XXL Packets Mod is a fork of XL Packets Mod which raises the packet size limit from 2MB to the Java Integer limit (2.147483647 GB). It fixes bug MC-185901 (Impossible to join a server with too many recipes) by raising the packet size limit from 2MB to 2.14GB (2147483647), so that servers with large datapacks, packets, etc don’t kick the client. This mod is needed clientside for any connecting clients.
