There’s a flatpak in the discover store called AM2RLauncher. I installed that and right clicked on it to add it to steam. You have to also have the am2r 1.1 zip file.
Once I had it in steam, I used the SteamGridDB plugin to give it some artwork. The in game controls didn’t automatically work with the steam deck gamepad, but if you go to community layouts and hit “show all” there will be at least 3 that change the deck controls to keyboard inputs that do work.
One other note is that the default binding for missiles is control, but for some reason holding control seems to be blocking other inputs preventing you from firing missiles. This could probably be fixed by changing the key, but I instead changed the in game settings to make missiles a toggle ala super Metroid, and that fixed it for me.
