 In the 4.7 version of UnknownAnimeGamePS Grasscutter fork, I've added an option called "useXorEncryption" in config.json, which is disabled by default. If the option is enabled, you won't be able to enter the game using the patch provided above, you will have to use a patch which patches the client's RSA key.
