Looks really good! Only things I find missing are XYZ support and RTP name translation. Both could be copied over from Player. For example the XYZ image loading code could be put into LoadImage() or sdl_image could be replaced completely. Thinking this further, we could even factor out the image loading/saving code from Player into a separate lib and use this in both... RTP table is another story and IMO not worth currently.

Thank you for improving lmu2png!
