ButterStorm Packet question

Hey guys,
I have a quick question about packets in ButterStorm. Now that I have got the server running, I am wanting to learn to code features. In the emulator, it says "Handled / Unhandled Packet" when certain items are clicked in the emulator.
With the Unhandled Packets, are they the CORRECT packets for a certain feature in the client? For example:
When I click 'Games', I get unhandled packet: 1536. Is this the packet I use to code a certain feature to work with the 'Games' area?

If I am incorrect, could you please explain in more information as I am still new to all this?

Thanks :)
