Video signal generation from a PIC chip

Richard writes “I have designed the hardware of the PIC game system to be able to run severla different kinds of games. It has two standard C64/Amiga/Atari joysticks and video and audio output. The processor is a PIC16F84 running at 12MHz. THe description of the hardware is placed on this separate page as it is the same for both of my PIC-based video games. So far I’ve only made two games, Pong and Tetris, but some day there might be more games for the system.” [via] Link.
