Hey there, I recently bought myself a R4 and I'm loving it it perfect no problems at all. I was looking into getting some save files for a couple of games specifically Jump ultimate stars. Now I found one on Gamefaqs which was in .duc format. I though i could use the save converter on the cd I got with the R4, I did so and renamed it to the rom but when i ran the game it treated it as a new game. I've probably made a mistake somewhere but not sure where as my knowledge of save files isn't that great.
