For Roblox, there's Sober. It works (IIRC) by putting the android version of Roblox in a container and passing the appropriate system calls to the Linux machine. It doesn't need to worry about issues with Roblox's Byfron anticheat since Byfron hasn't been implemented there (yet).

I wish microcenter opened more locations. From what I've seen it's essentially a modern day radio shack, but they have only 25 locations (in only 16 states!), and none of them are in my state. They do sell things online I guess, but they just aren't as competitive online compared to their physical stores.
