Before anybody chooses to get frustrated and flame me, keep aware that I'm perfectly aware of the engine's inability to sync AI. The context of this post takes external applications into consideration.

Here I go:

I once made an application/program that could limitedly sync AI.

It worked as so:

It was limited to two players. A server and a client. It would read coordinate data (x,y,z,yaw) of the bipeds from HaloCE's process memory, send it over the network, and if the same application was running on the other computer, it would inject those values into the process memory of HaloCE on that computer.

I never finished the application, for one major reason:

I can't seem to find any documentation on how objects in general (vehicles, bipeds, scenery, weapons, etc etc etc) are stored in Halo's memory.

Any chance that a very very very advanced modder could help me, or at least somebody point me to some documentation on HaloCE's memory?

Thanks in advance! :)

See if that helps at all.

OR at least 4 players
because it would be nice to have a coop map to play or a mod or a30 or b40 to play in coop over internet hope it works in the near future
