Super Mario Galaxy 2/Unused Mechanics

This is a sub-page of Super Mario Galaxy 2.

Unused Object Types

There are two unused object types in Super Mario Galaxy 2. They are completely unfunctional, but their files still remain inside map archives. While there are many DebugMovePos objects placed around zones, ChangeObj goes completely unused. Debug, which also appears in Super Mario Galaxy, was most likely used by the developers to access various points in a galaxy through a debug menu or something else.

Type	File	Objects
Debug	DebugObjInfo	DebugMovePos
ChangeObj	ChangeObjInfo	ChangeObj

Unused Power Star Spawning Methods

The way how power stars spawn is defined in a field called AppearPowerStarObj inside a galaxy's scenario file. There are a few methods that aren't used in the game at all, most of which are leftovers from the first Super Mario Galaxy.

AppearPowerStarObj	Object	Description
テレサチーフ	TeresaChief	Boo with Power Star (Deep Dark Galaxy)
花さか監視[パワースター]	CountFlowerPowerStar	Flower Counter for Power Stars
音符の妖精	NoteFairy	Rainbow Notes

壊れる籠	BreakableCage	Small Destroyable Glass Cage
壊れる籠[大]	BreakableCageL	Large Destroyable Glass Cage
壊れる籠[回転タイプ]	BreakableCageRotate	Rotating Destroyable Glass Cage

Unused Object Functions

ProductMapObjDataTable is used to create simple objects like rotating platforms or seesaws, where ClassName defines how an object works. Some of these classes are unused in the final game.

ClassName	Description
PriorDrawAir
EffectObj10x10x10SyncClipping
EffectObj50x50x10SyncClipping

Unused Flags

The sixth entry in the flag table "アイスマリオ初変身" is set when the player collects the Ice Flower for the first time. Since the Ice Flower has been removed from the game, the flag is never set. The flags for the Red Star have been removed.

Horror Powerup State

Please elaborate. Having more detail is always a good thing.

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: there is timer related code, probably more

To do: add the original japanese text

This power-up state, internally named Horror, is found between "Yoshi" and Cloud".

If the game determines the galaxy is set to the unused "Horror" comet mode, it tries to load a model referenced by the ID 6, but nothing is ever loaded into model slot 6, so the game crashes. But if you load the Bone Mario model (used in the final SMG1 and SMG2 when Mario is electrocuted), the animations it calls fit reasonably well:

• 

  BoneBreakEnd.bck

• 

  BoneBreakStart.bck

• 

  BoneBreakWait.bck

Once this state is active, Mario will receive no damage from any outside sources at the cost of an extended stun period after taking damage in the form of his skeleton breaking apart. After a short while, he'll reform. Mashing A while broken apart will speed up this process.

When exposed to an object that emits light, such as GlaringLightArea, Mario's model will switch back to his default one, though the power-up state remains the same. Leaving the area will switch his model back.

Some of the unused NPC/Signboard text seems to relate to the Horror comet, providing some clues as to how it would have worked:

KinokoTowerHorrorZone

The Bone's Curse will kill you!
If you get coins, you can live
a little longer... Heh, heh, heh!

CMudplanetHorrorZone

If you enter the light, you can
return to the original form!
Your full health will be restored!

In the final game, there is a similar mechanic in the Speedy Comet missions where the player has to collect timers to prevent Mario dying due to the time running out.

The "とことん楽しむ スーパーマリオギャラクシー2の本" ("Tokoton tanoshimu Super Mario Galaxy 2 no hon") strategy guide contains an interview with the producer, Yoshiaki Koizumi. It it, he mentions a power-up called Bone Mario:

ちなみに、変身の候補には“ホネマリオ“なんていうものもありました。詳しく言えないので、どんな性能だったかな、皆さんのご想像にお任せします(笑)。	By the way, there had been a candidate for a power-up called "Bone Mario". I can't go into detail, so I'll leave it to everyone's imaginations as to how it worked (laughs).
