Finally, all my copies of Angel Beats arrived!
The key that I originally had (0x5F,0x07,0x8A,0x2A,0x66,0xA7,0x11,0xA6,0x84,0x6D,0x9D,0x46,0x9F,0x7A,0xB9,0x7E) is the correct key for the retail version - at least with the sofmap one that I’ve opened up (haven’t opened up the ones that I got from Getchu and Melon books, but I’m willing to bet that there’s no differences and that they all should have the same key). @Hakuryuu, I don’t know where Kelebek got his key from, but after he posted his message I took him on his word and swapped out my original key with his. I’ve since then reupdated the link to the tools with my original key so if you go back to the link and download the tools again it should work.
