Hmmm...
This page is a work in progress.

To do:
  • Give better descriptions to "debug texts".
  • Indicate what works in "limited" debug mode, and what requires full debug mode.

Debug Mode is a feature in the first four Jak and Daxter games that unlocks the ability to activate debug text or abilities by pressing buttons..

Activation

Not all Jak and Daxter builds allow their debug modes to be activated with a button sequence. Also, some of them require you to use the "alternate" sequence. You can find information about the debug mode of specific Jak and Daxter builds in the Game Build Database.

The code has two parts, but you can input it in one go and it will work fine. Inputting the first part will only give you a limited debug mode, while also inputting the second code will fully unlock it. You will hear sounds when you successfully input a code (in case you are inputting the full code, you will hear a sound at the middle and at the end).

On the Vita, use the rear touch pad to replace buttons: Top left - PlayStation button L2.svg, Bottom left - PlayStation button L3.svg, Top right - PlayStation button R2.svg, Bottom right - PlayStation button R3.svg

To fully deactivate debug mode, just enter the first part of the code.

Activation Tips

Try these if you are having problems with activating debug mode:

  • Input the two parts of the code separately.
  • Try inputting the codes in the pause menu or the "Press Start" screen.
  • Do not move PlayStation button analog L.svg while holding down PlayStation button L3.svg.

Known Button Combinations

The button combinations below are confirmed to be working on the following platforms: PlayStation 2, PlayStation 3, PlayStation 4, PlayStation Vita.

There is no known way to use the second controller combinations on the PlayStation Vita.

Jak and Daxter: The Precursor Legacy

First controller:

  • PlayStation button R2.svg: Push Jak, Zoomer or FlutFlut upwards, you can hold it down to ascend endlessly.
  • PlayStation button R2.svg (while or after bumping into something or giving/taking damage): Restores 1 health. You can also restore health if Jak is dying, which means that you can avoid death.
  • PlayStation button L1.svg + PlayStation button R1.svg + PlayStation button L2.svg + PlayStation button R2.svg: Enter free camera mode. Also disables Jak, and doesn't prevent the loading of levels as long as you are not going out of bounds too much.
  • PlayStation button L1.svg + PlayStation button R1.svg + PlayStation button L2.svg + PlayStation button R2.svg (while in free camera mode): Exit free camera mode. Respawns Jak in front of the camera, and also sets a checkpoint which immediately gets overwritten by an in-level checkpoint in most cases.
  • Hold PlayStation Up button.svg and PlayStation Left button.svg then press PlayStation button Select.svg: Restart the game. If you are in free camera mode then it only resets your current game state (clears everything) and doesn't restart the game.
  • PlayStation button L1.svg + PlayStation button R1.svg (while in pause menu on the power cell screen): Awards the selected power cell to the player. While this does increase the power cell counter, it doesn't get removed from the world and collecting it won't increase the counter any further.
  • PlayStation button L3.svg + PlayStation button C.svg (while next to an active warp gate): Unlock all warp gate destinations. You need to press PlayStation button C.svg when you can see the "PRESS PlayStation button C.svg TO USE." message. You can start holding PlayStation button L3.svg before that.
  • PlayStation button L3.svg (while standing on a trans-pad): Spawn the Zoomer or FlutFlut that should be on the trans-pad you are standing on.
  • PlayStation button L3.svg (hold while standing on the Fisherman's boat or the gondola): You will see the "PRESS PlayStation button C.svg TO USE." message as long as the button is held down. Allows you to use them before unlocking them.
  • PlayStation button L3.svg (during autosave): The game will show auto-save/ get-heap 0-3 (depending on location of save file), then auto-save/ save done above the autosave icon
  • PlayStation button L3.svg (hold while paused in the power cell menu): Display death counter: "fcd: X"
  • PlayStation button R2.svg (while game is paused and the PlayStation button Start.svg button is held down): The game advances 1 frame then pauses itself. If PlayStation button Start.svg is not held down, then the game will unpause itself, but only if you can see the text "PAUSE" on the screen.
  • PlayStation button T.svg (during credits): Skip the credits.

Second controller:

  • PlayStation button T.svg: Toggle debug text.
  • PlayStation button R3.svg (hold): Display debug text.

History

Events strongly related to Debug Mode's discovery, in chronological order:

  • Luminar Light has found something that somehow activated full debug mode in Jak and Daxter: The Precursor Legacy. It was related to button inputs. He also told the speedrunners that there might be a way to activate full debug mode in any Jak and Daxter game using button inputs, but they were not interested at that time.
  • A way to activate Debug Mode in any of the Jak and Daxter games and builds with memory editing was found by Luminar Light. He then started working on a trainer to eventually make it accessible for everyone in PCSX2 (a PlayStation 2 emulator).
  • Luminar Light contacted ImJustATester about the discovery he made earlier. Together they figured out which buttons were needed for the Debug Mode activation sequence, and also learned its length.
  • Kuitar and Vaser have figured out the correct order of the buttons and got the Debug Mode activation sequence.

Although the main person behind (re)discovering Debug Mode was Luminar Light, there were several people who have helped him and/or are worth mentioning:

  • DonkeyPlanet, using one of Luminar's methods, has found a way to activate Debug Mode in the Jak and Daxter: The Precursor Legacy (Earlier Demo). This was triggered in a different way than Debug Mode in all later builds we had/have access to, so this discovery did not help too much (because the buttons method did not work in the demo anyway, and the memory editing method was different in this demo). Still, this is worth mentioning, because this is the first known case of someone having access to Debug Mode outside of the Naughty Dog dev team.
  • ImJustATester helped with figuring out which buttons were needed for the Debug Mode activation sequence, and also the length of the sequence.
  • Kuitar and Vaser were the people who put the needed buttons into correct order for the first time.
