Nintendo have made sure that no third-party company can develop their own sound engines for the Nintendo DS, a big change from the Game Boy Advance.

Nintendo have made sure that "the ARM7 has been excluded from direct access for commercial reasons.". The ARM7 handles the Wi-Fi, audio and the touch screen. So this means that developers can not create their own sound engines or do work for other developers, which was common on the Game Boy Advance.

With Nintendo preventing this the only way that it may be possible to create sound engines for the Nintendo DS would be to use a lot of coding and investigating into the setup, something most musicians won't know about.

The majority of American and European develops have become very angry with Nintendo stopping them create their own "music replayer, sound effects mixer [or] a decent music GUI for musicians."

This puts third-party games at a serious disadvantage with Nintendo themselves and means there will be less resources. As well as this freelance musicians will not be able to offer their services to third-party developers.

Some developers believe Nintendo may change their mind on this, with one stating "I have hopes they will change it... they say they take our feedback into consideration."
