Notes and Comments
- The games using MPL archives have been created using mTropolis Editor. In the game's final builds mTropolis Player (MTPLAY32.EXE) is used to read data from MPL archive.
- In "Muppet Treasure Island" game there is only one MPL archive called MTI1.MPL. It holds most of the game's data.
Compatible Programs
- Muppet Treasure Island MPL Tool (unfinished)
- mTropolis Editor (not available for public)
- mTropolis Player
