So some games, like pokemon heartgold and phantom detective just freeze in some random spot. And when i plai that scene again it doesnt freeze. And after freezing when i boot my ds it says that there is no ds card in ds. Then i have to take off and put acekard back to ds many times before it starts working. Its rly frustrating when i have played long time then suddenly it freezes and i have to play everything again. Ps sorry for bad english.
