Replacing isAlive with is_alive
solarwolf fails to start because of an AttributeError: Thread object
has no attribute isAlive. The function was removed in Python 3.9. The patch
replaces it with the new one is_alive().
respecting sound settings when playing game start sound This patch fixes the following problem. . When starting to play, a whip sound is played on repeat until startup is finished. Because of this "playing on repeat", unlike for every other sound, the snd.play() method supporting sound levels is not used, what leads to both whip being louder if SFX settings are low and still playing, if SFX are disabled. . Thanks to Daniel Watkins for providing the patch this patch is based on.
