Dual Boot

1. The RG552 is a dual boot capable system with Slot 1 used to store linux firmware.
2. If Slot 1 is empty it boots to Android 11 hosted on internal 64gb storage.
3. Slot 2 is used to store roms so either OS can access games.
4. Some say android has better gpu performance but in my testing I don't see the difference
5. Still since android is more flexible and now supports much better front ends I think we should go with that

Front Ends

They ALL run on Android 11 64 Bit on the RG 552.

Vertical Layout

To enter vertical layout must press top custom android menu button by swiping down from top of device. This is the same cluster with fan control and cpu OC. This device cannot sense up and down. I guess doesn't really matter as this is not a phone. Controls on this device would never work in vertical layout anyway.
