AreaObj Limitations

The content described on this page is 100% documented.

In both Super Mario Galaxy games there is an internal table that sets up the AreaObj managers. For every manager, there is a limit of AreaObj instances that can be placed in a level. If the game exceeds this limit, the game will very likely crash.

Lists

Below are tables for every game that list the managers with their respective limits.
