This is a compilation of all the SNES SDK (software development kit) samples provided by Nintendo that I could find. I went through many games spotting duplicates. A total of 61 samples are in this compilation.
A readme is included with detailed information about the samples. The tunings txt is inside the samples folder.
For documentation and research purposes, some samples that are already in SMW are included here too, of course you don't have to insert them again, silly.
probably, as I mentioned, these are all the samples I could find/recognize, there may be more because some of them (like the modulated sine and marimba 2) are only found in two games (if you count the burn in test cart and the test program cart as games that is)
