JumpStart 3D Virtual World / World of Jumpstart

Trying to preserve/recover the old World of JumpStart Marineland (Windows 1.1.0) files and I’m missing several Unity asset bundles that appear to have originally been downloaded dynamically from JumpStart servers.

I specifically need the ORIGINAL matching versions of:

  • MarineLandIntro.unity3d
  • NPCsML.unity3d
  • NPCGenDialogML.unity3d

Important: they need to be from the World of JumpStart / Marineland WIN 1.1.0 build (not older Lost Island Quest builds), otherwise Unity throws “asset bundle not compatible with this version of the Unity runtime.”

I already have:

  • MarinelandRes.unity3d
  • JSMarineland.xml
  • the game executable/runtime working offline

The game now boots to the Marineland loading screen, but hangs because the actual scene/NPC bundles are missing.

If anyone has:

  • an old installation
  • archived JumpStartUnity/Marineland/WIN/1.1.0 files
  • preserved asset bundles
  • or knows where these were cached/downloaded

please let me know. Even filenames, folder structures, or partial archives would help massively with preservation/reverse-engineering efforts.
