What about the PSP specifically would be particularly special about it? Not ragging on the thing, I never owned one, but uh yeah, why that?
I like some others probably would be highly interested to see someone try to port this to an actual PS1, playable on one or an emulator. Obviously a lot of the PC-centric stuff like the crapton of graphics options would be gone, would have to be redone a lot from scratch as Unreal Engine 4 is not something a PS1 could handle pretty sure lol, and I don't know what other sacrifices would be made (I am no expert on the console's inner workings and tech) but yeah, I just want to see the true extent to which a real PlayStation could remain faithful to the demake and BB in general's vision.
