−	'''ovl_file_choose~~''' manages~~ the ~~file select~~ screen.	+	== 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.
