It is a certified emulator provided to developers in Nintendo 3DS development kits. The original emulator was leaked to be the first Nintendo 3DS emulator running commercial ROMs, while others royal that's already been ported to other programmers have to make a donation of $2.50. The first DeSmuME is printed in French, but had client translations to other languages. The emulator lacks contact-test and sound espousal, but some software exceptions.
