Catalyst

Next-generation performance mod for Project Arrhythmia - Successor of Potassium

Made for the development & legacy branch

Does not support the Editor!

Usage

For default branch

As of December 28th, 2022, this mod no longer works on editor-alpha branch due to BepInEx not working properly on it. Unfortunately, there is nothing that can be done on my side and requires BepInEx to fix it on their side.

• Download BepInEx 6 x64 IL2CPP (The file that says BepInEx_UnityIL2CPP_x64_6.0.0-pre.1.zip)
• To open Project Arrhythmia Path, go to Project Arrhythmia in your Steam library, click the Settings icon, go to Local files and click Browse
• Extract the downloaded zip file into <Project Arrhythmia Path> using WinRAR or 7-zip
• Launch Project Arrhythmia
• If you have done everything correctly, there should be a plugins folder in <Project Arrhythmia Path>/BepInEx
• Close Project Arrhythmia
• Drop the AlphaCatalyst DLL and the Catalyst.Engine DLL into the plugins folder
• The mod is now installed, you can now enjoy your boosted framerate

For legacy branch

• Download BepInEx 5 x64 (The file that says BepInEx_x64_5.4.21.0.zip)
• To open Project Arrhythmia Path, go to Project Arrhythmia in your Steam library, click the Settings icon, go to Local files and click Browse
• Extract the downloaded zip file into <Project Arrhythmia Path> using WinRAR or 7-zip
• Launch Project Arrhythmia
• If you have done everything correctly, there should be a plugins folder in <Project Arrhythmia Path>/BepInEx
• Close Project Arrhythmia
• Drop the LegacyCatalyst DLL and the Catalyst.Engine DLL into the plugins folder
• The mod is now installed, you can now enjoy your boosted framerate

For development branch

• Download the core libraries from BepInEx
• Download the Unity libraries also from BepInEx

Those steps are required because the development branch DLLs are stripped so we need the original DLLs to unstrip them (otherwise BepInEx won't load)

• Extract everything inside the core libraries zip file from BepInEx into <Project Arrhythmia Path>/Project Arrhythmia_Data/Managed, choose Replace All
• Extract everything inside the Unity libraries zip file from BepInEx into <Project Arrhythmia Path>/Project Arrhythmia_Data/Managed, also choose Replace All
• Download BepInEx 5 x64
• Extract the downloaded zip file into <Project Arrhythmia Path>
• Launch Project Arrhythmia
• If you have done everything correctly, there should be a plugins folder in <Project Arrhythmia Path>/BepInEx
• Close Project Arrhythmia
• Drop the DevelopmentCatalyst DLL and the Catalyst.Engine DLL into the plugins folder
• The mod is now installed, you can now enjoy your boosted framerate
