I can confirm the floating fuse in Sasha's Shooting Gallery. Saw it today on the PS2.
A glitch I had was Raz getting stuck on the path to the elevator up to Dr. Loboto's ladder. On the right side about halfway down. He sank ankle deep into the floor and moved like his ankles were caught. Had to use the bacon to get out.
An easter egg: when Agent Cruller's asking Raz if he's ready to be his agent, and slapping him when he says no, Cruller's looking up at the conversation choice balloon to see the answer as you make it.
