Wells as title says it is really impressive work that is based on one of the smallest ARM Cortex M0 LPC111x microcontroller that is priced around $1. With only few components like resistors, capacitors and crystal it is able to produce 256 color 320×240 composite or s-video signal and 8bit 15kHz stereo audio. Game can be controlled with one analog joystick.
The most fun part is that graphics can be run in 3D along with sound. Source for the LPCXpresso/Eclipse project is posted on https://sourceforge.net/projects/rbox/. Enjoy!
