Set six months after the events of Back to the Future Part III, Marty must now rescue Doc from the past and make sure that everything he knows still exists! This is as close to a proper Back to the Future Part IV as we're ever going to get.

(Note: The content of this page (currently) only applies to the PC and Wii versions of the game.)

To do:
There's lots of unused lines and voice samples left in the game. Also tons more Sam & Max leftovers! should cover the 30th Anniversary Edition as well.

Debug Menu

All five episodes have a debug menu that can usually only be opened in development builds. Once re-enabled, it allows the player to teleport to all rooms, with the option of disabling entry cutscenes.

Unused Audio


Leftover sound from Sam & Max Save the World.


Found with the episode select screen exclusive to the Wii version is this unused boing sound.

Unused Gamepad Button Icons

Icons for a generic gamepad, an Xbox 360 controller, a PlayStation 3 DualShock 3 pad, and a Microsoft Intellimouse are present in all five episodes. While all support gamepad input, none of them use these icons. Episodes 2 through 5 use a different set of graphics for the Xbox 360 pads that includes icons for the bumper buttons and both sticks.

Leftover Music

The files "mus_cs_env_bankvr_giveboscoabillion_e1_1", and "mus_cs_env_officevr_use_rathole_e1_1" are both leftovers from Episode 5 of Sam & Max Save the World.

PC Version Leftovers

Throughout the lua files of the Wii version (maybe in the other versions, and maybe other TellTale games) is the following comment about a missing end to a string:

    -- WARNING: missing end command somewhere! Added here

'setup.lua' contains Leftovers from the PC version's options menu, such as the windowed, fullscreen options, render quality, and a "Project Registry Key" presumably also from the PC version. The Wii version does not contain any video settings.

local kRenderQuality = "Render Quality"
local kScreenSize = "Fullscreen Size"
local kWindowed = "Windowed"
  local regKey = prefs["Project Registry Key"]
  if not RegistryKeyExists(regKey) then

'directcontrol.lua' contains more options menu leftovers, shown below.

local kWindowSize = "Window Size"
 -- WARNING: F->nextEndif is not empty. Unhandled nextEndif->addr = 11 


A dummy action is mentioned within the 'navigate.lua' file, and also some nil which is mentioned throughout the various lua files of the game.


Navigate_SetPlayer = function(player)
  -- upvalues: mPlayer , SetRunning , mScene , mPivot , mPivotParent
  mPlayer = player
  if mPlayer then
    local pivotName = "obj_pivot" .. AgentGetName(mPlayer)
    if IsToolBuild() and not AgentExists(pivotName) then
      local parent = AgentCreate(pivotName .. "Parent", "dummy", nil, nil, mScene, true, false)
      AttachAgent(parent, mPlayer, false)
      local pivot = AgentCreate(pivotName, "dummy", nil, nil, mScene, true, false)
      AttachAgent(pivot, parent, false)
    mPivot = AgentFind(pivotName)
    mPivotParent = AgentGetParent(mPivot)

A 'dummy.prop' file, that's all.

Invalid Hint Text String

To do:
Get the message to show up someway on the PC or Wii port of the game.

In the 'hints.lua' file, there is text that is usually not seen that will say the text could not be found, or is unreadable.

    Print("Dialog node \"" .. nodeName .. "\" doesn't exist or isn't visible; unable to deliver hint")

Mentions Of Other Ports

This string in the utilities.lua file mentions all the other ports of the game.
