======== Star Select Rendering ========
The star select screen is rendered using a combination of geo layout functions and behaviors for the stars. Much of the screen uses custom asm to generate the F3D display lists.

The main menu level script (2A6120-2A65B0) contains the level script for the act selector starting at 2A6238. This includes a check on course number (asm 8024BE14), a geo layout for the star select screen (seg 14000408, ROM 2A6528), and a behavior for the spinning stars (seg 13003048, ROM 21CE48).

===== Level Script =====

The level script for the star act selector starts at 0x2A6238.

===== Geo Layout =====

The geo layout for the act selector is defined by the StartArea 0x1F level command above (seg 14000408, ROM 2A6528)

    0x09000064

===== Star Behavior Script =====
The rotating star behavior contains two ASM routines 80176B20 and 80176DF0 which generate the act selection stars and rotate the selected star.

<code>
00 08 00 00
11 01 00 01
0C 00 00 00 80176B20 // ROM: 0x226FE0, Creates menu stars
08 00 00 00
   0C 00 00 00 80176DF0 // ROM: 0x2272B0, Rotate stars/select act
09 00 00 00
