Why is this? I have an R4, a DSTT and an Acekard 2i. I can unfortunately only use the Ackeard 2i at this point. But when I had the DS Lite, I noticed that the R4 saved much faster. My best example is with Pokemon Mystery Dungeon - Explorers of Sky. It would take ~4 seconds to save on my R4, and 6-8 on my DSTT and my Acekard (running AKAIO), causing significant slowdown (the music lagged noticeably) when it did so. This happened no matter what the settings were on my Acekard/DSTT as far as DMA goes. It also occured on my R4 when running YSMenu, but did not when running the official firmware. Lastly, my Acekard 2i and DSTT saved much faster when on a smaller but slower MicroSD card (1GB but low quality compared to 2GB but high quality, the 1GB saved faster. And yes, I tested the speed and the 2GB is nearly twice the speed of the 1GB). What could this be an indication of? Is there a fix? Or is it just normal behavior? Summary: Acekard 2i with 1GB card: 4 seconds Acekard 2i with 2GB card: 8 seconds DSTT with 1GB card: 4 seconds DSTT with 2GB card: 8 seconds R4 with official firmware: 4 seconds all around. R4 with YSMenu: Same behavior as Acekard and DSTT.
