Umm... not sure where else to put this, but it deals with the SB3 rom, so...
I was looking around through the compressed sprites of Super Bomberman 3 (haha, as if any of them AREN'T compressed) using VSnes and found this:
If you didn't notice the unused sprites I was talking about, look again, and look until you find them because it should be very obvious to anyone who has ever played the game.
3 frames (there would be 4 total in the animation, as the angled one would get flipped) of Bomberman, with the same movement as if he were hit on the head by a bomb ("dancing"), but... with big heart-shapes over his eyes. O_o I am 100% sure this never occurs in the game. Correct me if I'm wrong; if not, then I wonder what they were for. Anyway, just thought it was interesting.
