A simple DLL injector and anti-cheat disabler for Marvel Rivals made entirely in Python.

Tutorial video coming soon™

Features

• Ability to select a dll for injection and inject it
• Ability to select an injection method
  • For now it only supports LoadLibraryA
• Ability to disable the Anti-Cheat for Marvel Rivals

Important

Every game update a few dll's get added to the game files that can cause GPU crashes for some users when using internal hacks. Search and delete/rename these dll's in your game files.

Also, make sure you have this command in your launch options: cmd /min /C "set __COMPAT_LAYER=RUNASINVOKER && start "" %command%"
