GlitchNES - Adjustable Delay

Modified version of (the great) GlitchNES. Got annoyed trying to shoot video and use the controllers, so I dropped it in my Panavise Jr, hah! Drilled an enclosure with a bunch of holes to hold some pots and switches.
Single pot through Arduino board connected to the second controller port, the delay length is determined by an 8-bit value. You get some really cool glitches when you bring it up slowly. Needs some work with making the knob more "linear" (you can see that the speed ramps up kind of quick at the end of the turn). That means I have to start counting cycles.. ugh. Maybe I'll shuffle the palette with the second knob.
