I recently received a supercard dstwo from the affiliated shop and am currently very please with both the card, and the shop I got it from. I have one problem though. While all of the games have worked perfectly so far Advance Wars Dual Strike while working causes the DS to play up in sleep mode. If I shut the lid both screens flash white over and over in sucession. Also the battery slight flicks on and off at the same tempo while the speakers emit a sound of slight static sound at each flash. The tempo is around 2-3 beats per second. This continues until you open the DS again, at which point everything is perfect as if nothing happened. This is on a DS Lite and I only have it to test on so I don't know if it effects others. Thanking everyone for their help and if it'll help I'd also appreciate finding somewhere to find a bugreport if need be.
