Yep. Gotta use your firmware. Most of the ports are crap and never get updated anyways. http://www.linfoxdomain.com/nintendo/ds/
its probably because your using wood r4 for r4 originals, on a clone, which the saving doesnt work, what cart do you have, and what wood r4 are you using, just use ysmenu if your cart is a clone, has better compatibility than woodr4 for clones,
