Requires Python 2.7. I don't know if it'll work for any of the other files but it works for this particular one.
Here's the code:
https://gist.github.com/polaris-/516218c68c4cd4974e10
Download this EXE and put it in the same folder with the .py file when you run it:
https://github.com/polaris-/ctpktool/releases/download/v1.1/ctpktool.zip
To use it, type "python tex2ctpk.py (filename).bin" such as "python tex2ctpk.py ui_guild_01_ID.bin".
Just a small note: Change the filename to something with an extension, like ui_guild_01_ID.bin or anything. That way ctpktool can create the folder without erroring because the name is already taken by the file.
Edit: Just for anyone who might read this in the future. It generates a (probably slightly invalid) CTPK file out of the image data so my other program, ctpktool, can do the heavy lifting like decompressing the image data and saving it to PNG.
