The Gemei X760+ is pretty much the same as the Dingoo, but in another shell. Games compiled for A320 will work without modification on the X760+, however there are a few differences that could be good to think about.
1. Number of buttons
The X760+ doesn't have the same number of buttons as the A320. It does not have the shoulder buttons / triggers (L and R), Start or Select. Two buttons have a different label aswell, but those have no difference when doing the actual code.
The X760+ Triangle is the same as the X button on the A320, and the X760+ X is the same as the A320 Y.
2. Sound volume
The X760+ has a sound volume range from 0 to 100, while the A320 has the range 0 to 30.
One way to overcome the problem of less buttons is to do combinations of buttons. One example is that the power button is usable (it is usable on the A320 aswell). The power button can be defined as:
#define CONTROL_POWER 7
