Probably no one will see this for a while, but I was messing around trying to see if I could damage boost up (because the ramp to boost up onto the cart wasn't there in my rom for some reason) and I got this weird glitch:

I think it might have been because of the enemy turning around and basically making a boost pad, but I haven't been able to replicate it yet. I'll keep trying and see what I can do, but I think it might be possible to do this in a normal playthrough, just very tough. I think in order to get it to turn around, you have to turn away from the wall for a frame or two while it's almost directly below you, and it thinks you're on the other side of the "tile."
