Hello. I'm translating UI of game. but, I was faced with failure. https://github.com/Inori/FuckGalEngine/tree/master/AdvHD this is Willplus Engine Unpacking tools. I trying translated UI image( .png files) to .pna files. Maybe it works well. but, output image is invisible in game. I guess a problem with _cht.bin. It is contained all .pna files. I've attached a _cht.bin. help the analysis. _cht.bin sorry for my poor english, thank you for reading.
