Warnings and review limits

  • Back up saves and generated interop assemblies. Polyfill changes loader-generated game assemblies and runtime behavior; backup/restore uses copy-overwrite and may fail or be interrupted. Use polyfillrestore, restart and verify restoration before removing both DLLs.
  • Designed for Schedule I 0.4.6/0.4.7 with external MelonLoader 0.7.3 or newer. Both bootstrap and runtime DLLs are required; exact game/loader/mod combinations were not executed or compatibility-tested.
  • A missing post office can be restored with default content and affect the next saved world. Do not claim saves are untouched.
  • Optional opt-in reports send mod names/versions/authors, compatibility results, bounded error method-frame chains, play duration and a persistent random installation ID to the developer's HTTPS endpoint. Sharing defaults off until consent; polyfillshare off disables it and polyfillshare show previews the payload.
  • Static exact artifact review found no material security blocker; no runtime or reproducible-build certification. External loader/game libraries are not certified.

Getting started

Back up saves and loader-generated interop assemblies. Place Polyfill.Boot.dll in the game Plugins folder and Polyfill.dll in Mods; retain both. Use a compatible Schedule I/MelonLoader installation; each multiplayer player relying on the old mod needs Polyfill. To remove: run polyfillrestore, restart and verify generated assemblies restored before deleting both DLLs.
