Okamiden: a work-in-progress Nintendo DS matching decompilation

Okamiden is being reconstructed as C source for the USA Nintendo DS release, with compiled ARM9 code compared against the original. The project uses ds-decomp, Metrowerks CodeWarrior ARM and objdiff; the author reports three matched ARM9 source units and keeps nonmatching reconstructions separate. Work is at an early stage.
