so stupid me, i just now tried the thing with the charger plugged in with a game boy advance game and it works perfectly so it prolly also works perfectly with ds games... BUT when i listed this I was listing so much stuff (busy in a rush) and also i have never owned a DS and didnt realize (until now) you can play GBA games on it... so now with only 4 hours to go i find the system works perfectly but i cannot edit my listing cus ebay wont let me cus not much time is left! I am worried this is going to end too low now.. Help me out thanks!
