Remember to put the three exe of ASTC in the BAT in the same directory in the same directory.
I've done about 16 images in total, but the process for this is actually quite tedious. Now that we understand how to decrypt them, I have to imagine there is a script or tool that can be made at some point to automate the entire process, from decrypting the image header to converting the astc files to png format. I understand bihaiorg has a tool but there's been no response from him in regards to any updates, even after DM'ing and email. There are 7,646 image files in total, mostly PNG files and some JPG.
