I grabbed a couple of roms off a friend to try out recently, but for some inexplicable reason, they all have the suffix .dsg following after the .nds extension. Needless to say, I'm a R4 owner - the roms I received were from a slot-2 Supercard owner - is there anyway to restore the roms back to plain old .nds for use on an R4? Before anyone asks, yes, I did try changing the extension, by deleting the .dsg . Didn't help one bit, since the rom refused to even load. So... any idea?
