Joystick input affected by GUS utilization

[ehoughland]

In certain games, the joystick input is affected by the utilization of the soundcard. For example, in Super Street Fighter 2 Turbo, if GUS firmware is loaded with joystick support turned on (/j) AND the card is used by the game for music and sfx, the joystick will exhibit random inputs. If the game instead is directed to utilize another soundcard within the system for music and sfx (in this case, an ESS Audiodrive), the joystick behaves normally.

As an aside, it would be great to be able to use more than four buttons. Loving my PicoGUS otherwise!
