Notes

ovl_file_choose manages the Language Select (PAL only), File Select, File Name, and Options Menu screens.

All Zelda 64 titles including Ocarina, Master Quest, and Majora's Mask use almost the exact same ovl_file_choose. All textures used by ovl_file_choose are pulled from title_static which is loaded at the same time.

Hacking Notes

The loops for the Options Menu Titles and Options Menu Options are very similar. With a little extra code, the two can be combined freeing up a lot of space for your own code. This applies to all Zelda 64 titles.

Four lines, one for each corner of the texture. The x- and y-coordinates are from the center of the screen, so low numbers are up/left and high number are down/right.
