[Bug 3930] HOMM shows black screen (winmm sound callback deadlock)

So, this is pretty silly, but for HoMM1 specifically, there's a fix... You just
need to install the official HoMM1 patch 1.1 (the intro screen shows it as
1.2): http://handbookhmm.ru/nwcomputing/download/hw9511.zip

Here's the background: HoMM1 uses WAIL (Windows Audio Interface Library)/MSS
(Miles Sound System) from RAD Game Tools for its audio (at least the 8-bit
one). The unpatched version of the game used an old WAIL version, and the patch
updates it to MSS from 1997, as well as updates Smacker. In the Smacker release
notes, you can see some things of relevance:

Specifically, 3.0 g and 3.0 r (which is what the patch ships) fixes deadlocks
and race conditions.

So with the patch, the game starts, the intro cinematic plays, the menu works,
you can see high scores. But trying to launch a game causes it to freeze still.
