Genesis controller versions.
Well I was doing some work on this Genesis controller today when I happened to notice something mildly interesting...
It seems that not only do original model 1 Genesis consoles have two shades of grey on their logo, but some old 3-button controllers do as well. I also noticed (some time ago) that older controllers have red ink applied to directional arrows and the indented 'A', 'B', and 'C' on the trigger buttons. Newer ones move "trigger" from above the buttons to below as well.
So what I'm getting to here is- is there any preferred controller version like the Genesis console, or are they all more or less the same? (I know I prefer newer ones because I wore my old ones down to the marrow)
