you would be better off using codebreaker tbh
anyways, would you mind to try a different config? it will make a savedump instead of saving the game as usual.
just in case better make a backup of your save data and make a new memcard image with only your tota savegames. then just load your last save and then save again. it will create a savedump and probably will fill up your memcard image.
then just upload the decrypted memcard image or only that savedump to a hoster and send me the link

using cheats in config works fine, as long as the elf file doesn't get compressed when loading from memcard in combination with codebreaker. thanks for the explanation on this
