I'll hopefully add more content and information soon - for now though, this repository just contains the source code and schematics for the demos I showed in my YouTube video here:
The demo source is in the src folder and can be compiled through the Makefile, or by running something like:
vasm.vasm6502-oldstyle -Fbin -dotdir src/snake.s -o bin/snake.out
Please see the hardware folder for schematics, BOM, and build notes.
Do let me know on reddit (/u/gfoot360) if you have any comments, questions, requests, or other feedback!
