Need help getting Hotel Dusk to run

I downloaded Hotel Dusk for the DS a week ago and I can't get it to work right.
On No$ it gets to the first level then gives a fatal error
It won't even start on Desmume. I kept fidegting with the options on no Cash but nothing seems to work.
Any advice would be appreciated.

Update to 2.6a, and use NO$ZOOMER. Links can be found in the Common Issues. https://www.romulation.org/forum/index.php?topic=1462.0

Thanks.
