I just got the Supercard this week, and copied all my .sav files from my R4 card to the new one for my Supercard. I haven't had any isssues with R4 .sav files, only with Pokemon Pearl. It ignores whatever .sav file I have (the file names match btw) on the card. I tried deleting it and letting the SC make a new file, and I just made a temp save file and saw no .sav file was on the SD card. So I thought it didn't save at all, and when I started Pokemon Pearl up again it did show the save for the temp game. I tried to mess around with the different options but nothing seems to change. Any help you can offer is a welcome for the SC to play my older save.
