papyDeck - Open-source Lua console with genlocked RP2350B
Show HN: Three genlocked RP2350B make a console – 3k sprite pixels per line)
papyDeck is a 60mm square open-source console where every game is a readable Lua script you can edit on the fly. Powered by three genlocked RP2350B chips (six Cortex-M33 cores), it delivers 640×480 at 60Hz over HDMI and 3,000 sprite pixels per scanline—roughly twice a Neo Geo. Games are plain folders on a micro-SD card; a sandboxed VM catches errors with line numbers. The same core runs bit-for-bit in a browser simulator, so you can try it instantly. Hardware is CERN-OHL-P, firmware MIT, with repos opening soon.
papyDeck plays like an arcade machine and opens like a text editor. Every game on it is a Lua script you can read, change, and rewrite — including the ones somebody else wrote.

Love the idea, hate the presentation. Also, wasn't able to find the simulator link, is the simulator not publicly accessible?
Also, one friendly tip - if you are EU-based and plan to sell the hardware, drop the ESP32/wireless. Yes, that would mean no wireless pads, but it will make regulatory compliance a lot easier. Maybe replace with a breakout socket (not sure if that is allowed).

So, why are there 3 of them? I can make several guesses but I don't see any concise answers on the page.
