what is a nds loaded that that will work without flashing the firmware and let me play games and stuff from my card in the ds slot1?
if you want to play games from the slot-1 of the ds, you need to buy an adapter like the m3 simply or r4. those use micro sd for memory and its just click and drop. put the games on micro sd, then put the micro sd into the m3simply or r4 and put that into your ds slot-1. turn on and play. no neeed to flash the firmware, which is better cus there is no chance of bricken then.
It's not exactly drag and drop with the M3 Adapter but it is pretty easy. You will have to use a program that is provided to convert your DS and GBA roms. It is quick and easy, takes about two seconds per rom.
actually, if it is the m3 simply or r4, it is just drag and drop. you are talking about slot 2 devices. the only program you need to use for m3 simply or r4 is rom trimmer, and that just makes it smaller
