Sorry if this isn't the right place to post this, i tried to narrow it down as there is no section dedicated to the game Latale.
Some people may find this tool useful, it sniffs and decrypts Latale packets through the ports of 10000~10008 (Can be easily modified through decompiling and recompiling with a .net decompiler)This works for both Sending and Receiving.
This tool is essential if one was to ever attempt creating a private server.
