Independent homebrew developers such as Matthew Kiehl continue to push classic hardware. Check out this Shadow of the Beast proof of concept he has created for the Intellivision console. Sure, it is not as graphically impressive as more powerful platforms, that is a given. What is awesome here though is just what he has gotten working so far. This is in IntyBasic too, not exactly getting close to the silicon here.
