Have downloaded club penguin and put the nds file on the r4 card. Get a message "the save data could not be accessed. Please turn power off and re-insert the DS card." I tried updating the firmware, so am running with R4SDHC v1.25 English. Still no luck. Any other ideas? Should I try older firmware? I have tried downloading the game from 2-3 different sites, but with no luck. Hope someone can help!
Sorry but it is not the file, it is the firmware on your card, if you already have the latest then you can try to contact them to see if they will add it to the next update
