Mushihime-Sama (2004/10/12.MASTER VER.) ROM

Mushihime Sama is a bullet hell shoot 'em up made by Cave in 2004.
After you start up the game there's two modes to choose: Original and Maniac. Original is the easiest mode in the game while in Maniac the amount of bullets is slightly increased. There's also a third mode named Ultra, and this one is HARD AS HELL! In this mode, the bullets will take like 90% of the screen, so you'd better have great skill at avoiding them, or you'll die in a few seconds.
Unfortunately, the Ultra Mode is locked. But there's two ways to unlock it: The first one is by beating the game in Maniac Mode 50 times using no continues, and the second one is by pressing a button combination that I'm not gonna mention in here.
It's a really cool game overall, so what are you waiting for? Download it now, it's worth it.
