Yeah I know about download stations.I downloaded a whole bunch of em and put em on my cyclods evo. I have three ds's so if it isnt hazardous I could do testing. But heres the thing that makes me think that it is possible. When the rom boots up you can eject the cylco ds and it still runs. So I assume it is stored on the little bit of ds memory. And if you use a ds lite to broadcast to a dsi I assume the dsi can handle slightly more memory?
