Light Gun Question

[tenex2mg]

Greets all,
  First off I'd like to thank all those that helped me out with my mamewah problem...its working great.  I've been reading abit about these "new" USB light guns and think it would be a great addition to my cabinet.  I noticed there were several types of guns available.  There's a serial version as well as a USB one.  I know the USB is directly supported by MAME while the serial one supossedly isn't?  But I'd like to use two guns (more fun eh?) and the ACT-LABS site says the USB is only one gun....is there a work around past this limitation?  If not can the serial version be used with MAME?
 I know the guns basically emulate a mouse..and have seen a few ports of MAME that supported "dual mice"...is this a viable option as well?


Sorry for such a long post...just wanted to get it all out there :-).


thanx again,
