hi oscarleo
here is some tips: When power on your NDS , hold ONE button UNTIL the game start to run:
don't hold any button and power on - use MK4-mini NDS Mode #1
hold "L" and power on - use MK4-mini NDS Mode #2
hold "R" and power on - use MK4-mini NDS Mode #3
hold "B" and power on - use MK4-mini NDS Mode #4
hold "A" and power on - use MK4-mini NDS Mode #5
please try it and see it can help the non-work games or not
