In the Japanese version of Trouble Shooter (known as Battle Mania), if you hold the C button on controller two while the game starts up, it displays the game's protagonist stomping curiously on a Super Famicom (the Japanese variant of the Super Nintendo). Apparently the developers were Sega fans, and were annoyed when funding for their game was moved to Nintendo projects, deciding to get their own stab back at them by hiding this screen in the game.
