So here is the situation: A few years back I got the R4 Revolution for DS cartridge for my original Nintendo DS (Phat), along with a 4gb Kingston microSDHC memory card. I know there are compatibility issues with the 4gb cards and the old R4s, but it was working perfectly fine on some unknown version of a ysmenu firmware. In a moment of stupidity, now years later, I decided to update my firmware which resulted in failure. I have tried everything I can do to get a working firmware onto my card, but to no avail. It always gets stuck at the first "Loading..." screen. Does anyone know of a firmware and all the files I will need to get my card working again? A tutorial on installing everything would be very helpful. Thanks in advance.
