I've completed my emu,
but I've found the PPU time & vblank time have problems.
Who can give me a exact DOC about PPU TIME?

You could try searching on both boards (this one and the old one) for answers. You should also take a look at the wiki. If the results obtained do not answer your questions, then you should ask for further explanations here.
