SND file v3 handler

Read SND file, play it, convert it to S3M or MIDI.

SND is a file format for storing NES (and some other console) music (almost) losslessly.

The program converts the SND to MidiS3M with Adlib instruments.
PCM samples are converted into S3M digital samples.
Conversion to MIDI format is also supported, but it doesn't save the PCM samples.

This zip file contains some S3M files generated by sndtool2 (only the instrument list has been finetuned by hand) and one MIDI generated by sndtool2 (not edited).
Note that the S3M files use adlib instruments.
Most mod players are unable to playback them, and most of the rest which can, only use an emulator which isn't perfect.

The program works, but isn't yet ready for users.
Command line options have to be implemented and the instrument type heuristics enhanced.
Three primary goals are:

• To shrink the amount of manual finetuning work needed after the conversion to minimum.
• To produce as exact conversion as possible, without hindering the next:
• To produce as readable and editable conversion as possible.

• opl3emu emulates the OPL3 chip (which is known also as the FM synthesis chip or AdLib). I'm investigating how OPL works so that I could make a good adsr-based instrument detection here.
