SMTC was intended to be a clone of Super Metroid on the PC (Windows).
SMTC was originally developed by a small team and at the time I got these files (many years ago) the developers had already stopped development. I extracted these files from some backups and uploading to srchub as a "permanent" home.
Unfortunately, I do not have the original source.
