To boot into a game, add one of the remixed projects (if there ever will be any) into your backpack and add them here. There's also a test disc inside to show how to boot into their creations. It is literally super simple, just use the required scripts and instead of loading your game with the flag, load it with the "start" command.
I'm gonna make a boot OS soon, but for now, super simple. BIOS updates V1.0.0 - Lightweight BIOS created with boot screen and sound.
