After a quick search, looking at one such controller [0], it has a 24mhz CPU w/ 16KB RAM and another I came across that has 32mhz CPU and per doom minimum requirements @ 66mhz CPU and 8MB RAM[1], good luck on that. It's been ported to some pretty weak embedded systems before but maybe someone will eventually prove me wrong. 0: https://www.globalspec.com/Industrial-Directory/nand_flash_controller https://www.globalspec.com/Industrial-Directory/nand_flash_c... 1: https://www.sysrequirements.com/game/doom https://www.sysrequirements.com/game/doom
