The rules only state to finish the game as fast as possible, but do not state where time should start/end and give very little information about the run itself. I wish to speedrun this game soon but I cannot begin until I know where time should start/end and if anything is disallowed etc.

Hello. I've already made a speedrun of this game and once the only moderator accepts it, they'll mod me. I plan to fix up the board significantly including adding more rules and all categories. If you happen to run the game for the PS3 or Wii, time it as so.

Start from your empty file. Timing begins when you select start as you'll jump into the story immediately. Timing ends when you hit Dr. Blowhole with the 3rd laser in the 20th level "Showdown With Dr. Blowhole".

You can look at my run for reference. (But it isn't too good; I plan to improve.)

There's also the Xbox 360 version, but I don't know how that one works in full; so afraid I have no information on it.

Thanks for the information. Also, is there a particular version that is better? I want to run it on Wii as I don't have a PS3 and I tried to emulate the game but it was very laggy with many visual bugs.

I'm not certain myself. The Wii version should be fine for you, though I haven't been able to obtain that copy yet. There shouldn't be much difference between them, outside controls, from what I've seen. I also don't plan to allow emulation. The game is very static with its settings so I don't want to risk unfair advantages.
