It may not be a rare occurrence these days, but a recent rating reveals that an iPhone title is heading over to DSiWare in the near future.
Action RPG Zenonia, a blend between Legend of Zelda and Secret of Mana, is a pretty decent romp that features the classic elements of swords, oddly-named characters and evil slimes. Oh and there's some scantily glad women and huge dragons in there as well.
Zenonia may have just appeared on your radar but this trailer (featuring the iPhone version) might convince you to put it on your watchlist long term. We'll bring you more details and screenshots as soon as we have them.
