I have played Pokemon Diamond on a R4DS and I have decided to buy a official cart and put my save on it. (For Wii connectivity) Before I buy I need to make sure nds_backup_tool_wifi can properly handle 512KB saves? I ask because I know savsender only handles up to 256KB saves, so it is useless to me. Since even after I get the official cart I will make regular backups of my save. Or even trade the save between the rom and official cart. Also I assume their is still only one cart revision of the US release and I will not have to worry about save compatibility like with old gba fire red and leaf green where you had to get the right cart for the save or it would not work.
