DSFIX is the MultiTOS Dosound() Fix v.1.0 by Scott Sanders (the author
of "The Atari Compendium").  MultiTOS Dosound() fix makes an
undocumented function of the TOS call Dosound() work under MultiTOS.
Aladdin (and maybe other programs) use this method to determine whether
a FM sound is already playing prior to playing their own sound. This
feature was never documented by Atari and went away in MiNT v1.00-v1.08.
This patch program catches this call and mimics the undocumented
behaviour to prevent Aladdin (and others) from crashing.  Docs included.
