That's very strange then. Unfortunately I don't have access to the log because the entire SD was corrupted. Only thing I could get was this screenshot, seems like the onscreen instructions somehow got dumped into a few large files.
EDIT: Decrypt9 threw a warning about the AGB save being empty...
Is there any way you could upload the compiled Decrypt9? I'm a complete noob and I have no idea how to build it, but I'd like to use the save inject feature! Also, where did you locate your slot0x24KeyY.bin?
