So I got a DS lite off craigslist, and it has a weird problem. -Works fine with offical game cartridges, 50% of the time. Sometimes just turns off pretty fast. -Loads up R4 DS but then shuts off before a game can be fully loaded/you can do anything. What have I done? -Tested with it plugged into official wall adapter. -Tested with known good battery. (also official) -Opened and checked to see if they was any pins solder together on the cart connector (friend told me to check?) So yeah WTF? I am going to let it charge overnight and test it but... Whats wrong with this thing?
