High Quality Content by WIKIPEDIA articles! The Nintendo DS Browser is a version of the Opera web browser for use on the Nintendo DS, developed by Opera Software and Nintendo. The Nintendo DS Browser comes in separate versions for the Nintendo DS and the Nintendo DS Lite; this is due to differing physical size requirements for the memory expansion cartridge included with the browser. The Nintendo DSi is incompatible with the Nintendo DS Browser, though a DSi compatible version of Opera 9.5, Nintendo DSi Browser, is available free from the DSi Shop.
