making the smol-est emulation gamer – part 1

we’re taking a short break from floppy disk hacking (don’t worry, we’re nowhere near done and this will all tie together – promise!) and working on a QT Py gamer backpack we designed. the qt py esp32 pico here plugs into the back to drive the 240×240 IPS display with an SD card slot, battery charging, and an AW9523 GPIO expender for all the buttons. we wanted to make a very smol odroid go-like since that hardware had a ton of support. we’ve found a great open emulation project with a LOT of emulators supported and a very easy-to-understand structure at https://github.com/ducalex/retro-go so we’re having a ‘go’ at porting it over! we had to use esp-idf 4.2 and this is the first time we’ve used raw idf and…we really like it! ninja is such an incredibly fast compiler and we like the ‘flash n monitor’ helper. so far we’ve got the chip booting and the tft is kinda coming up, just need to tweak the init for the st7789 instead of ili9341 – video.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
