I messed with game controllers for a while but never found software allowing me to set the analog stick sensitivities to different values. It probably exists but I just gave up. The game controller was OK for 4-tabling but just didn't really move fast enough later. I'm sure some autohotkey scripts for jumping would fix that, but meh. Now I go with a trackball and separate USB numberpad. The numberpad is really great. I also ordered one of
these for my 2001FP. I'll let you know how it works.
