I've looked this forum over, along with google, a hundred times trying to piece together what little information I could on ripping WindSlayer (a dead 2009 mmo) sprites. Still no luck. The developers have given the data files for the game custom extensions that I'm assuming don't hold much value in terms of decrypting the files. You can easily change the .hsc files to .zip and extract them, but then you don't get anything but a file named "temp_file" with no extension. The other files are .hsi, and .hmi, and you can't extract those. You can open the "temp_file" in TiledGGD, but it won't give you anything but a bunch of pixels. I've tried using the .hsi and .hmi as pallets in all kinds of combinations, but it still won't give me anything other than crazy pixels. There are a few other files named "windslayer" with different extensions like .hbi, .hci, .hii, etc. They won't work as pallets and can't be extracted either. I don't really know what the next move is, does anybody know what to do now?
