+## Color Themes
+
+To customize your color theme...
+

+1. Scroll through the different color themes with the left and right directional buttons.
+1. Press a non directional button to exit the menu and save your selection.
+
+### Notes On Saving
+
+Better Button Test saves your theme selection using your cartridge's save memory. If your cartridge does not have save memory, your theme selection will not persist. However, Better Button Test _does_ support battery-less saving on cartridges using SST39SF010 flash memory, a relatively popular chip for simple homemade cartridges. This is accomplished by using flash programming commands to alter the rom stored in the flash memory.
+
+If your cartridge does not have save memory, and your flash chip is not a SST39SF010 series chip, you have the option to customize the theme by altering the rom file prior to flashing. To select your theme, change the byte at location `0x7FFF` from `0xFF` to a number between `0x00` and `0x0F` that correlates to the index of the theme you'd like to use.
