Archived build. This is the workbench as it stood before opcode transposing moved onto the per-patch opcode diffs. It only knows the patch tables baked into its own opcodes.js (7.51 and later), and it is not updated. Go to the current version.

Opcode.Inspector

FFXIV .dat packet sniffer

Drop a recording to read every server-zone IPC packet it contains — opcode, size, timing and a raw hex view of the bytes. Built to hunt down the two opcodes the workbench has to hand-enter each patch: PartyList and PartyPortraitInfo. Everything runs in your browser; the file never leaves your machine.
