Power Stars are collectible items that are required to progress and beat the game (without using glitches to bypass the requirements), as well as to open star doors. The star counter keeps track of how many stars you have collected, and there are 120 in total.

100 Coin Stars

Main article: 100 Coin Star

100 Coin Stars are special Power Stars that spawn in the main courses when Mario collects 100 coins.

Technical information

Height

Every Power Star spawns at a different height from the floor below it. Todo: Migrate this info into a table and place it here. Include Red Coins on the Ship Afloat without the Ship (7519 units).

Position

Most stars spawn with coordinates that are divisible by 100, although 100 Coin Stars can spawn anywhere. Some stars are always loaded, while some (such as Red Coin Stars and Secret Stars) load during the level at a Star Spawner.

Yaw Velocity (Angular Speed)

Power Stars spawned from a ! Block have a yaw velocity of 1024 angle units per frame (168.75 deg/s). All other Power Stars have a yaw velocity of 2048 angle units per frame (337.5 deg/s). Why these values are different is unknown. All Power Stars spin counterclockwise when viewed from above, similarly to a globe.

Storage in memory

Power Stars are stored such that it is impossible to collect more than 120 stars by collecting two of the same star, even if both are yellow.
