Notes

The Cutting Room Floor research
This prototype has a research article on TCRF.
  • Code and small data changes.
  • The debug menu can be accessed with the same cheat code as the final game (press Right, 1, 2, 1, 2, Down, 2, Up on the sonar map screen).
  • Because the original EPROMs lack a written date, this prototype is classified by the "EPROM" number specified on the debug menu.
