Steam.
Deck
Also some midrange phones with a external controller could do the trick but I have no experience with that
You might want to take a look at this retro handhelds spreadsheet. You can try filtering out good GameCube support (column S, support level A) and going from there. Good luck!
This is amazing, thank you!
Gamecube is old enough that a fairly mediocre phone running Dolphin should be able to do it.
I was gonna suggest this. Have you tried dolphin on your phone, OP? If it can run the games well, then just add a controller like the “GameSir Lite” for relatively cheap.
Might not be the absolute cheapest option, but a steam deck is a pretty great solution
And it’s also a steam deck.
Maybe look for second hand 64GB models near you if you’re on a tight budget, you can expand the storage with an SD card easily
NVME card replacement is also a cheapish investment. I’d recommend that over an SD card. My 512gb NVME was $50 when they were expensive
It’s definitely not a budget option but it’s arguably the most worthwhile for the cost.
Rg cube. But really a good Bluetooth keypad for your phone like a game sir is going to run better and be cheaper.
