8009e690 is the location of the pointer table for the Menu Controller routine, Facts are called with the routines x2E (80092434 - Fact Menu Idle) and x2F (800928ac - Display Fact Name?). It appears pointers x3A - x3C are empty and available for custom functions if needed.

The way the game processes the next menu is that at the end of the routine a value (ranging from x00 to at least x3c) is stored at 800d4580 + Menu "Depth" * 4. The Menu Controller then uses this value to load the offset from the pointer table.

• Menu Depth being how many menu's deep you are until you're out of the menus screen.

Data Locations

800bb4f0 - Menu Depth
800bbc70 - Graphic Display Data
  0x0000 - Graphic Displayed?

800d4580 - Next Menu Routine (This pointer is updated by 4 and is loaded as a word, I've seen many routines use 800d4584 as the base offset to store this data.)
