btw, one problem I had..
98 requires you to have a button 1 to calibrate a joystick.  Hitting next doesn't register the difference.
It took me FOREVER to figure that out.  And only found out when I went to Daves site to send him the tech question when I read a warning on his site.  
It worked GREAT on the beta chip set... But when I got the latest version (that seperated the joysticks into two) I had wired all my games to just buttons on joystick one.  And I didn't rewire.  So everything worked in mame (since it didn't care) but I never tried to recalibrate my T2 control panel.... And since I didn't have a button 1 on joystick 2... it wasn't happening... 
But now with a quick rewire of buttons 1 & 2 on joystick 2... All is good
