It really doesn't need a remake, it just needs a port to modern systems, upscaled textures, and bumped up to 60fps. It doesn't need anything else, and it's weird that Fromsoft hasn't bothered to do any of that.
It makes sense that they wouldn't want Bluepoint to do a full remake too because they took a lot of weird liberties in Demon's Souls IMO. They're 10/10 technically but they changed things that didn't need to be changed and refused to touch things that everybody wanted changed (why is the gargoyle's AI still broken...)
I'm totally keeping my eye on the emulator, but from what I heard it still needs more time. I've heard of occasional crashes, vertex explosions, random graphical issues happening. Also, it needs a really good computer to run at 60fps.
I'm excited for when it does work flawlessly, but I do wish they'd just port a native version to PC.
