General Differences

  • The opening FMV now has its music start at the Traveller's Tales logo, and its palette now changes when called for, but the screen height is still 160 pixels, is a bit faster than in 94, and has one extra frame before the title screen.
  • The music doesn't stop if the opening is skipped.
  • The title screen matches the final, but lacks the trademark.
  • No sound effect plays when the title screen pops up.
  • All demos have been implemented.
  • Level select is disabled by default; The final code has been implemented.
  • The good ending still plays the credits music throughout, but its entirety has now been implemented.
