Updated the picture text to be less messy for anyone interested. Also considering making an attempt at cleaning up the MTL. If I do, it will still be MTL and I can make no guarantees to accuracy. But if there's interest I'm considering just working through the raws and MTL to try and make it into something coherent and understandable for the most part since I'm doubtful this is going to be getting a proper translation anytime soon. (Though if there is someone working on a proper translation, please feel free to make use of these images and hopefully that will save you some of the more annoying work done.)
