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
