I'm finally ready to show you a project I've been working on and off for several months. It's a 8-bit retro video game based on Arduino and ATmega328P. The project is not yet finished -- I'm working on music playback which is still missing on the video.
There is hardly any cycles left during screen refresh.
Still its magical what they did in the 80's with C64, only 1mhz (with the sid chip of course).

That equals to an AVR running at 6MHz and that is fast comparing to 6502s.
