This is the source code to the unlicensed Super Noah's Ark 3D SNES game by Wisdom Tree, known for their unlicensed NES games. The game is notably "the only commercially released SNES game in the U.S. that was not officially sanctioned by Nintendo", as well as using the same game engine for the Super Nintendo version of Wolfenstein 3D under license from id Software.


I bought this off of eBay in November of 2018 and got 4 diskettes and an official seal of authenticity (deep irony) for the disks on official Wisdom Tree letterhead. The disks were zipped using PKZIP, an old version that split it across 4 3.5 inch disks. This was a huge pain to unzip, given no modern tools support this specific format and required old software on old hardware to successfully extract. The disks were zipped sometime on of after November 13th 1994, 10:31AM, which is the latest date on any files in the disks. The original files from the diskettes are included as well as an extractable archive of the contents. All files are available on GitHub as well.

Interesting Contents

There were a few notable items in the archives I will share below. First (not below) is the full set of tools provided by id Software to extract and repackage the contents of Wolfenstein 3D, as well as the C source code for it.

There are several emails from John Carmack himself as well as code he wrote for the sole purpose of cloning Wolfenstein. The sound driver was written by John Carmack and Rebecca Heineman credited as Bill Heineman. If you dig in and find more interesting items, please update on the Super Famicom Development Wiki and TCRF Super 3D Noah's Ark (SNES) article.


Rebecca Heineman: The sound code was originally written for RPM Racing, using the Apple IIgs Merlin assembler with macros to build for the custom Sony SPC700 CPU. It was improved over time for Wolf3D.

Rebecca Heineman: Kewl. I found the source to my old audio tools for the SNES. At the time they were written, I had no docs to the SNES because of licensing issues with Sony. This code was created by reverse engineering the audio hardware and figuring out how it worked.

Rebecca Heineman: I even learned Japanese, so I could read the patents, Sony docs on the SPC 700 CPU I found "elsewhere" and other bits I could gather to complete the sound driver. Sugoi!

Rebecca Heineman: I think for the xmas break, I'll get the game to compile with my current 65816 build tools.

John Carmack: I gave you huge respect for learning enough Japanese back then to get through the tech docs!

Ok, here is the code for the utility that generated SNES sounds (a  
tiny NeXT program).  I wrote this, but only because the original  
development plan fell apart.  I make no claim that the sound code in  
wolf is worth a damn.

I think the sounds were all 22khz 16 bit samples, but it has been a  
LOOOONG time since I looked at that stuff.

I think you have the cmdlib.[ch] files from other stuff.  Here is  
printf ("sndlink 0.1 by John Carmack\n");

printf ("Sndlink (v0.1) by John Carmack\n\n");

; Id's SNES sound driver - decoded from 'driver.s' provided by Id in
; an 'encoded' state (simply and each character with $7F to get in
; ASCII range - for some reason this was the ONLY file provided by
; Id that was encoded...).  It includes 'SPC700.MACS' which was not
; provided by Id but it appears to be only a macro file so the SNES
; sound chip code could be compiled by their regular 65816 assembler!

// JAPVERSION has mission pics instead if briefing

//#define	JAPVERSION

// If PALCHECK is defined, aborts on NTSC version, else abort on PAL

//#define	PALCHECK

Assets and other files all seem in place, as well as some tools I was not able to find anything for online, which I believe could be the iD assembler mentioned in the file above as regular 65816 assembler:
