Another Code - Close the DS?

[sonstwasirgendwas]

Hey guys!
I've got a problem with the game "Another Code - Two Memories". I'm playing with the No$GBA Emulator and everything works fine except one thing.

In the game there is a task which is in the walkthrough described like this:

"Use the stamps on the book to finish the picture, you will need to press them
somehow. Close the DS and you will have stamped the paper, do it again to
finish the picture."

But... how can I close my DS when I play with the No$GBA Emulator? T.T Is there a possibility to do this or a cheat or something...? Or do I really have to give up the game only because I can't finish this one stupid task (stupidly it is necessary to proceed in the game)?

Thanks in advance for help.

To close the DS using No$gba just minimize it, then restore it. This gives you the same result as closing, then opening the DS. MIKE
