I recently bought an AceKard2i along with a Sandisk 4GB MicroSDHC from RealHotStuff. Everything seemed functional, but after downloading some games, I had found that certain games were extremely laggy to the extent of being unplayable. My brother has a R4DS with a Kingston 2GB SD also from RealHotStuff that seems to have no problems playing any games. I have searched around the forums but have found no solutions. Problem Games: Rhythm Heaven (Lags insane amounts while playing the second game.) My Japanese Coach (Extremely unplayable lag right from select screen.) Rune Factory 2 (When there are more than 3 characters on the screen, it starts to slow down.) Mario and Luigi - Bowser's Inside Story (Unsure, random times) I can bare with Rune Factory and Mario and Luigi, but the rest is simply unplayable. I am using AKAIO 1.8.1 on a NDSL and have formatted my SD card with SD Formatter. Help?
