend across the country because he wanted to play an online game with him. Obviously I’m never getting it back, but I still have all the games and it would be cool to play them.
This is quite a late reply obviously but now I’m curious if you found a GameCube in the meantime.
I got mine from a local Telegram group where people sell used stuff. So depending on where you live, a similar platform might get you a good deal. I paid 40€ for mine including a controller which I thought was quite affordable.
At this rate it may just be cheaper to emulate them and use a GameCube controller adapter for Smash Bros. to use the controllers.
