Hmmm...
To do:
Need more descriptions for things (still) and Possibly re-organize this page
This page details one or more prototype versions of Metroid Prime.

In 2002, Nintendo released Version 7, 8 and 9 of their in-store kiosk disk, which included a Metroid Prime demo.

Differences

Title Screen

Proto Final
MPDemoTitleScreen.png Metroid-Prime-Titlescreen.png

Most notably, the title screen is much darker (due to the "scanlines") and the logo in the center is different from the final version. There is no file select screen because this is a demo. However, videos of the transitions from main menu to file select screen, etc. to etc. exist in the final game's files.

Save Function

The prototype lacks a save function; all Save Stations are disabled.

Pause Menu

Proto Final
MPDemoMap.png Metroid-Prime-Pause-Menu-Final.png

The pause menu consists only of a simple map viewer in place of the Inventory Screen. The "Opened doors" are blue instead of green and the "Closed/All Beams" Doors are white instead of blue. Also the player location "peg" is white and triangular instead of green and roundish.

World Map

Proto Final
MPDemoWorldMap.png MPWorldMap.png

The world map in the demo is unfinished and contains remnants of an older world layout for the game. At this time, the world map only contains Tallon Overworld (middle), Chozo Ruins (bottom), Phendrana Drifts (right), and Phazon Mines (top). According to internal room names, Magmoor Caverns was once part of Tallon Overworld. It is unknown if the Crashed Frigate was implemented yet.


HUD

Proto Final
MPDemoHud.png Metroid-Prime-Hud-Final.png

In the final, the HUD is much brighter, enhancing the 3D effect. The energy bar was changed, with energy tanks and the word "Energy" being moved from the left to the top of the HUD. The beam icons lack their respective colors and have a turquoise color instead. The edges of Samus' helmet are also different, being more curved than in the prototype. Blue lights were added to the bottom, and the frame was brightened.

Opening Credits

Proto Final
MPIntrotext.png Metroid-Prime-Intro-Text-Final.png

In the prototype, the message in the opening reads "Orbit inclination 51.60" 226 kilometers above the planet tallon IV." and has a different, blue-coloured font, while in the final version it reads "Unidentified distress beacon has been tracked to a derelict space vessel in orbit above Tallon IV" in a white font different from the one in the prototype.

Weapons and Visors

Hmmm...
To do:
Add images of the final game's beams and visors for comparasion.
Beams

All beams in the prototype vary somewhat from the final version.

Ice Beam

Mp demo ice beam.PNG

  • The Ice Beam takes longer to start charging. It takes approximately 2 more seconds to start.
  • Samus starts in the Frigate equipped with the Ice Beam; she does not have this beam here in the final. Additionally, its position is on the right (where the Wave Beam would be in the final).

Plasma Beam

Mp demo plasma beam.PNG

  • Has a different texture than the final. Its texture is more like fire than magma.
  • The Plasma Beam's charged shot is a slow ball of fire, unlike the final's large "beam".
    • The slow ball of fire follows the nearest enemy without having to lock onto that enemy.
    • The charging animation for the Plasma Beam is incomplete.
  • The Plasma Beam is missing many of its sound effects and has a different firing animation for its charge shot.
  • An uncharged Plasma Beam shot lasts much longer than the final version, giving it a much slower rate of fire.
  • It also seems to prolong the animation of whatever it hits; this is most noticeable when used on Parasites.
  • Collision detection involving it seems off; it has a tendency to "miss" completely and it sometimes fails to burn enemies.
  • It seems to have multiple hitboxes and ignores shields (the latter seems to be intentional)

Wave Beam

Mp demo wave beam.PNG

  • The Wave Beam seems to be unable to damage Auto Defense Turrets, instead of disabling them immediately.
    • Does a lot more damage when compared to the final; two uncharged shots can quickly dispatch a Space Pirate.
  • The charging animation for the Wave Beam is incomplete.
  • The Wave takes longer to start charging. It takes approximately 2 more seconds to start.
  • The Wave Beam functions slightly differently from the final version; uncharged shot fire 4 shots in a plus pattern rather than the final's 3. A screenshot on the demo disc shows that this was a later change.

