I am playing around with compressed images with Etrian Odyssey. I am not really too experienced so I don't understand this compression. I know it is LZ77 but its of type 30? I know that the first two hexadecimals are suppose to determine the type. The other images in the game are type 10 but the battle character portraits are 30. I was wondering how I can compress the decompressed images back to type 30?
