Ive got a R4 card and now and again certain games say they can not access the save file. This is so far international track & feild, viva pinata & imagine teachers. Does ne one know how you get past this. I have downloaded them numerous times from different links, ive tried clicking ignore when u load the game for the 1st time as well but still comes up with the message. Oh n Ive made sure i got enough memory for the.sav file.
try updating the firmware, goto the r4 website for download. r4 is never very good with new game release compactibilty, either stuck at loading, blank screen or sav file troubles. other flash cards are better at it, such as Edge, EzFlash, Acekard, Supercard DSsone etc etc.. go here for list.
