Module File Split

  • _ModuleEntryPoint/sub_594 are entry paths in PlatformErrorHandler.c.
  • PlatformErrorHandlerConstructors, RegisterPlatformErrorHandler, PlatformErrorHandlerFallbackInit,
    RegisterErrorNotificationCallback, RegisterErrorSource, DispatchNotification,
    and DispatchWithEarlyOut are in this module directory and are exposed for cross-file linking.
  • Helpers for MC-bank access (sub_1D8C / sub_1DE4 / sub_1E3C) are still documented in emcaplatformhookslib.c.
