if I was you I would go for the orbit 3 , ive got 2 of the original 9090 v1 sitting in the loft with their launch pad controllers ,the orbit 3 can as far as I know can add (expand) the roms of any other emu module , the same as the proteus 2000 and if I remember rightly the “turbos” are expandable as well ,so what ever way you go you can have what ever modules you like all in one chassis
