 ## Config Defines
 #define the following in `UNIVCORE_CONFIG.h` to alter specific things.
 - `UNIVCORE_TEXT_BUFFERED` to have the text be first rendered to a buffer before drawing to the screen with Font::update()
-- `UNIVCORE_TEXT_PALETTES` to set custom text palette names (comma separated)
-- `UNIVCORE_TEXT_DEFAULT_PALETTE` to set the default text palette name
 - `UNIVCORE_3DS_SIZE` to make all X and Y positions use the 3DS resolution
