Update the Firmware on Your Atari 2600+ (5-10 mins)

Task: Update the Firmware on Your Atari 2600+

Needed: Atari 2600+, web browser

Time: 5-10 minutes


I have previously posted about the modern Atari 2600+ console that plays original 2600 and 7800 cartridges through emulation. I nice feature is that it can be connected to an LED screen through HDMI. Unfortunately, when the 2600+ was released in 2023 it wasn’t compatible with some old games including Donkey Kong Jr. and Robot Tank and some newer games such as Circus Convoy. The good news is that there have been several firmware and emulator updates that resolve many of the issues users have encountered. I recently updated my 2600+ without trouble using the instructions below.


Before you begin, you will need to download the latest AtariDumper software and update file provided by Ben from Plaion in this January 24, 2024 post on Atari Age.

I successfully followed the detailed and easy to understand instructions provided on Atari Age by user Ben from Plaion. First, scroll down to the bottom of the post and download the additional files DriverAssistant and RKDevTool. There are four files in total including the two from just above.

Once the files are downloaded, you are ready to follow his step-by-step instructions. His instructions will allow you to:

  1. Update the dumper chip using the Dumper Tool
  2. Update the Windows drivers using the Driver Assistant
  3. Update the emulator firmware using the RKDevTool software and the update image

This whole process took me about 5 minutes. When I finished and rebooted the 2600+ I could see the version was now 1.1 with Stella version 6.7.


I needed to do this update because I wanted to play my new Alien Abduction game from Audacity Games in HDMI using the 2600+. It did not work with the stock 2600+ firmware. It worked fine after the update.

There will likely be new firmware updates in the coming year or two. I recommend searching Atari Age for the latest update files and instructions.
