On my 3ds I had no problems but on my 2DS the CIA's are taking forever to install or not installing at all. in bigbluemenu It takes hours to install any file over 1GB I just power off its rediculous. in fbi the cias are normal speed to install but they jam early on, like 5% to 15%; forcing me to hard reset. I can transfer the cias on-to the sd card from my pc in normal speeds. does this mean my sd card is messed up?
