I use iDeaS emulator. It works fine with this game. The emulator can
be downloaded here:

I have only tried the English version. Don't know if other language
versions also work.
And for the touch screen function, simply use your mouse and hold the
left button.
Playing with a real NDS will be easier. But if you just want to have a
try of this game, this can be an easy way.
I am not the one who upload these. So download at your own risk. :P
