I used the Sunshine game streaming software and the WiiU homebrew port of Moonlight to get game streaming working on a WiiU gamepad. It’s sort of like a bootleg Steam Deck, and it works surprisingly well, but it mostly just made me want a Steam Deck.
It’s a fun little hack! I like how it’s alllllllmost practical, but not quite :-) The biggest limitation for me right now if that I have to stay within 10 feet of my WiiU console or it has a bad time.
Idk if you have one already, but the Wii LAN adapter helps a lot with latency and bitrate. It won’t help the limitations of the Wii U Gampads poor Signal strength, but its something :P
Also, moonlight works pretty alright on the 3DS and Switch if youre looking for more projects lol
If you can’t find an original adapter, I can confirm this one works. Most of the other ones I had laying around wouldn’t work. I had to search for this one. It was only $15 when I got it in January 2025, not sure why it’s $25 now
Its any Ethernet adapter with the AX88772 chipset. I would also go for getting it from any other online seller :P
