RS2 Client Hacking Question

Does anyone know any tutorials about this? I found a lot but most of them are outdated. Looking through the source it appears that rs does not use the loader.jar anymore.

Anyways i could only find the game jar at world78.runescape.com/gamepackO26tYGteVzeCXJxwEmZq4hI8WPXDCYBP_9332556.jar

 

Yes loader.jar and runescape.jar no longer exist, after the bot nuke update they included it all in one gamepack(md5 hash maybe).jar try asking over at rs-hacking.com
