Strike Gunner was ported from the arcades to the Super Nintendo/Famicom, although there were a few differences that resulted in the process:
The HUD was changed slightly in the home console version where it was set along the sides of the screen rather than the bottom.
The final boss was completely redesigned in the home console version as well as it being made significantly weaker.
The ending and Credit sequence was changed in the home console version, mostly to utilize Mode 7 effects.
