There's just a few more
a Mystery Galaga ship (between Xevious and Galaga'88)
A fat pink cute'm up ship (behind Twinbee)
a cool little ship (in front of Moon Cresta)
a random jet (behind Zanac)
a retro looking fighter and some kind of pod-ship (below Truxton/Tatsujin)
and a weird squat ship (above In the Hunt)
