Inspired by this thread, I ran a Summer workshop for a handful of kids who built Pi Pico-based MakeCode Arcade handhelds and created original games for them. The kids had a blast but the ‘3D-printed Game Boy’ models I repurposed for the project were a pain to produce and assemble. To save others grief I designed a new handheld from scratch and documented the complete build the process. You can read the instructions here and download the 3D models from cults3D. If you’re an educator and want a free non-commercial license just ping me.
Here’s my daughter rocking some Jumpy Platformer:
Big thanks to @AqeeAqee and the others who’ve explored and documented the state of RP2040 compatibility!
