Atari 7800 Source Code Rescued

Atari released the source code for the 7800 console and games.

For developers, the recently released source code of the Atari 7800 ProSystem OS and many of its games may seem a bit too late. After all, a good deal of the compiled game ROM dumps can be found online. However, Atari is offering the code uncompiled in addition to a few development tools for interested developers. With Ms. Pac Man, Dig Dug, Robotron 2084, Centepede and nine other games available to download, programmers learning the trade may get a kick out of how Atari created the 7800 versions back in the mid-80's.

As stated on the Atari Museum,  the original source code was recovered from Atari ST diskettes that were thrown out in the dumpster behind the Sunnyvale, CA Atari building (recovered at 3am no less). Along with the games, Atari provided the 7800 base operating system (NTSC), the PAL operating system, the development system, and the animation tool in separate Winzip compressed files. The company also provided the original Joust source code from the classic Atari 2600 console.

"Hey! That's my code!" said Jeff Bell over on Reddit, seemingly ecstatic that his original programming was still around twenty-six years later. "I worked on Robotron in the Summer of '83. I was going into my Junior year at MIT, and I was working at General Computer Corporation in Cambridge. The next summer I worked on Rescue on Fractalus. Then Jack Trameil bought Atari and it all ground to a halt. It was 6502 assembly. There was 4k RAM, and carts could be 16K or 32K. I'm not sure how you would run it without a Maria chip emulator."

The 7800 ProSystem was Atari's third home gaming platform, following the unsuccessful 5200 and the highly popular 2600. The Atari 7800 tried to regain the company's stance as a leading console manufacturer, however eventually trailed behind the Nintendo Entertainment System.

Who's Atari?




"original programming was still around twenty-six years later" That's why you haven't heard of them XD

Yay, now there's more fun to have with a game's source code than with the game itself :D

My 7800 is still hooked up. I play Dig Dug, Donkey Kong Junior, and yes... Robotron 2084. I'm not very good at Robotron though...

Back in the day, there was Atari and Commodore and everyone else was jealous.

Don't be haters! Much respect!

I hear it's filled with cocaine and puppies. That's probably why he wants inside.

This is great, and would be an awesome example in a game programming class.

I thought it was funny because you mentioned the PS3, because the 7800 was basically Atari's PS3. I'm sure the die-hard atari fans defended the 7800 just as thoroughly. It had five games worth buying the system for but everyone else wanted an NES.

Considering Atari got delisted from the stock exchange last year, their last big game, Alone in the Dark, was an over-complicated hard-to-control piece of garbage and that they lose almost as much money every year as they are even worth, it amazes me that their 66 employees are sticking around. I really don't have any idea why they're still in business.



Umm, that is not the same Atari. The original Atari closed up shop in 1996. The Atari name and assets were sold to Hasbro Interactive in 1998, which in turn was bought by Infogrames in late 2000/ early 2001. That is the current Atari that you are referring to.

The article is not clear or complete on this issue, but the disks in question were found back in 1996, not recently. Not sure why they (Atari Museum) have been sitting on them for 13 years. Perhaps there was some legal issue involved.

I used to dump 2600 cartridge assembly code using the Apple II+ Monitor by hot-plugging a home-made cartridge adapter. The ROMs used an inverted CS, so I had to wire in a 7404 inverter. I'd love to see the source to compare against my old printouts, if I can find them. I don't think I dumped Joust, though.

so, anyone know (w/ software) how to run these or do we need a 7800?

Ye the last aitd game was shit, but their earlier stuff was great. I remember ripping the soundtracks from one of the old aitd games (the one where you had to die to complete the story line) because the sound was great.
Anyway atari is an important part of history. But that's all they are today. History.

since when was alone in the dark ever a good game? ;)

& lol @ -20 for the first reply!

I forgot which of these atari home consoles were good, the 2600 was crap. colecovision was a lot better. my neighbor had a game called food fight on his atari but apparantly it wasn't a 2600 since food fight wasn't on that one..so not sure which..

Since the second one ; you may not like it, but you don't seem to like much anyway.
