this happens and also as a side effect the .esv file is unusable even if i try to extract the .sav using Goomba Save Manager,
if i try to extract using goomba save manager it says "error the length of the gbc data (8192) is too short - expected 32768 bytes.
maybe i can make a new save and just edit it to turn it into my old save not sure if it would fix the issue tho, i know it's possible tho.
pls halp
