there's a tutorial in my tutorials or @KiiWii 's aio thread. you basically just have to mount the game save, which iirc appears in mnt/pfs , then ftp it to your pc (remember to unmount or the save will be stuck in limbo with no way to delete it unless you rebuild the database), then you do the same for a new save, and replace the files outside of the sce_sys folder. don't touch the sce_sys folder at all as it contains the account id in the param.sfo (offset 0x15c iirc in little endian, so it's byte reversed).How can I resign the save, do you have a tutorial ?,
Thanks
With save mounter, yesEven if it's other account for the save ?
