Another World was programmed on AtariST. It can be a direct conversion since based on the same code.
No Second Prize was programmed on AtariST, too.
Double Dragon 2 seems an AtariST 1:1 conversion.
I believe that games produced by Psygnosis and Core (Leander, BloodMoney) are not direct conversions AtariST->Amiga, maybe Amiga->ST ? =)
Fire & Ice seems to have been developed using the features of each machine. (anyway STE should have blitter and hardware scrolling).
certainly, GoldenAxe is NOT a direct conversion.
I believe the same for CannonFodder, Lemmings, Lotus 1/2/3, Sensible Soccer, Stardust, Trools, Zool, and Ghosts'n'Goblins... they are NOT direct conversions, I suppose...
I have to check these:
Formula 1 GP (Microprose)
Super Cars 1/2
