Wow! how did you come up with that list? awesome!
A program called "sortinfo" will organize Mame's "listinfo" data into a really easy to sort list of games which you can sort by input type/number of inputs/etc. It's not always right, but it's a good start. I also used searches on Klov. Lastly, I played them all to make sure they work right (the trackball games, anyway).
The odd thing is that windows is picking up *one* of the spinners as a mouse, but not the other one.
Currently I have a trackball and the two spinners hooked up, and it no likey.
In Windows 98, if I plug in 2 or 3 or 10 mice (HID mouse devices) into the computer at one time, they will all control the Windows mouse cursor. Therefore, assuming that the Tornado spinners work like generic mice, and both spinners work properly, I would expect that both spinners and the trackball would all control the Windows mouse cursor at the same time.
Can you plug the spinners in one at a time and make sure that they both work (in other words, to test to see if they can control the mouse cursor in Windows without both of them plugged in)? If both spinners work with one plugged in at a time AND 2 will not work at the same time, then I think you need to email XArcade and find out why they don't both work.
I can't even get one of the usb tornado spinners to work...is there a setting somewhere that I need to change?
Like Oscar said, you will need to enable mouse input in Mame.
"mame.exe -mouse warlords". You will probably not get 2 of them working in Mame without Mame:Analog+.
