Oh, one thing i did learn from this: Those GroovyGameGear CLASSX buttons with leafs, and GGG Leaf stick are AWESOME for playing DK, needs a 4-way restrictor, but whatever...   I can't wait for my actual DK stick to get here.
The Classx buttons combo and Nintendo joystick is what I have in my FIF Jr cab.  Best combo of joysticks and buttons Ive used so far.
And dont worry about the tupperware setup.  Its what Im using right now as a test bed for controls.  I might go with a wood built test bed but cant see why I should when its only for testing.  
As for you being a 'ginger'...Somethings cannot be forgiven. 

And why are you showing two builds in this thread?  Isnt that like illegal here and stuff?
