tbh just play gamecube games on the wii. it’s easier to softmod and cheaper overall (have you seen the price of 480p component cables for the gamecube vs for the wii??????). nintendont + usb loader gx is a great experience too
the only reason i can think of to invest in gamecube as a platform is if you want to use the game boy player? which… it would probably be better to use a gba consoleizer instead
i guess the gamecube produces a (imo negligibly) better image (subjectively / to some people) but really it isn’t anywhere near the difference between a wii and wii u (where the wii u produces a noticeably darker and muddier image for wii/vc games) – and also the issue pretty much entirely stems from the filtering that the wii does + the aspect ratio it’s rendering at. just disable deflicker + enable framebuffer rendering in usb loader gx to close any gaps between the two systems (and hardmodding the wii for hdmi output should be even less of a difference)
so yeah unless you wanna use a gameboy player specifically then skip the gc and go straight for a wii
