Svensson reported that the original game assets given to them from Capcom Japan were incomplete, and even after requesting old hard drives and computers to recover more assets, Ready at Dawn was still required to recreate some from scratch. Furthermore, the game had to be recoded to change optimizations that were made for the PlayStation 2 version; Svensson stated that "part of the reason we didn't show it until we started showing it was because, if we showed it in a form that was anything less than near-perfect, people were going to freak out". Ready at Dawn's creative director Ru Weerasuriya later reflected that porting "Ōkami" to the Wii was a challenging task—"we started with no assets and literally reverse-engineered the whole thing back onto the Wii"—they did out of love for the game, but the level of effort would preclude them from attempting such a port again.
