Proto:Jak II/E3 Demo Disc

This is a sub-page of Proto:Jak II.

To do: This demo has a huge amount of content that is only accessible when it is booted in retail mode, need to document everything. Document music differences.

A demo disc of Jak II that was distributed at E3 2003, but is not the same demo that was playable at the event. Two missions are playable: "Protect Sig at the pumping station" and "Destroy eggs in strip mine". It is dated March 15, 2003 while the final game is dated August 25, 2003.

General Differences

• The title screen has the subheading "demo" and gives the option of playing the two missions or watching a trailer.

Prototype	Final

• The font used throughout the game is the same one used in Jak and Daxter: The Precursor Legacy.
• The native resolution is 512x224 interlaced, the same as The Precursor Legacy while the final game renders at 512x208 interlaced or 512x416 progressive.
• Cutscenes have no subtitles.
• The levels have no Precursor Orbs.
• Dark eco droplets are still sucked in when Jak is fully charged.
• A number of objects have invisible walls surrounding them.
• Some flat surfaces behave as if they were slippery.
• The pause menu makes different sounds. It consists solely of the options "Quit Game" and "Back".

Prototype	Final

• In both levels the skyline is different and resembles the sky used in The Precursor Legacy.

Prototype	Final

HUD

• The Skull Gem icon is a picture of a Metal Head instead of an animated model of a gem. The total number of gems collected is shown in a box to the side.

• Jak's head doesn't appear on the dark eco meter, it instead shows the symbol for dark eco. The symbol is in the final game, but normally hidden behind the head.
• Jak's maximum health is four instead of eight.

Prototype	Final

Pumping Station

• Jak can be controlled during certain cutscenes.
• The game ends as soon as the final cutscene finishes.
• The mountain area does not appear in the background.

Prototype	Final

• The water has a different texture.

Prototype	Final

• Sig's Peace Maker leaves a blue trail behind shots.

Prototype	Final

• The water's defense robot fires different blaster shots.

Prototype	Final

• The airlock produces a spraying effect which was removed from the final game. The lamps are also a different color.

Prototype	Final

Strip Mine

• Jak gets on the JET-Board automatically at the beginning of the level and gets off it when the grinding instructions appear.
• Grinding and tricks do not function well on the JET-Board.
• Certain elements that are only present in earlier missions of the final game are still present in this mission of the demo:
  • Enemies appear that normally only appear in the first mission.
  • The eco wells are shown to still be active.
  • The giant crate next to the building where Vin was trapped is still present.
• A giant, floating arrow points in the direction to go. This may be a prototype version of the light beam used frequently in the final game.

• Metal Jackets shoot a visually different blast.

Prototype	Final

• The Haven City landscape has a number of differences: the weapons factory and surrounding pumping station area is missing, some texturing and coloring of the landscape is different and the palace and stadium do not light up at night.

Prototype	Final

Dark Jak

The appearance of Dark Jak is the same as in the final game, but the powers and moves have some differences.

Movement

The dive attack leaves a red-ish cloud on impact, which slowly fades away, similar to the Scatter Gun's cloud from the same prototype.

Powers

While in the final game the Dark Powers are activated with the buttons used for regular physical attacks and movement, in this prototype they are activated with the D-Pad. A HUD on the top-right is used to display what each of the four D-Pad buttons' functions are, although the icons used for the powers are vague in what they are supposed to represent. There are also four inventory flags in the game's memory used for unlocking Dark Powers, all of which also make the HUD appear. However, only one of these inventory flags actually unlocks a power (Dark Bomb, activated with the Up button), making its icon brighter.

Dark Bomb

The Dark Bomb itself does not have any noticeable differences from its final game counterpart, apart from that it makes Jak collect pickups that are touched by the bomb's impact, and that Daxter is in a T-pose during the animation.

Guns

Scatter Gun

The Scatter Gun produces scattering, red clouds and also has the laser for aiming. It is otherwise identical to the final game.

Prototype	Final

Power Blaster

The Blaster shots are visually different and make a different sound effect, but function the same as the final game.

Prototype	Final

It is referred to as 'Power Blaster' in this prototype:

Vulcan Fury

The Vulcan Fury gun can be used through hacking. It has minor visual and audio differences and also has an issue where it often points at a downward angle, which was fixed in the final game. It also appears to fire more slowly in the demo.

Prototype	Final

Boom Stick

A weapon called the Boom Stick, which would later be replaced with the Peace Maker in the final game, can be used through hacking. It fires small grenade-like objects with a trail resembling dark eco. The projectiles create a large explosion that can send enemies flying and also has the ability to hurt Jak. It is difficult to aim properly and the projectile often bounces off surfaces. It does not create any sounds when used, suggesting it was at an early stage of development.

Concept art of the weapon can be viewed in the "Mega Scrap Book" in the final game:

Unused Menus

There are several unused menus in this prototype that can be accessed using hacks.

