I received these today.

 

Three of them read pretty well

 

Karateka Atari 85-08-30 Jordan's.atr - 1 error sector

Karateka Atari 85-09-08 Jordan's copy with cheat keys.atr - 6 error sectors
Karateka Atari 85-09-15 Jordan's copy.atr - 1 error sector
 
Two of them, the music development disks, I couldn't read at all, just failed on sector one. I'm wondering if they are Apple ][ disks, and will check that theory out later.
 
The ones that I could read do boot, but I couldn't get the guy to go much other than kick and hit in place. Maybe this is before walking was programmed in? Or maybe I have no idea how to play this game.
 
Please play with these and report back!

"Atari Karateka Music Development Disk backup" is perfectly readable on my Apple ][. (The other copy of the Music Development Disk was not readable at all.)

 

Apple ][ DOS 3.3 disk image attached.

I played the first one all the way through.  The opening music was a little different.  Also, the enemies seem to be a little too aggresive in a way that makes beating them easier.  Akuma was about the same and yes, Mariko will kick you in the throat if you walk up to her in fighting stance.  Otherwise, it all seemed the same to me.

Woo! I got the source code off the Apple ][ disk as PDFs. This is assembly source for S-C Macro Assembler for the Apple ][, which apparently cross-compiles to the Atari 8-bit.

I got a 100% read of the the version with cheat keys enabled!

 

Use this version instead of the one from yesterday.

 

So far I've discovered that control-R advances to the next level. There should be another code (at least) to drop the opponent's health.

 

(The Apple ][ version with cheats (https://archive.org/...a_Cheat_Version) has two cheat keys:  control-D drops your opponent's health level to minimum, and control-] advances to the next level. )

 

Share what you learn.

The source code from the Apple II disks are exactly what it says on the label - all the music code for the game, and some of the game setup code.

 

Do you have another Apple II disk lying around with the source code for the game's main loop, and graphics support code?

 

Clever work getting the source code out as PDFs.

Pressing N reduces an enemy's energy to one point.

There are no other cheat keys.
