How to use 8-bit parallel display on STM32F4 for Arcade?

Has there been any successful attempt of using 8-bit parallel connection for an ILI9341 with an STM32F4 board with arcade bootloader?

The document suggests using parallel connection for faster FPS on the display but I have not seen any bootloader config that worked, only with SPI using Feather F405 or F411 Black Pill.

Also, there was no definition for the RD and WR pins of the LCD on the configkeys.h to assign these LCD pins to the mcu (i.e. STM32F4) pins.
