Hey thanks so much for the help!
So after opening the save file in the hex editor, my save file seems to have two extra lines compared to the screenshot you uploaded:
So I wasn't sure whether to delete the last two lines, or the last 4 lines. I backed up my save file and tried both, but...
This is a long shot since this thread is fairly old, but I've been trying to transfer my save file to Crystal on the virtual console on my 3DS, but whenever I export my save file using VBA-M, the .sav file is always larger than 32KB.
Thanks in advance for any help.
