Hi!
First of, let me congratulate you for developing the best DS emulator out there.

Now with the problem... I downloaded the Japanese version of the Kira game, and it runs very good in Desmume... but it has some issues with transparency. Let me post some pictures to show you what I am talking about:

It shows a black background where it's supposed to be transparent. I hope you can help me on this ^_^
