Large case of “you get what you pay for”, i assume. It has a gutted model of android and isn’t actually meant to do something outdoors of run the included apps. The {hardware} is actually not enough for emulating half the issues it says it will probably.
If you wish to try this in a non-jank method, you’re looking at one thing comparable to a barely higher android “console”, a telephone with a controller, a hacked nintendo swap (swap stuff + android, linux with retroarch, emulators on the swap OS).
