So how does one convert an EZ Flash 3 save file into an EZ Flash 4 save file? I've bought two EZ Flash 4's for NDS execution and want to revert the EZ Flash 3 back to being a GBA device. But my son did have some working NDS games on the EZ flash 3. I want to get the saves for those games over to the EZ Flash 4. I know I can rename the EZ flash 3 .sav to match the name on the EZ Flash 4 but the biggest problem seems to be either the size or the format of the EZ4 save game. Whether I do a straight copy or try to pad the EZ3 sav file size out to 256KB, the EZ4 doesn't recognise it as a valid save file. Is there a conversion tool or otherwise simplistic conversion method or do I have to tell him to start the game again from scratch?
