Turn off your DS system and start the game.
Turn it off then turn it back on

TurN it on than off
that happen sometimes... easy fix just press the home and power buttom at the same time for like 2 minutes
U do it
when the DS is off hold A and B when u turn it on hold select and start and A and B until the list has ended then release
Take the battery out and let it cool down
Try running it on VMware
just go to a electronic store that you bough it from and get it fixed
I have Samsung tablet screen flashing and cannot turn off
Most likely a problem with the RAM. No other option , you have to get it changed.
