Safety Notice
Use Mods Carefully Around Anti-Cheat
Avoid online or anti-cheat protected games. Modified DLLs, injectors, overlays, or replacement libraries can be treated as suspicious by anti-cheat systems even when the user's goal is visual customization.
Keep backups, test offline, verify file locations, and remove added files if a game becomes unstable. Do not assume every manager, client, mirror, or download page is part of the original project.
