Wheel set that covers the most systems and roms all at once?

[KillerQ]

Hey All,

       I'm looking for the best way to unify my setup in one fell swoop.  I am not so much worried about themes and videos, artwork, etc - I am mainly concerned with wheel consistency.

        Which wheel set would cover the most systems and, in turn, roms all at one time?  I would guess that the 'original' titles with transparent backgrounds would be it - as that's what i usually see as 'default,' but you all are the experts.

 

Thanks,

 

Matt!
