Notes

main PCB is marked: "900T.C"
piggyback PCB is marked: "LC" (it's Italian for "Lato Componenti" = Component Side)
piggyback PCB fits into main PCB @ 8l

This board comes from the same (unknown) manufacturer as Venture (version 5 set 2, bootleg)

update 20080806: Redumped 1 EPROM, previous dump was bad.
It looks like it's identical to version 4 already in MAME, but with different size EPROMs.

update 20170514: I found a second PCB for the same game. I can confirm it was manufactured in Italy. Full redump.