Category	Menu Images	Description
Glitched pause menu		These are leftovers from the Jak and Daxter: The Precursor Legacy pause menu. The menu on the second image appears twice in this prototype.
Mission selector		A working mission selector menu. Only a few missions work because many level files are not present in the demo.
Game settings		Several menus used for changing settings of the game. All of these are from Jak and Daxter: The Precursor Legacy and are fully functional.
Memory card access warnings		All of these freeze the game, preventing it from loading any other menus or from continuing the game. They don't do anything with the memory card.
Main menu		The main menu from Jak and Daxter: The Precursor Legacy.
Load/save game menus		The save game menu with the 'continue without saving' option is accessed from the title screen, the other one is accessed during gameplay. None of these work because they can't find the memory card. However, selecting the 'continue without saving' option will start the 'Find pumping station valve' mission.
Other		Several warnings and other menus that do not need explanation. All of them are from Jak and Daxter: The Precursor Legacy.

Unused Graphics

An unknown screen.

WOMDRAWN.STR and WOMEMPTY.STR

To do: See if there are palettes hidden somewhere else in the game.

WOMDRAWN.STR is a 2048 x 3840 pixel image of the world map from The Precursor Legacy with a number of other drawings added to it. The image is stored as 128 x 128 pixel blocks, has a total of 128 colors and does not have a known palette. The image on the right uses a mock-up palette based on scans of the original map which came with the Precursor Legacy instruction manual.

WOMEMPTY.STR is the same image but with all pictures except the background removed. It is also stored as 128 x 128 pixel blocks but unlike WOMDRAWN, it has a total of 256 colors. Likewise, this image doesn't have a known palette with the image on the right using a mock-up palette instead.

Unused Sound Effects

Sound File	Line
	Audio leftover from the Power Cell collection cutscenes in The Precursor Legacy.

Unused Dialogue

The following dialogue is unused in the demo with the files completely removed from the final game.

Like in the Precursor Legacy demo, much of the dialogue with distortions, such as through communicators, is unedited, while a large amount of cutscene audio doesn't yet have the background sound effects.

Cutscenes

	Don't step into the light, Jak. Don't step into the light!	Leftover dialogue from The Precursor Legacy.
	While you're down there, um, could you rub my feet?
	Don't worry, I'll avenge you. Not.
	Heimlich, uh, stretcher?! Yugh, breath mint?
	I'll say something really teary at the funeral, like "How am I gonna get changed back now?!"
	Say goodnight, Jak.
	Well, uh, better you than me.
	Step one: stay alive. Step two: think about not doing something like that again!
	Hey Jak, can I, uh, have your insect collection?
	That looks like it hurt. Should I call for backup?
	I was right behind ya, Jak! Really, I was.
	We gotta get to the top.
	We made it!
	That's what I call a rocky road.
	You sure seem angry, Jak.
	Most of the people aren't very nice. And that nasty Baron who runs things? He's really bad news.
	I dunno where that crazy rift vehicle took us but it's some kinda big city.
	I never found hide nor hair of Keira or Samos. I don't know where they went.
	Good job, see? You still got it.
	Lookin' good, partner. Nice spin kick. Works out some of that anger, eh?
	It's a tough place, Jak. You do remember how to fight, right? Try breaking that crate with a kick.
	Go help Sig!
	Woah. Countdowns are bad news! Let's get outta here!
	Rock and roll.
	The whole city is under martial law and run by some brutish baron guy. You'll need security passes to go from place to place in this town. We'll have to get some of those.
	Sweet move, buddy. Like butter.
	You can punch, right?
	Shoot 'em! Shoot 'em!
	I've seen some weapons around town. Maybe we can get our hands on some of them to deal with even tougher enemies.
	Wow, you really learned to fight in the joint. Remind me not to get you pissed.

Jinx and Grim

	Jinx: Ahh! I'm in trouble!
	Grim: I doubt blue boy here can protect us. Jinx: Just shoot everything that moves and we'll be laughin' about this later over a cold one.

Krimzon Guards

	You're under arrest!
	Wait!
	Stop!
	Say goodnight!

Sig

Sound File	Line
	When I get to each of the targets, cover me while the old Peace Maker powers up, okay?
	Sweep with this weapon for maximum damage.
	You'll need lots of ammo to keep this puppy barkin'.
	The Vulcan gun is one nasty weapon. Its extreme rate of fire will clear a path through almost anything.
	Take 'em all out!
	Good.
	Okay, good shooting.
	Watch me light that tanker.
	Easy does it.

Unknown

Dialogue belonging to unknown characters.

	I think we've overstayed our welcome.
	I'm goin' in!

Unused Text

The file 0COMMON.TXT has unused text that differs from the file of the same name in the final game. All text in this version is in capital letters like in The Precursor Legacy, while in the final game capital and lower case letters are used more appropriately.

Much of the text refers to the game as "Jak and Daxter" instead of "Jak II", including the text used when the disc is removed.

A JAK AND DAXTER SAVE GAME ALREADY EXISTS IN THE SAVE FILE YOU HAVE SELECTED
JAK AND DAXTER
JAK AND DAXTER REQUIRES ~DKB OF FREE SPACE

PLEASE CHECK THE JAK AND DAXTER DISC AND TRY AGAIN
PLEASE INSERT A MEMORY CARD (PS2) IN MEMORY CARD SLOT ~D THAT CONTAINS JAK AND DAXTER GAME DATA
WOULD YOU LIKE TO CREATE A JAK AND DAXTER SAVE FILE?

Other text, including where the Blaster gun is called the "Power Blaster" as seen in the same concept art featuring the Boom Stick. (NB: The symbols for buttons are represented by long strings of text and have been changed to [button] here for convenience.)
