[Pyzzle-users] Fw: Pyzzle -- Protection against pygame.mixer is None

[Andrew J. <an...@la...>]

Cool nuts people.

Fábio Dias drooped me a mail with instructions on how to patch pyzzle so it
can run without pygame mixer being installed. This could become useful for
people who have no SDL sound support on linux or other platform but still
want to work with Pyzzle.

His original mail is below and is fairly self explanatory.

So thanks Fabio for the code or rather commented out code. (-:
