Tutorials
Preparation
GBC, NES and SMS Emulators
Arduino
- How to write a code?
- References for control the board.
- Application notes.
Trouble shooting: Force exit emulator or recover from a non-responsive emulator
When emulator keeps crashing due to the ROM compatibility issue, there is no display on the screen even though the LCD backlit is on.
In that case, you have to use “Menu” button to exit.
Power Switch Off, Hold Menu, Power switch On, Release Menu when Main Menu appears
