VF5FS Judgment and Yakuza versions??

It seems like its always the same route in that is presented in arcade mode. Is this true? Is there some way to change routes? Is there anyway put the difficulty on hard? I couldn't find it right off.

General Question: about VF5FS in Judgment and Yakuza 6. Since this amount of VF5FS has already been ported to this gen console. PS3 Cell port probably being the most difficult. Why not port the whole game and put it on the PSN store?

Does anybody know if this would be impractical for some reason? Hell once they've gone this far, why not port the rest
