This programmer made an app for Macs that would do the little MegaMan boss intro for any program that you start, but didn't bother to port it to PCs. Well, a website called Virtual Constructs just made a PC version, and you can pick it up here!

EDIT: Never mind the "just" part, it was created in 06.

Just make sure you tell it not run on rundll32, every action you take will get interrupted by that stupid 8-bit music.

Thanks for the advice. I was hoping there was a program you could block to keep it from doing that.
