Man, I really wish I had a better memory, but its been along time since I played this game.

The game was either on the NES, SNES, or Genesis. And I really wanna try to find it again, except, the only thing I remember at all is this:

In the game, I think the boss were all very huge, usually taking up the entire right half side of the screen. And I think their backgrounds were always a solid color, wheter that be black, green, or whatever.

Thats all I remember I think one boss might've had like a glass chest or stomache, and had a heart inside it for a weak point, and possible tank-like tractor wheels to move.

IF Anybody has ANY ideas please let me know... This is driving me insane.
