Jak Speedrunning Practice (OpenGOAL)

Jak 1

Button combination	Effect
Hold L1+R1+X and press Start or Select	Brings up speedrunner menu for fast resets and access to custom checkpoints.
Hold L2 and press dpad Down (or CTRL + C)	Set a custom checkpoint at Jak's current position (also remembers if you are on flutflut or zoomer). Only works if Jak is in an "idle" state. Plays a sound to confirm.
Hold L2 and press dpad Up (or CTRL + V)	Reset to last selected skip/trick, or to custom checkpoint, whichever was used most recently. If you also hold R2, for custom checkpoints it will reset the entire game.
Hold L2 and press dpad Left	Get on flutflut, or get off flutflut/zoomer if already on.
Hold L2 and press dpad Right	Get on zoomer, or get off flutflut/zoomer if already on.

• If inputs are not working, double check that Speedrunner Mode is enabled under Misc Options
• Known Issues:
  • if you set a custom checkpoint while Jak is swimming, on respawn the camera likes to go crazy and zoom out until the level deloads
  • Respawning during a cutscene can sometimes crash when the cutscene finishes
  • Custom checkpoints don't perfectly restore the camera zoom
