He has a cyclo ds for his old ds (which is now smashed and sent away thanks to me). He got a dsi today so I need to order him a new flash cart. I think I've decided on the DStwo but how much trouble will it be to transfer his cyclo ds save files? Does the firmware (or whatever other files are necessary) take up more room than the cyclo ds firmware/files did? His sd card is nearly full. Also what about moonshell? thanks! I've been doing searches and reading but my mind is fried right now with all the information.
