Old Engine/Game Protocol
From RuneWiki
I recently rewrote the content here to adopt the official nomenclature as much as possible.
Check out the list for revision 225.
If you see any lowercase or hyphenated names in the un-versioned list, they're from my previous work in 317 and not used in 225.
If you see a packet with an asterisk (*) next to it, it's an unofficial name.

Client to Server Communication
This table is structured from the packet opcode lookup in the client. Sort by ID to see how packets are grouped, they all have reserved areas typically e.g. anticheat packets (randomly added during obfuscation) will exist from 60-75, player options will exist from 100-109, and so on. The "ID" column here is fixed across revisions.
