Joystick potentiometer calibration assistance for Star Wars

Hello.
I am clearly going to need some help if anyone can?
Ive built myself a 1983 arcade star wars yoke with potentiometers for X -Y movements and using the board from an old Microsoft Sidewinder joystick hack. Quite a common build amongst retro DIY gamers I understand.
Following the soldering up instructions on line, the 4 yoke trigger buttons seemed to be directed to the hat controls of the once Sidewinder rather than its true fire buttons. This did mean I could not use the fire buttons to confirm joystick calibration on the PC. However using Virtual Joystick and Universal Joystick Mapper (UJR) I have been able to reassign the yokes trigger buttons to be fire buttons and it seems I have a smooth enough X and Y movement by the looks of the PCs joystick calibration window.
However MAMEs cursor results are far from smooth . Very juddery indeed. Frankly unplayable. Can anyone offer any suggestions whats going wrong?
Obviously ive got joystick settings options all over the place so I suppose I may have overlapping contradictions but I will take it Virtual joystick and Universal Joystick mappers configs are fine as the PCs calibration window shows smooth x and y movements.
Has anyone handy tips for configuring MAME? I know Star Wars 83 is generally temperamental but i tried another cursor based game, Missile Command to be exact and that too is a very unpleasant movement.
Many thanks in advance

Cheers for input guys. Tried the settings suggested in the past, still no change.
Just tried the Star Wars Trilogy game (not part of Mame) with this yoke and its fine. Mame is individually not happy about something with x-y movements. Any suggestions?

I had a yoke reserved during the pre-order period, and then canceled because it was taking longer than I hoped, and I was getting worried. Then at least most of those first batch got theirs. I ended up getting one used, and did an SW hack, and using joytokey I think I got it all working fine. (I ran out of button assignments, though, and bought an AKI to supplement, eventually to phase out the SW with...just haven't done it. I went the whole way initially, buying the plug that connects to the yoke harness, connecting the female side to the SW, because I didn't want to cut the original plug off.)
Except the judder. Guess what? You have to initially calibrate the yoke. On the link below (I simply googled 'star wars yoke calibration') it says it's auto-calibrating, then goes on to say how you can. I had to. Not perfect, but much better. You might have to do it in every yoke game, for example I use it Spy Hunter and Outrun, and Crossbow.
The Star Wars yoke controller is auto calibrating. If you move the cross hair to all 4 corners of the screen, the game does a pretty good job of determining where the center is. In addition to this auto calibration, Star Wars has a diagnostic screen that shows how the potentiometers are reading the controller's position.
