I have a flashed american DS-Lite with an m3 sd-lite. My friend has a regular DS. I know that download play does not work all the time with a flashed ds and a non-flashed DS. However, I was reading that some games do work. Can anyone tell me which games do? Also, will this matter if we are using different firmware? Also, I remember seeing a chart that had four possibilities of download play, where one DS was flashed and one was not. It explained the outcome of each scenario. I am having a difficult time finding that. Does anyone know where to get it? It must have been in an FAQ of some sort.
