All Your Protos Are Belong To Us!


Ok wrong series, but the name is still quite relevant.  As many of you know, the 7800 version of Impossible Mission is best known for, well, being impossible!  Due to a bug the released version of the game is indeed impossible to beat, but did you know that a fixed version was made but not released?  Check out the new Impossible Mission page for more details.


Monkey Music is the original unreleased version of what eventually became the equally unreleased Grovers Music Maker.  While the prototype has been known to exist for many years, the rom for Monkey Music has not been made public.  This has finally been rectified due to the generous efforts of John Hardie who was able to locate the rom in his personal collection and has released it for all the enjoy.  Be sure to check out all the new info on the Monkey Music page as well as a completely overhauled Grovers Music Maker page.


One of the more interesting discoveries from the Atari CED In-House 2nd Quarter 1983 promo documentary was the presence of a completely new and unknown Atari 5200 game.  AtariProtos has been able to gather some information about this game and how it would have played.  Unfortunately the name of the game is still a mystery, but it's possible that it never was assigned an actual name.  Be sure to read all about this fascinating 'new' discovery.

WIP Madness!

Several years back a video surfaced of the Atari CED In-House 2nd Quarter 1983 promo documentary.  This video shows off games being worked on at the time for the Atari 2600 and 5200, many of which are in various states of development.  I've decided to make new pages showing off these WIP versions, even though actual prototypes have yet to be found. 

Atari 2600
Krull, Bugs Bunny, Xevious

Atari 5200
Pengo, Tempest, Xari Arena, Sport Goofy, Road Runner

A Plethora of Updates

Thanks to the efforts of gaming historian Frank Cifaldi, was gifted a large number of Atari 2600, 5200, 8-Bit, and 7800 prototypes to review.  These prototypes came from the collection of a reviewer and seem all be from the years 1983-84.  While most of these prototypes were the final versions (not surprising given that they were review copies), there were a several with some differences. 

One of the most interesting things about this collection was the presence of several early Atari 7800 prototypes.  As most people are aware, Atari 7800 prototypes are very uncommon, so it's a rare treat to come across so many at one time (and for early titles too).  This update also includes a new earlier version of Astrochase and some new information on the MindLink game Bionic Breakthrough thanks to the efforts of Thomas Jentzsch.

Check out the following new* pages and expect more Atari 7800 reviews to come soon.

* The amount of 'new' may vary.  Please consult your doctor before reading.  Side effects may include disappointment, confusion, and an overwhelming desire to fire up that old Atari again.

Rescue Mission & Ballblaster

Although AtariProtos has reviewed WIP versions of both Rescue on Fractalus and Ballblazer for the Atari 5200, we have neglected to take a look at some earlier betas of these games for the Atari 8-bit computers.  These betas were pirated under the names Rescue Mission and Ballblaster, and feature some interesting differences.  Be sure to check them out.


AtariProtos is happy to announce a review of Astro Chase for the Atari 2600.  A fairly faithful port of the Atari 8-bit/5200 original, the 2600 version is just as much of a joy to play as its more flashy cousins (take that as you will).  Head on over to the new Astro Chase page and check out the review.


There are three known prototypes for Elf Adventure, but the earliest version always appeared to be a bad dump.  However thanks to the generosity of John Hardie we now have a working copy of this rom.  So go and check out this new version and see how this sequel to Adventure began.

On a side note, 2022 marks the 20th anniversary of!  Thanks to everyone for reading.
