An '''idle deload''' is a bug in the game's level loading system that can be used to load in fail-safe/stored checkpoints and levels. If performed correctly you will generally see your current level deload to a black void and as the pause menu opens your location should change to the next checkpoint the game has available.
'''Low eco''' is a speedrun category in [[Jak and Daxter: The Precursor Legacy]] that restricts the player to using the lowest possible amount of eco needed to completed the game.  


Idle deloading is used for Klaww Skip, Lava Tube Skip, and for Citadel Skip only in All Orbs and All Flies categories.
[[Lava Tube Skip]] is banned in Low Eco. If it wasn't, Low Eco would be a slower and more boring version of [[Any%]]. The point of the category is to see how the runners manage to complete various tasks without the use of eco.

On a technical level, an idle deload is when the game's backup load state sequence is interrupted and only the restore function is executed.
''Currently, the only eco required to beat the game are the 8 on final boss (3 blue for launchers and 5 yellow. Green eco on the second phase must be avoided).''


During cutscenes, certain objects or characters need to be moved around or deloaded as the cutscene plays out. After the cutscene is over, the game needs to be able to return all the characters and objects to their original positions before the cutscene was started. In order to do this, the game creates a backup load state right before the cutscene begins. It then refers to the data within the backup load state after the cutscene is finished to properly return everything to how it was before the cutscene started. This backup load state process is controlled by the game's animation system, which is also used by 3 other events: Jak dying, Jak using the warp gate, and Jak performing an idle animation after 30 seconds of standing still. This means that these 3 other events can trigger the backup load state sequence.
''If eco is accidentally collected, you may load a save file to a previous state in the game, or immediately die to return to a previous checkpoint. Otherwise, you must reset.''

The idle deload was discovered by headstrong1290 on accident in [https://youtu.be/59dhHVL8Frs?si=6-EoxVJmVO18-Gky&t=1219 February 2016]. Blahpy figured out how to reproduce it a few days later. On August 22, 2021, Snugggles would discover the "button holding" method of the idle deload, which is the most commonly used method today.  
 
Idle deload's first useful application for speedrunning was discovered by Boomer and yankee027 while accidentally doing Klaww Skip.
