Since these are just #Emulated ISOs with no real work done to them, they needed to map emulator controls to the controller without interfering with the built in controls. So a bunch of standard options are baked into whatever left over buttons they had. Want to save? It's right analog click, which is just great when you're playing with a 2D retro controller from 8bitdo or retrobit with no analog sticks. You can't even exit a game without a stick, so once you launch one, you need to alt-f4 out.
