  • Implements method and static function handling in createSkyrimPlatform() in wip_sp3.js.
  • Updates SP3GetFunctionImplementation() in ScampServer.cpp to handle static and method calls.
• TSConverter Cleanup:
  • Removes unused Mode enum and related functions in TSConverter.cpp.
  • Simplifies TypeScript output generation by removing interface mode handling.
