How do you sort Roms?

[southpaw13]

I am running advance menu with Mame for Windows.  How do I sort out my roms that use a trackball?

Thanks

Haven't used it in a long time - I think therer is a sort category called "other" that you can specify what it is - for example map "Controller" to it then sort on it.  I just can't recall where you do that exactly.  Must be in advmenu.rc somewhere - look through the docs they have most of these things explained.
