I am not sure if this will be useful to anyone, but I found this on another emulation site which I am a member.

Complete SNES SDK and programming manuals - includes.

SASM SNES DEV tools
SSBUG (Super Nintendo Development System Debugger)
Nintendo's SNES Official Programming Manual
SNES Development Manual (Book 1 & Book 2)
Super Famicom Documents

If anyone is interested in the documentation let me know. I also found one for the N64.

Nintendo64 OS Version 2.0L (PC version)
LFC-N64 (Official N64 Development Libraries and manuals)
Official and Confidential Nintendo N64 Hardware/Programming Manuals
PSYQ and PSYQN64 SDK
Sample source code

Thanks,
Scott
