I have found an easy fix to get some stubborn games to load...My Daughter has a DS Lite and had a game that worked fine. That same game did not work on my other daughter's DSill. I took the .sav file from the working DS lite and put it on the DSiLL and it worked! They where both R4 cards just different Versions... My Daughter has Bowsers Revenge and Wheres Waldo....Please I am look for anyone to e-mail a .sav or send my to a sight that has .sav files. This is a real good fix and I am shocked no one ever talks about it.
