Disclaimer: Use this at your own risk. This is literally just a BepinEx plugin I slammed together in 5 minutes because I refuse to pay for content that's already on my hard drive.
Don't pay for skins, kids
- Install BepinEx for your system from BepInBuilds. Follow the installation instructions. Make sure you select IL2CPP, not Mono. Copy the files into your game folder so that there's a folder "BepInEx" next to "AimLab_tb.exe".
- Launch the game at least once.
- Edit "BepInEx/config/BepinEx.cfg" to disable the console window for log output. This is really only for developers and clutters up your desktop. Find the entry "Enabled" under "Logging.Console" and set it to false.
- Open the project, fix the dependency paths if necessary, and build it.
- Copy the resulting binary ("AimlabSkins.dll") into the BepinEx plugins folder (this folder will be created after you first launch the game post-install).
- The game will now blindly assume that you own every skin.
