First: MAME 0.37b11 and later support the Optimouse drivers.
Are you loading DOS MAME through Windows? If so, then the following may pertain to your problem. It was taken from the Optimouse readme file.
"Windows seems to like to init all pointing devices so they all operate together
this isn't good news as our extended mouse driver will have no mouse available.
Under Windows please make sure you don't plug the secondary mouse until it has
totally finished loading once loaded plug in the secondary mouse windows shouldn't
know about, if moving it makes the pointer move you've done something wrong!"
So, if moving both mice in Windows works, then it won't work correctly in MAME as a secondary mouse in the manner that you want.
Note: Using the Optimouse driver makes the secondary mouse usable by Player 2, so it sounds like you want your trackball for P1, and spinner for P2.
