Hi, I'm trying to modify the script of this game (to e.g. make a menu patch). I've decrypted the ROM using rxTools on a 4.5 3DS. I have the ExtractedBanner, ExtractedExeFS, and ExtractedRomFS folders, as well as the DecryptedExeFS.bin, DecryptedExHeader.bin, and DecryptedRomFS.bin files. Inside the ExtractedRomFS folder there is a script folder that looks like what I need. However, the files inside the folder have the .rtz extension. I've never seen the .rtz extension before, and a Google search didn't lead to any results. Furthermore, I've found ctpk files that I know is a 3DS recognised file format. I've tried using https://gbatemp.net/threads/release-ctpk-tool.379796/ to open them, but I get errors that they're not a valid CTPK file. When I open them in a hex editor (I used HxD), I don't see the CTPK header either. Are all the files somehow still encrypted or compressed? How do I tell? Thanks very much for any help! I'm really new to this.
