From the project
RP2350-based retro style game console
This is the 2nd iteration of an ongoing project where I'm attempting to create my own homemade "retro" game console.
The rules are pretty straightforward: 1) No modern ports or protocols (no USB, HDMI, WiFi, Bluetooth, SD cards, etc.) 2) Games must be cartridge based (and must use parallel communication rather than serial) 3) Composite AV only (no VGA, S-Video, etc.)
