Well, its got the same dimensions as the SNES Controller (Compared it to my SNES Mini Controller), but also the same formfactor, so maybe not that ergonomic as a XBOX or PS Controller whit it horns, but it feels for me quite good, and i did allready 2 Test Sessions on the Steamdeck whit lots of different Game Genres via Emudeck, worked best for 2D Stuff, but you can also play your PS2 and Gamecube Stuff as long as you dont need the Analogue Shoulderbuttons..
On Weekend i try to pack it in my Switch Case, and use it also for Switch Games, and i want to make a Video whit it playing Emu EX Alpha + on the Pyra whit Bookworm..
Allthough these new 8Bitdo Controllers EvilDragon showed in his last Video where maybe much better for my purpose but i have now this Controller..
