Save File Decompressor

By DerKODerKO. Last updated



What is it?

Impossible Lair save files are compressed and are not readable by a human. This program decompresses save files such that they can be read and written to with your favorite text editor. After the desired changes are made, you can compress the file so that it may be read by the game again.



Source code:

Im not paying $75 to sign my executable with a certificate, so Windows will tell you its dangerous.
If your cautious:
1) Check the source code or build it yourself with Visual Studio.
2) Check the checksum of the executable before running it.
This proves that the .exe file I made is the exact same as the one you received.
3) Scan with Windows Defender, a good antivirus built into Windows 10

How To Use

Loading Steam Save Files:
Go to C:\Program Files (x86)\Steam\userdata\ and then there will be folder(s) with numbers unique to your Steam profile. In one of those folders, there will be another folder with the number 846870 which is the steam id for Yooka Laylee Impossible Lair. Inside that folder will be a "remote" folder where YLIL saves its save files as .dat files. The name of these save files are slot-patch-#.dat where # is the slot.

Loading Epic Games Save Files:
Go to C:\Users\You\AppData\LocalLow\Playtonic Ltd\Yooka-Laylee and the Impossible Lair, easily accessed by entering this into Run(Win+R): %userprofile%\AppData\LocalLow\Playtonic Ltd\Yooka-Laylee and the Impossible Lair

The loaded file will be decompressed and a new file with the name slot-patch-#-Decompressed.dat . Edit this file with your favorite text editor (mine is Notepad++) and then save your changes.

The loaded file will be decompressed and a new file with the name slot-patch-#.dat will be made or overwite the one that already exists. The changes you made to the decompressed will now be readable to the game.
