Recently I have discovered several vibrant Colecovision groups on Facebook. I’ve been getting a lot of positive feedback on the #ColecoJam, with 600 likes in one group!

I've been working on Super Game Module and MegaCart support for #ColecoJam. This will allow more homebrew and arcade quality games to be played on this #Colecovision emulator. A beta version is now available at github.com/cogliano/Ada...

Title screen for Dragon's Lair game on the ColecoJam.

Can’t. Stop. Doing. It.

This is very cool!

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.

It was the bundled game when I bought my #Colecovision back in the early 80s. I just recently released a Colecovision emulator called #ColecoJam that runs on an @adafruit.com #FruitJam.

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

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.

The emulator also supports physical Colecovision cartridges.

Check out my credit card sized Colecovision emulator #ColecoJam in my feed.

I would love to see more community projects like this one.

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.

The Fruit Jam now runs a #Colecovision emulator too, with #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.

@cogliano.bsky.socialSep 23, 2026, 2:42 AM

Oh my! Hope you get better soon.

The menu update was the last thing on my to-do list. Hopefully that will be it for a while.

@cogliano.bsky.socialSep 22, 2026, 5:21 PM

Hi Frank! The new button 1 feature should not interfere with the bootLoader's button 1 usage. Claude adjusted its' code for it.

@cogliano.bsky.socialSep 22, 2026, 4:49 PM

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.

Back in the day when defining 256 × 192 pixels as "high resolution" was a valid statement.
