Show HN: Three genlocked RP2350B make a console – 3k sprite pixels per line)
3 hours ago
- PapyDeck is a Lua-based game console with a sandboxed VM that prints line numbers on errors instead of crashing.
- Games are plain folders on a micro-SD card containing a main.lua and art; no compiled blobs or locked cartridges.
- The same VM runs in a browser simulator bit-for-bit, allowing code editing and instant replay.
- Hardware uses three genlocked RP2350B chips (six cores) for HDMI output with 3,000 opaque sprite pixels per scanline and no tearing.
- Current V1 alpha supports HDMI, sprites, tile backgrounds, micro-SD card loading, Bluetooth gamepads, Wi-Fi, audio, and OTA firmware updates.
- Hardware is under CERN-OHL-P, firmware under MIT; repositories will be open for forking and manufacturing.
- The console can list and download published games over Wi-Fi directly onto the card.
- Still open items include HDMI audio, verified leaderboard, and final PCB with voltage supervisor and secure element.
