I'm surprised nothing about this game has turned up already. Either that or I'm not looking in the right place. Either way, the organization of the game's files are ridiculously simple, the files themselves however, are not as simple as one would hope. They appear to be similar to the standard 'bfres' models frequently used in Wii-U games, having the extension ".sbfres", but at first glance I'm going out on a limb to say they are compressed in some way, judging by the file size. I was hoping someone would be willing to look into them and help figure out a way to extract the models and textures properly. Here's a sample of an NPC model and it's accompanying textures, specifically for Prince Sidon.
