Double fire joystick test

* * * DUAL FIRE JOYSTICK TEST * * *

A tool to test joysticks doesn't have to be boring, so I put animations and sid. 

This program  in particular is intended to test dual fire buttons custom  joysticks, like the ones made by my friend La BayA Retro Marketplace. 

When you press the  fire that goes in port 2 it changes Pac Man colour, when you press fire that goes in port 1 it changes the joystick colour, through the dual port adapter from La Baya.
