@VictimRLSH I tried the exagear demo on a "sandbox build" image of my regular gaming build. It did work fairly well, but it seemed like the install was too deep rooted into the system (just try fully uninstalling vs you'll see what I mean). I ultimately decided to not purchase it mainly because of their business model. Doing some research, It's closed source, which is okay if they were really vested into maintaining exagear, but the number one thing is the liscence is tied to the specific Raspberry pi you register it on - so when your board dies or you upgrade from 3b to 3b+ you must purchase a new liscence.
If the license was, let's say, $5 it may justify that bussiness model. It's a shame, they have something that would otherwise be huge.
I've been using a custom compiled wine through raspian to play Diablo 1, Diablo 2 with Lod expansion, & Starcraft Brood Wars. (Bonus - net play co-op) Unfortunatly, it required someone to compile the game..exe for arm but maybe with enough support they can get wine fully implemented to work just like exagear.
