Weird cross-platform homebrews

I can't remember a whole bunch of this one but I believe the premise was interesting.

In recent times (2022, for anyone reading in the future), there appear to have been developed some cross platform homebrews for the Gameboy Advance and the Gamecube, there wasn't a whole bunch to it besides that and the fact they had occultish names and banners, even though most of the applications I remember were basic emulators for other systems, one name that sounds similar to what I remember seeing was "Teoxida".
