Octogeddon Hacking Information and Hacking Tools

• This is a repo containing hacking tools and hacking related files for Octogeddon

Where are save files stored?

• Save files are stored into two locations which helps prevent hacking / tamporing.
• You need to either edit both save file locations, or delete the save files from one location and using the other location each time you perform edits.
• %appdata%/Roaming/Octogeddon/
• Steam/userdata/525620/remote/

Save file format?

• The original version of the game uses a octogeddon.sav format.
• The update that came out 10th March 2018 changed the save file format, there are now two files: octogeddon.sv2 and octogeddon.sv2x
• The octogeddon.sv2x as of now can safely be deleted and doesn't seem to affect anything, however, a backup should be kept just incase
• The octogeddon.sv2x file is simply a octogeddon.sav file with a checksum added to the end

Hacked Save Files

• You can find various hacked save files in the "HackedSaves" directory. These should be installed into the save files directory.
• EverythingUnlockedUltimateStart This is a save file with the game beaten, which unlocks Hard mode and Endless Ocean. You'll also start out with unlimited money when you press "New Game", and you'll be able to add an infinite number of tentacles to your Octogeddon.

How do I edit my save files?

• The online save file editor is available here
• Simply load in your save file, make the changes that need to be made, and then download the modified save file
• Make sure to delete old save files that are in both locations, per above

How do I unpack data.ayg?

• This repo contains a tool to both unpack and repack the data.ayg file! The tool can be used to both replace existing files in an archive, and build a brand new archive from scratch!
• The tool is written with NodeJS so make sure you've downloaded and installed a copy.
• Copy your data.ayg file into the Unpackers directory and then run unpack.bat to unpack all of the files -- This will create the extracted and edited_extracted directories.
• Copy any files you wish to edit into the edited_extracted directory, making sure that the exact path matches in both.
• Run the repack.bat to repack the data.ayg file, this will create a new file repacked_data.ayg.

How do I create data.ayg from scratch?

• You need two directories extracted and edited_extracted.
• There are two options build.bat which will create packed.ayg and build_minimal.bat which will create minimal_packed.ayg.
• The build.bat script will take all files that are in extracted, and edited_extracted and build packed.ayg out of the files. The files in edited_extracted will take priority / will override anything from the extracted directory.
• The build_minimal.bat will create minimal_packed.ayg which will consist only of the files in edited_extracted, allowing for a much smaller archive.
