Terimakasih (and others interested in the glitch):
>Sorry, May I ask anyone to explain this glitch?
When you have full speed you begin to flash and become partially invincible, and you can perform a ram move. Usually, when you hit a wall or slow down this status disappear. If you ram Draygon while in this status and he dies, Samus stops but the game forgets to set her status back to not-flashing speed, because she never hits a wall. Samus will now continue to flash until you ram again or run.
In this run, this is used to fly trough an area where you normally can not get enough speed to go into flashing mode.
More info available at the Glitch FAQ for Super Metroid over at GameFAQs, if you're interested.
>Another Words : I wonder that why you think so.
I just think it is very impressive that you can make videos of high quality in very short time.

>I had merely noticed the save slot was present so a savestate had been used.
"Save slot present" does not necessarily mean "played from save state". An SMV can also start from SRAM, which could include a save slot even when the game is played from reset. I don't know if this movie runs from SRAM or from savestate, though. Some hexing hacker can probably tell us.
