1) reply in the same thread - don't keep making new
2) I have just deleted my system file and it does say (white letters on a black screen) no system file found, put system file in.
The system file should consist of a single folder called SYSTEM, the whole folder goes on to the card - not just the contents. Re download from the link I gave you, unzip the file, put it on the micro SD
Create a new folder on the micro SD - NOT in the SYSTEM folder!, call it NDS - put the roms in here, Need More space add another call it Brain Games or anything else you like.
1) No more than 127 roms per folder
2) Leave at least 1MB of free space per rom you add to the card (100 roms = 100MB free space)
All roms must end in .nds, so they must be DS roms and unzipped
