>>712908746 (OP)I strongly recommend the Deck OLED.
I set Emustation in January, then cleared
>Punch Out (actually I stopped at Super Macho Man because I'm a wimp)>Punch Out Wii (stopped at title defense Sandman)>AW1>AW2>AWDS>AWDoR>Metroid 1 (which I do NOT recommend)>Metroid 2 (which I do NOT recommend)>Metroid Fusion>Metroid Zero Mission>AM2R (this one I had to put it manually into desktop mode then add it to Steam)>Samus ReturnsAnd there are a few more I'm probably forgetting.
Also I just bought the Castlevania GBA Collection, and the sound was fucked (I think this is a Steam Deck issue). Went to emulation, and everything is perfect. The screen is amazing, the controls are great, I find it hard to complain about anything really.
