This is my 2nd post ever!
If this modification works, I will buy one, however, here is my concern:
As I understand it, the Midway/Happs 49 way joystick detects the position optically by detecting the position of the base of the joystick shaft. With the sleeve on the shaft, I think it would alter what position is detected by the joystick. This may just take some getting used to when in 49 way mode, however, with RandyT's GPWiz49, the other DRS modes probably wouldn't work well at all.
FlOyd, can you comment on how your prototype works in the various DRS modes?
Thanks,
