Devil May Cry- "Witch Doctor-D#2" from "Zero-G: Cuckooland 'ghost in the machine'" was used in 1.18 "ST-04 (古城地下ステージ)" (0:14)
- "Is that the Door-G#3" from "Zero-G: Cuckooland 'ghost in the machine'" was used in 1.18 "ST-04 (古城地下ステージ)" (0:26)
EDIT: Whoa!
Knife Edge: Nose Gunner- "Riff 04 31-06" from "Sounds Good: Methods of Mayhem" was used in "Path Select" (not on any official soundtrack)
Didn't think I'd ever find a sample from such an obscure N64 game.
EDIT 2:
I also found a sample from Skinned by Zero-G (SYNTHPADS_OS_SOUND94_SK) that reminded me of a couple of tracks, but I guess it's not the sample.
Ico - Shadow (0:00)
Devil May Cry 2 - OVERTURE (1:13)
