Ace Attoney - Rise from Ashes

[BlackPantera]

in this episode i have to take fingerprints with powder. as game wiki says:

When the protagonist comes across an object with possibly important fingerprint evidence, a close-up of the area is seen and then the fingerprint dusting mode begins. The stylus is then used to dust an area of the touchscreen, which appears green with blue grid lines, with powder, and then the player blows into the microphone to blow off the powder.

so? does anyone know have to do it? may be there is some code for this or smth I don't have a microphone. So I'm stuck =(((

Unfortunately, you really NEED a microphone to continue the game. Try to buy one.
