Yellow Coin

Revision as of 13:37, 9 September 2018 by MMMMMMMMMMMMM (talk | contribs) (coin spawner, typo)

A yellow coin is an object found in most levels. When Mario interacts with a yellow coin, the coin counter increases, Mario is healed, and the coin unloads. When the coin counter reaches 100 while in one of the 15 courses, a 100 Coin Star is spawned above Mario. The amount that the coin counter increases and the amount that Mario is healed is determined by the coin's value, which is 1, 2, or 5 for yellow, red, and blue coins, respectively. Some yellow coins are spawned by Coin Spawners.

Various glitches such as cloning and Time Stop can be used to spawn and collect more coins than there are intended to be in a level.

Coin Duplication

When Mario interacts with a coin, a flag is set which informs the coin to unload when it next updates. When the coin unloads, it marks itself as "collected" so that it does not spawn again when Mario leaves the area and returns. Using cloning or Time Stop, we can prevent the coin from updating, and thus collect it without the coin being marked as "collected". This allows us to spawn the coin again, even after collecting it, effectively duplicating the coin.

In this way it is possible to collect more than the normal number of coins in a level. In several levels, it is possible to increase the coin counter to 999. However, when using cloning by itself, each duplicated coin takes up an object slot in memory. There are only 240 object slots total, and attempting to spawn an additional object once all of them are full will cause the game to freeze.

Collecting more than 255 coins in a level will not increase your in-game high score, however. Due to how the game keeps track of the score, it actually saves mod 256 for the total collected coins.
