Alright, this is an idea I've been toying with for awhile. It's Kraid's Lair's theme, synthesized, and loopable. It's intended to be a replacement for those crappy sounding midi's that most people use in their fangames.
It's a .OGG file(because .MP3 isn't designed to be loopable, and .WAV is just WAY to big), so you need a plugin or .DLL for Gamemaker, look at the GMC forums or use Google; any other program, I don't know what to tell you.
PLEASE give credit if used, that'd all I ask, just a little "Kraid's theme by Dark__Echoes", that's all. You can even copy/past that, if you're lazy. ;D
BTW, made with FL Studio 8.
