it2snvgm is a command line tool to convert specially formatted Impulse Tracker IT modules to VGM files targeting the SN76489 sound chip used in the Sega Master System. Most chips have too many features for this to work very well, but this one is so simple that it was pretty easy to make a converter that produces VGMs that sound nearly identical to a properly configured module. See the readme in the repository for details.

Here's an example input IT and the VGM it converts to.
