i took a look at the menu overlapping, if you use the JP bin files (rootR/mnu/bin) it will look a LOT better. it will also fix the layout problems in the library/books menu.
i also made a tool to extract all textures from a TXM-TXV pair. this is for those who might want to work with textures too. usually a tex file is a fps4 file, after unpacking it you will get this header-content pair. then you start texpack and tell the TMX (header, smaller file, File00000), TXV (the bigger one, File00001) and the output folder. it will save them as raw file, but a file list with resolution and encoding type is generated.
there are two kinds of encoding i have met, the first is a simple RGBA but i don't know what the other is. it uses 4 bytes too that is sure. also there is no repack function yet, but you have to set the -u parameter.
solus: are there any error messages or something? what do you mean it closes immediately?
I can't open any of the exe's you posted, I open it then it closes less than a sec no error msgs. I tried my other newer laptop as well, maybe it's because I'm using laptops or something.
I always have to use the command prompt then guide it to the directory of the exe so I can open it without it closing, but I fixed the problem where the chestfix.exe couldn't find cpkforp I had to change the path in my computer properties' advance system settings. Now I'm trying out skitfix. The fps4pack is giving me those 4 errors now, I will have to use a different cpu again.
