Is this a common issue, or could something be wrong with mine? I'm certain that it's not a fake. I have an R4 (real, original) in addition, and that saves much faster. I switched to my DSTT because of compatibility issues. I tried YSMenu on the R4, but I had some sound issues in a few games. The DSTT doesn't have any sound issues with YSMenu, but it takes significantly longer to save. It's not a dealbreaker, but I'd like to fix it if possible. The long save times occur on both the official kernel as well as YSMenu.

Just for comparison, it takes 8 seconds to save in Pokemon Mystery Dungeon Sky on the DSTT, and 3.5 seconds on the R4.
