  • Name: Unity Plugin for JoiPlay
  • Source: Official JoiPlay Patreon / GitHub repository
  • Purpose: Enables JoiPlay to interpret and execute Unity builds (typically Windows x86 builds) on Android.

Error #5: IL2CPP conversion error

Cause: The game is built with IL2CPP and Mono stripped out. Fix: This is often fatal. However, try downloading the "Mono Unity Player" plugin (a separate experimental build) and select "Mono" instead of "IL2CPP" in the game's plugin settings.
