Is this possible with official MAME? (analogue controls)

[Gradius]

I like two player games and I love the possibility of using my two usb mice as independent device for lightgun games, and two player games using spinners. I can do this with Analogue MAME. Sometime ago I asked about any chances of doing this (or implementing this feature) in the official build of MAME. Someone told me that you can do it with windows98, remapping axes (). I suppose he/she meant using two spinners, for instance, telling mame to use x axis for player 1 and y axis for player 2. But that's not my intention, as I think I've made clear. That would work for two spinner games, but not for lightgun games. I need two independent mice working sepparatelly. MAME Analogue can do this. Can official MAME? If not, any idea why this has not been implemented yet? Maybe because Win98 is the only SO that can do it, but as it is obsolete and few people uses it, noone is interested in adding this feature?
