TMNT,Bad Dudes,Two Crude Dudes,Raiden 2.
I cant think of too many of the other "major" shooters,because at the time,it had ports of all of them about except for R-Type 2 and Gradius 3.
It had Hellfire,Zero Wing,Raiden,Gradius 1 and 2,Salamander,Parodius,Air Busters,Side Arms,Forgotten Worlds,plus more Im forgetting for sure.
Yea your right about the lack of Final Fight,should have been ported over.As it stands,the X68000 and Sega Cd are it for full arcade type port.
Snes as usuall sucked on that port.I heard the GBA port was good.
