Valve's Steam Deck community hasn't wasted any time getting all sorts of emulators up and running on the system, and this is perhaps the most impressive feat yet. It seems Game Boy Operator and the Operator app are now compatible with Steam OS.

It follows on from a look at the Steam Deck running the GameCube and Wii emulator Dolphin, and also successfully emulating Nintendo Switch, 3DS and Wii U. There were rumours earlier this year about Nintendo testing Game Boy Advance games for the Switch Online service, but so far there's been no announcement.
