Who runs this game / what are the rules / who is in charge? Basically this is one of my all time favourites and for the first time in a long time I see speedrun.com times for some level that are totally beatable, so I might start running this one :)

Questions:

Which versions of the game / with which configurations are acceptable for a run to be acceptable.

What must be supplied for a run to be accepted. Is a simple "twitch-like" YouTube recording of the run enough?

What timer do we use? I see that in both steam supaplex and original supaplex, there is an in-game timer that shows level completion time after finishing a level, with seconds resolution. Based on my testing that timer seems to be wall-clock time, as opposed to something like "cpu time" or "game-logical time". So for steam version where speed is adjustable, it seems to make sense to always use fast speed (of course :P), although that seems slightly slower than original supaplex over dosbox with high enough cpu cycles for the game.
