New to Ds Options

Can someone please forward to a dummy guide of modding the DS.

My kids have two, and I saw the nes & genesis emulators run on youtube.

How do you do this?

How do you run homebrews?

Can you play backups on it?

Thanks in advance.

 

Try reading like... ANY of the guides in the DS section.

Heres a good one to start with http://forums.afterdawn.com/thread_view.cfm/585265

 

thanks
