How to install mod:
1. Unpack these 3 files:
- boot.config
- RuntimeInitializeOnLoads.json
- ScriptingAssemblies.json
2. Copy and put them to "SiNiSistar2_Data" folder.
3. Say "Yes" to replace existing files.
4. That's everything! Now you can play your game.
Note 1: It is highly recommended to create game shortcut and add these 4 commands to it:
-single-instance -nolog -no-stereo-rendering -force-d3d11
Note 2: To ensure that every game you play honors the settings in the "boot.config" file, set it to "Read only":
Right-click "boot.config" --> Properties --> choose "Read only" --> click Apply --> and then OK.
Ending Notes:
- Mod is compatibile with any version of SiNiSistar2, but you have to change manually Key called "build-guid=" in "boot.config" file which corresponds to the game version that comes up with every new update. Build GUID is "Globally Unique Identifier", and game uses this to track its assets, so you should always use newest Build GUID if "boot.config" file has it there. After extracting new version of the game, just copy-paste new GUID to mod's "boot.config".
- To change renderer that game uses, you have to manually add command of that renderer to game shortcut.
- You can use Unity Arguments in every unity game that has "boot.config" file.
- You can use Unity Commands in every unity game by adding them to game shortcut.
