How do you hack one mouse for two spinners?

that's essentially what you do.  IRs don;t like heat, so solder quickly.

I’ve seen someone do this but I can’t find it in the examples.  I think you remove the optic pieces from the mouse board, put them on a home built board and connect them with wires.  If someone has any info, pictures, documentation it would be a help.

What kind of spinners are you interfacing with?

www.oscarcontrols.com is selling a Logitech mouse with remote optics for $16.00 which would save you a lot of work.  It's on his order page, I don't think he mentions it anywhere else, yet.

www.cheeptech.com/cuhack.html has pictures of what's basically involved.

Also, if you already have optic boards attached to the spinners, you should be able to use  these hacks http://mamewah.mameworld.net/MouseHack.html and  http://members.shaw.ca/bakaye/tballhack.htm   LuciD has a similar hack on his (?, I hope) site, but I don't have the address handy now.  The advantage to this hack is that you don't have to disturb the original optics of the spinner.

I would try this hack first, since if it fails, you can always attach the removed components to wafer board and use the hack above (assuming the spinner's encoder wheel is similar in teeth spacing to the mouse's encoder wheel).  Actually, before I desoldered anything, I would probably plug the mouse in and hold the mouse optics in the path of the spinner encoder and see how the cursor responds as you move the spinner.

You will also need MAME Analog+ to map the mouse axis to Player 2.  See http://www.urebelscum.speedhost.com/
