Happy #Oktoberfest month! This is a card design I did a few years ago for an #accordion themed deck of cards. Bonus points if you can guess the song on the flag.

Welcome to #ColecoJam, a #Colecovision emulator for the @adafruit.com #FruitJam. The project includes the emulator, a cartridge reader and a 3D printed case (video includes title screen in the upcoming release). #RetroGames danthegeek.com/colecojam/
I’m happy with my first attempt at a 3d printed case for the #ColecoJam. It still needs a few tweaks but I’m closer than I thought I would be. #ColecoVision @adafruit.com #FruitJam.
This is really interesting: a recent community project where a #Colecovision "Mr. Do" cartridge was disassembled, enhanced with improved sound, graphics, sprites and more, and re-assembled into a new cartridge/ROM version with the name "Mr. Do Arcade". It also works with #ColecoJam. mrdoarcade.com
The Fruit Jam now runs a #Colecovision emulator too, with #ColecoJam. danthegeek.com/colecojam/

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.
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.
Has been one year already? This week marks the one year anniversary of my initial release of #Zork / #ZMachine for the #FruitJam. It is written in @circuitpython.org and can run standalone or with Fruit Jam OS. learn.adafruit.com/zork-and-the...

Oh my, my @bsky.app feed is lately looking like a flashback to the #1980s. Now where did I put that #HallandOats LP?

WIP: For the next phase of my #ColecoJAM project, I am designing a case for the @adafruit.com #FruitJam and my cartridge reader shield. I started with Adafruit's case design in Fusion and modifying it to fit and look like a mini #Colecovision console.
