CHIPnGo VS PicoPico

CHIPnGo A custom-built CHIP-8 hand-held gaming console powered by a STM32 microcontroller.

It's essentially complete now (other than some planned firmware tweaks) and you can check out the source code on GitHub. You can also see a video if it in action here.

I ask because I recently made a console for CHIP-8 which is an old 8-bit “fantasy console” by writing a CHIP-8 emulator for a STM32 MCU. So games still have that 8-bit limitation like you’re going for but the STM32 has a bit more power than actual 8-bit MCUs which is useful for working with the display and stuff.

Now that I have a nearly complete prototype for my CHIP-8 game console that I've been working on, I wanted to attempt to create a custom PCB to truly make it portable.

A couple months ago, I decided I wanted to learn more about embedded software development so I thought it would be cool to port my emulator to a STM32 MCU and try to build a handheld game console since CHIP-8 never existed as an actual standalone physical machine. I have a working prototype and the firmware (which I wrote from scratch so it took quite awhile to get right) is basically done (though I will likely do some refactoring and add a bit more robustness) which can be found here. Next step is to design a PCB and add battery power to have a no-shit portable game console.

You can download the cart here (the 3dsx file). If you have homebrew launcher, give it a try! As I said before, consider this broken/alpha. Bunny, Valdi and Celeste are mostly playable

This is a work in progress build of Pico-8, running on an ESP-32 (with 4MB PSRAM) The code is on github. There's no music support, audio kinda works. There's an SDL backend to test the implementation on PC

A handheld, esp32-based implementation of the pico-8[0] console. Basics work already, sidetracked into writing a terrible Lua to C++ compiler to squeeze some extra performance out of some pathological-case games.

This looks excellent! I'll definitely try to learn a bit of what you've done

I'm making a similar project; a handheld Pico-8 console: https://github.com/DavidVentura/PicoPico/ although currently I'm stuck in the process of writing a half-working Lua-to-C++ compiler

I saw Pico8 a while ago and really liked it! Now I'm trying to make it "real", by creating a physical console that implements the API: https://github.com/DavidVentura/PicoPico

It's heavily incomplete, but it runs "Celeste" on an ESP32. Some small games also run in the Raspberry Pico (RP2040), but it does not have enough RAM for medium-large games.
