One more step: this save has to be re-signed
Your file downloaded fine. But this save was written by Ren'Py 8.1 or newer, which
signs every save with a key that lives on your computer — and editing it breaks that
signature. Load it as-is and the game will refuse it without saying why: you click the
slot and nothing happens.
Signing it is free and takes about a minute — the Repack page asks for the file you
just downloaded and your security_keys.txt, and hands back a save the game accepts.
Editing Ren'Py saves often? Any paid tier stores the key once and signs every
download for you, so this step disappears.
