Ok, this is rather stupid... 'cuz I was bored... But still, worthe a try. Here's two things you can do.
1.) You're gonna need your copy of Zelda:OOT, and anything that has Stairway to Heaven by Led Zepellin. Alrighty... Beat OOT, and wait for the credits. RIGHT when the screen darkens for the credits, start playing Stairway to Heaven, and enjoy... It's not nearly as cool as the "Dark Side of the Moon" playing to Wizard of Oz, but still pretty... creapy. Makes me wonder... :eyebrow:
2.) Ok, you're gonna need a copy of Castlevania: Chronicles, and Metallica's "Ride the Lightning" album. I did this cuz I thought Chronicles' music, well, sucked. Here's the tracks you can play for each level...
level 1. "Fight Fire with Fire"
level 2. "Fade to Black"
level 3. "Ride the Lightning"
level 4. "For Whom the Bell Tolls"
level 5. "Creaping Death"
level 6. "Escape"
level 7. "Trapped Under Ice"
level 8. "Call of Ktulu"
...as you can see, this is what spare time brings to me... Enjoy.
