Jazz Jackrabbit Save

This project aims to reverse engineer the process of reading and writing Jazz Jackrabbit 1 SAVE files.

Acknowlagement

It can read (decipher) and write (cipher) SAVE files at this point in time, however there are still some unknown values.

The current cipher function code was created by analysing instructions and registries dumped by DosBox-X using the LOGL command, and manually translated to C and optimised later.
