Halo Maps

I came upon (mysteriously) a perfect copy of HaloPC, that runs fine, however, it doesn't have all of the map files.

I was wondering if anyone has these missing map files, so i could play all of the multiplayer levels. if you help me find the map files, i will give you my version of haloPC(via PM, of course).
(it can run off a flash drive, so you can play it at school and stuff.)

a list of the missing maps are here:
battle creek
timberland
damnation
wizard
death island

thanks in advance.
