- Implemented DVDReadVrAsset function to read mapped disc paths for VR assets. - Created HeldItem structure and ReadHeldItem function for managing held items in the game. - Developed unit tests for ReadHeldItem to ensure correct functionality and edge case handling. - Added cockpit item data tests to validate model indexing and parsing of archives.