Other Weapons

  • Missiles work slightly differently from the final version: the Y button activates missiles. Pressing Y again in "missile mode" fires a missile. This behaviour was removed in the final.
  • Power Bombs can only be used whilst the player is completely still. Upon use, the player cannot move until the animation ends (playing the "Game Over" sound at the peak of the explosion).
    • Presumably, this would have been used to test the death animation in Morph Ball mode.
  • Bombs have a different explosion effect from the final, resembling a lingering blue orb.
  • Charge Combos are present and work as they do in the final version, though they have a different (and much longer) start-up animation.
    • Missile costs are lower than in the final; all Charge Combos use 5 missiles to fire as opposed to 10 (5 for the Super Missile) in the final.
    • You start with all beam combos by default, even though you don't start with the beam that has that combo.
    • All charge combos besides Plasma Beams's aren't any different.
  • The Flamethrower is somewhat buggy and does not work as intended.

Scan Visor

Mp demo scan visor.PNG

  • Scanning takes a fair amount longer than in the final.
  • All Scan Points use the orange icon, whereas the final has both orange and red points.
  • The game does not pause upon completing a scan.
  • The dialogue box that displays text is mostly silent in the final.
  • The Logbook presumably is disabled for the demo; no scans are recorded to it.
  • The scan text seems to be different.

Thermal Visor

Mp demo thermal visor.PNG

  • The Thermal Visor uses a different palette from the final, consisting of colours ranging from red to blue. Additionally, its sound effect is different.
    • Additionally, there is a static effect over the screen and most of the visual elements are missing, except for visors and beams.
    • The Thermal Visor's beeping noise that it plays when equipped seems to be different.

X-Ray Visor

Mp demo x-ray visor.PNG

  • The X-Ray visor has an old, runic/ancient circular look.
  • The X-Ray visor targeting reticle is always visible. Also, the roundish dashes around the reticle move left or right around the reticle depending on which way you turn the visor.
  • The X-Ray visor's HUD is circular, with the warning indicator and missile count around the circular HUD.
  • The X-Ray Visors palette doesn't seem to make things transparent, such as the arm cannon.

Early Title Screen

Present in the videos directory is an unused movie of what appears to be a very old main menu screen loop:

A variation of this early logo (without the subtitle) appears in image 6 and 7 of the Metroid Prime gallery on the "Nintendo GameCube Blockbuster Preview Disc 2002" DVD.

Included Rooms

No other worlds (like Phendrena drifts and Tallon IV) are present on the disc. No "extra" rooms are included in the Space Pirate Frigate.

Inaccessible Equipment

While inaccessible in normal gameplay, most of the final's equipment is present, coded, functional, and can be activated using Action Replay codes:

Action Replay code Equipment Notes
00372C4B 00000001 Wave Beam Fires four shots instead of three.
00372C53 00000001 Plasma Beam Uses different textures to the final version. Animations and sounds seem unfinished.
00372C6F 00000001 Power Bomb
00372C83 00000001 Thermal Visor Uses a different palette and SFX from the final version.
00372CA3 00000001 X-Ray Visor Does not work correctly. When switching to it, the game appears to be unable to read data related to the Visor and crashes.
However, by changing another value in the same area of memory (0x00372C1F), one can make the game switch off a Visor,
including the X-Ray Visor (0x01), which gives approximately one second of correct x-ray vision before it switches to the Combat Visor.
00372CAF 00000001 Space Jump Boots
00372CCB 00000001 Boost Ball
02372C54 000003E7
02372C58 000003E7
Always Have 999 Missiles
00B87BC6 00000099 Make X-Ray visor work You must be in emergency evacuation area where the injured space pirate is.

As mentioned above, this area of memory holds several more flags and values that toggle or otherwise change the available equipment, such as the current amount of Energy Tanks.

Hmmm...
To do:
More information about equipment (maybe?), maybe more about this memory area.

Unused Models

MP DEMO Samus hand pads.PNG

An early version of the Varia Suit featured pads on the left hand.


Metroid-Prime-Unused-Collectible.png

An unused pick-up model with an unknown purpose.

Demo Exclusive Models

These models were used in the demo, but not in the final game.


Metroid-Prime-Demo-Morph-Ball.png

A morph ball exclusive to the demo. The color scheme suggests it's meant for the gravity suit, however there is no further evidence to support this theory.


MP DEMO sova.PNG

An enemy named Sova that appeared in the demo but never made it to final.


MP DEMO Wave beam FP.PNG MP DEMO Plasma beam.PNG

Wave and Plasma Beams, respectively.
