Was inspired by the recent Doom on Neo Geo video by @modernvintagegamer.com to get some raycasting working on the @adafruit.com #fruitjam using #circuitpython. Runs about 3 fps on real hardware! github.com/relic-se/Fru...

Adding a screen saver to the next release of #ColecoJam, the #Colecovision emulator for the @adafruit.com #FruitJam. I thought I add this short transition instead of just enabling the screensaver.

Fruit Jam, Zork and the Z Machine
In the 80s before ChatGPT, gamers had another way to have conversations with their computers: Zork and Z Machine games.

WIP on #ColecoVision cartridge reader shield for the @adafruit.com #FruitJam: Success! PCBs arrived, parts soldered and initial cartridge reading @circuitpython.org script works! (I can see the game title in the raw data.) Next up is enhance code to write the cartridge data to an SD card.

I have officially released Moon Miner, an 80s retro styled video game for the @adafruit.com #FruitJam. It is written entirely in @circuitpython.org . Please try it out if you own a #FruitJam (or consider buying one if you don't ;-) . Feedback is welcome. Thank you!

In the latest version of my #Colecovision emulator, #ColecoJam, I have added a logo to the cartridge menu, and now pressing button 1 on the @adafruit.com #FruitJam while in a game will return immediately to the cartridge menu, no reboot required.

I'm pretty proud of how my "Moon Miner" game turned out, from a measly beginning back in October of a square with only vertical movement to a full rotational rocket with missions to complete as well as avoiding volcanos. @circuitpython.org @adafruit.com #FruitJam

A year ago I wanted a "programmer" based on the Adafruit TesterBrains. It needed USB host, a display, buttons, Neopixels, IO pins, SD card support, and sound.
There wasn't a pre-built PCBs so I designed and build my PortaProg XL.
Fast forward and Adafruit's FruitJam would be just about perfect!

WIP: Working on my 3rd screensaver for the @adafruit.com #FruitJam and #FruitJamOS. This one takes an image and converts it into a 15 puzzle display, generating random moves & undoing moves. It was actually pretty easy to split the image into tiles in @circuitpython.org using the TileGrid library.
