thanks u_rebelscum, but i still have 2 questions.
1) i have win xp. is there anything i can do to use even 2 tbs?
2) when you say *redrill the top TB mounting holes a little bigger* does that mean on the actual TB case or the wood it is mounted in?
1) Learn the new winXP API called "rawinput" and "rawmouse" and try to add it to a compile yourself mame.

Or wait until I get a winXP computer plus time and add the code to Mame:Analog+.

Besides not having XP, I'm currently spending most of my free time trying to copy a busted pole position cab

. So you'd have to wait some.

2) I mean enlarge the four holes on the actual TB case by ~1/64" (~0.40 mm) to ~7/32 (~5.56 mm).
Sanding the paint off happs mounting plate kit "nuts" (the four round tubes with threads inside fused to the underside of the plate) might do it instead, since the difference is so small.
If you use the plain plates that need carriage bolts heads sticking up on top, no need to redrill.
