right i bought a ds lite in 2008 and it had the original r4 1.18 version and it DID NOT save ever and so i recently got a micro sd reader and updated it to the latest wood r4. Still DOES NOT SAVE :/ Before you ask, yes i have reformatted the sd card and checked for errors but it says the card is fine and not corrupt. I tried just changing the background of the start screen and even that doesn't save. WTH is going on?!!!
