Arguments
Description
Using a method similar to the texture loading decision process, this macro evaluates the status (status ID) and then branches to another display list according to the True/False result. The macro uses the following processes to decide whether or not to branch to the other display list:
The status region is set using gSPSetStatus (see the "4.7.1 gSPSetStatus" in the Readme of the latest version of the S2DEX microcode).
This macro differs from gSPSelectDL in that the display list to be used is not pushed on the calling stack. In other words, this macro's call is a "jump" and not a "call" like the gSPSelectDL macro. Both macros are used to link long lists.
Note
Unlike gSPSelectDL, there is no return to the calling display list even when the target display list after the branch is completed.
