My idea is to create a Pico based computer with 2 Picos, 1 for video/audio output and game emulation, and the other one is used to decode all the user inputs such as USB or controller inputs.
The first revision of the PCB has been completed, but will not be printed until all the details are settled down.

Planned Features:
-Comes with different shapes(Only the PAC-MAN is designed at this stage)
-Very small(10cm*13cm)
-Audio output for speakers or headphones
-VGA and RCA video output(with a switch to switch modes)
-Micro SD card slot for storage
-9 pin ATARI 2600 joystick connector(DSUB-9)
-Reset button
-Power switch
-Can use surface-mount components(resistors, conpacitors), or normal-sized components(Metal-Film resistors, PCB Mount Electrolytic Capacitors)
