Trace Memory for the DS: Anyone knows how to blow the dust away from the...

[MKS]

...painting in the storage room? Alright. I looked up all the guides that I can search for in the net. I asked a person that beat the game in YouTube and he/she never replied. I tried letting the rushing wind blow my DS microphone while sitting in a running car with the window opened by an inch. I tried using a hair dryer since a guide author tried it and somehow succeeded in doing so. If you are one of the gamers that beat this game or if you saw someone that was able to clear the painting by almost destroying their lungs, please answer. Thanks...
Oh, I forgot to mention this. Yeah I did go to touch screen version (the one with the painting covered in greyish-blue dust). But I can barely see a difference as I blow. Is there a certain way of blowing it or do you guys think I need to use another DS?
