Let me first say that I'm brand new to the idea of speedrunning, but it's been a bit of a growing nag in the back of my head to give it a shot. NGB would definitely be the game that I am most familiar with, so it seemed like a decent place to start.

My questions though, is that I own it on both the original XBox as well as through backwards compatibility on the XBox 360. Is one valid or invalid for speed runs? Does it make a difference to the overall time, or is the run based off of the in game timer? If the run is based on actual time, does anyone know which is better from a load-time perspective?

I'm sorry if these are silly questions, but like I said, I'm new to the idea in general.
