#UmaiUme Launcher

UmaiUme Launcher (or UULauncher for short) is a custom Unity game launcher that allows to patch game's assemblies before running the game.

UULauncher currently supports patching ReiPatcher patches only, but more functionality may be added in the future.

Main Features

• Run instead of the game's executable to patch and launch the game
• Easy to set up
• Automatically restores assemblies to unpatched state when the game exits
• Logs every launch
• Compatible with other patchers (Sybaris, IPA, ReiPatcher, etc.)
• Open-source!

All in all, if you are familiar with Illusion Plugin Architecture or Sybaris, this tool will feel rather familiar.

How to install (basic guide)

1. Install tools for ReiPatcher support

Currently UULauncher requires the following assemblies before working:

• ReiPatcher.exe
• Mono.Cecil.dll
• ExIni.dll

Download these assemblies and place them in the same folder (e.g. <Game Root>\Patches\ReiPatcher). NOTE: You do not need to have ReiPatcher installed.

2. Launch UULauncher.exe

Put UULauncher.exe into the game's root and run it once.

On the first launch, UULauncher will prompt you to create the configuration file. Press Yes to create the configuration file.

For more info, run UULauncher.exe -h which will show a help screen.

3. Edit UULauncher.ini

Edit UULauncher.ini with a text editor of your choice. Follow the instructions in the configuration file and edit all the required fields to your preference.

Some ReiPatcher patchers require to add some addition fields into the configuration file (e.g. UnityInjector). Refer to the guide of the specific patcher for more info.

4. Launch UULauncher.exe

Finally, launch UULauncher once more. If the configuration file was edited correctly, UULauncher will patch the game and run it.

How to use

Just run UULauncher every time you want to launch the patched version of the game.

Running the game's original executable will run the unpatched game.
