NDS Browser rom not working

I put it on my Supercard and nothin'. It fails to load. SuperKey normally works just fine with everything else.

the DS browser will not work unless you have an official ram expansion pack or a slot 2 flashcart to act as a ram expansion.

Try using bunjallo or DSOrganize, they both have good browsers
