They will be stored in /extsavedata/SDMC and /extsavedata/NAND respectively. Also redirect some APT_A functions to their APT_U equivalents. Implemented the gamecoin.dat file in SharedExtSaveData in the PTM module. Implemented formatting the savegame. Retake a previous savegame if it exists instead of reporting them as not formatted every time a game is loaded.
