Out of curiosity when did he mention a 360?Since when are you able to play Xbox 360 games on your 3ds
i think the save bug is more related to the SD card your using for the 3DS, i used b1 for ages and virtually never had the bug, maybe twice in total but i think it was once,
recently i decided to give b1 another test on a different SD card and it kept crashing on startup or hanging when saving, so i tested again on my original 4GB that came with the 3DS and it worked perfect again, i don't know why but it just seemed to dislike the other SD card
the one that didn't like it was a 2GB that came with the standard 3ds (think its Toshiba) and the 4GB was a LexarInteresting. I was using the PNY SD card that came with the 3DS. What kinds were you using?
