Based on work by https://twitter.com/G33KatWork Instructions to get this to work : (do not attempt this unless you're good at soldering/linux/etc) 1. Cross-compile fbDOOM for ARM - https://github.com/maximevince/fbDOOM 2. Put it on a USB stick alongside DOOM.WAD from the shareware release (or full version if you like) 3. Connect a 3.3v UART to port CN1002 on the main PCB (1=3.3v, 2=TXD, 3=RXD, 4=GND) 4. Get Root ( https://twitter.com/G33KatWork/status/1146860035085086720 ) 5. kill rbp 6. run fbDOOM from the usb stick (it gets mounted in /media/usbx/sda1) Hit me up if you want better instructions.
