I decided to give YSMenu a shot since it seems like it will become more necessary considering the lack of R4 firmware updates in the future. The way I understand it, YSMenu allows the R4 to keep up to date when it comes to playing newer DS games. Now, I tried playing a few games that worked on the official R4 firmware and they wouldn't work for me. I would get a "ttpatch debug screen." After going through a bunch of steps, it gets to this part and stops: write reload bins... make indextab...disk errcode=-21 47483632 system halt! Why does it do this?
