Source Code-palooza

[Curt Vendel]

While doing research for the next book - Atari Corp: Business is War, I ran across some source code to various Atari 400/800 games, Donkey Kong, Defender, Dig Dug, Football and Tennis...

 

Enjoy!

Great! thanks for posting.

[Goochman]

Would be fantastic to get some updates to DK and Dig Dug

[Tempest]

Is it the original Dig Dug or the updated '5200 version'?

[+Stephen]

Sweet - thanks for posting.

[idavis]

Awesome Curt!

 

[+Roydea6]

Nice ++++

[+Allan]

Cool. Thanks Curt. Hopefully someone can figure out which Dig Dug this is. At least now we know who programmed it.

That's strange because I spoke with Steve Baker and he said he did the 5200/8-bit version. M.W. Colburn did some other Atari 8-bit stuff such as the Atari 1200XL BIOS, so he was definitly an Atari 8-bit guy. Maybe he 'ported' the 5200 version to the 8-bit? I know I've seen two different people do stuff like this before such as with the 5200 version of Super Breakout.

My gut says this is the original version as I've found references to them working at Atari, but nothing about them working for GCC (who did 5200 version).

[+Allan]

It's a totally different version.

 

Try this program.

Really? Interesting. I'm at work right now so I can't look into this. SCREENSHOTS PLEASE!!!!!!!

[+Allan]

Here's a screen shot.

As you can see it's not very good. I can see why they went with Steve's version. I just wish we could find his finished Stargate that was faster.

Allan

Weird! Yeah it looks like really cruddy, how does it play?

 

I don't know if a 'faster more finished' version of Stargate really exists. I think it's a case of Steve mis-remembering things as the 8-bit port is exactly as slow and they wouldn't have started it until the 5200 version was finished.

It's OK. Not nearly as good as Baker's version.

 

You might be right about Stargate. Not porting it from one system to the other until it was complete makes perfect sense.

Not at all. Sean Hennessy did RS Tennis as far as I know. Is this a different game?

 

EDIT: Greg's name is listed under MODS so maybe he modded the game for the Atari 8-bit? I know they did change a few things (added a trophy on the win screen, removed the 4 player hidden mode, etc.). That would be my guess anyway.

Wow this is awesome. Wouldn't mind seeing a Jaguar version of Dig Dug and Donkey Kong. I think the Jaguar library is covered for Defender, Tennis, and Football.

68000 isn't the same as 6502, ObjectProcessor isn't the same as ANTIC/GTIA.
