[PATCH] gamecon.c change for SNES controller (fwd)

[James S. <jsi...@tr...>]

Patch for the SNES controller attached to a parallel port. I don't have
this hardware so please test it.

>The old code was giving the same values when you pressed right or left or
>when  you pressed up or down. The new code have been done to not use
>expensive codification (i.e. multiplication).
