A rubberized battery cover would be nice, what would be nicer though, is like a soft vinyl mesh, to allow breathability of the palms. Not sure about you guys, but during a boss battle in ANY GAME, my hands turn into flippin' niagra falls.
Also a gripped stylus would be nice for DS. Anyone know of any third-party styluses that fit in the original DS (can be longer) with grip? thnx, it'd maked EBA easier.
