Jjust a warning to everybody, ive been using Rudolph's NDS backup tool quite a bit lately with my r4 and ez flash 3 in 1. great tool and generally works great, but a warning based on my recent experiences: backup in general is a good idea, but make sure to backup important stuff (saves etc) especially bevfore using this tool. When dealing with signle files it seemed to be ok, but lately when i was dumping 5+ saves or games in a row, it consistently created corrupted data in the NDS_BACKUP folder which eventually led to corruption of my entire card after running the tool again. Its happened 3 times now. The last two times i reformatted immediately after getting the corrupt data, but the first time it corrupted my card so bad that neither my computer or r4 would recognize the micro sd. only my digital camera would. just be careful, and in general remember to backup your saves!!
