NOTE

• Please do not use this mod with some overlays like FPS Counter in Nvidia GeForce Experience, MSI Afterburner, RivaTuner Statistics Server, etc. They may cause the game to crash.
• You can use EROverlay.dll to load multiple overlays, I will keep the back compatibility so that you just need to make sure Overlay Loader version meets the minimal requirements for certain overlay.

USAGE

• Modify .ini's inside configs folder to your liking.
• Inject the mod to Elden Ring, you can either:
  • Rename EROverlay.dll to winhttp.dll and put it aside eldenring.exe (don't forget folders configs and data).
  • Load EROverlay.dll with any mod loader (EldenModLoader, ModEngine2 or me3).
  • Run injector.exe to inject (not recommended, because that this method is not very stable and is blocked by some security softwares).
• Wait few seconds until the mod is fully loaded, press = to toggle mini/full mode.

WRITE AN OVERLAY PLUGIN

• Read code comments in src/api.h for details.
• Read codes in src/bosses/dllmain.cpp as an example.
