Some players are having trouble connecting to TPU when it's running DCFinal maps. There are a bunch of different DC maps and mods out there and it's bit confusing, but as far as I know, it works like this:

DesertCombat is a full modification for BF1942. Its last version was 0.7N. That's the version I'm running on the TPU server and on my client computer. Here are the DC files on Filefront.

DCFinal (aka dcfinal/DC_Final) is apparently a mini-mod for DesertCombat; it requires DesertCombat to work properly. DCFinal's last version was apparently version 3, although that version appears in the BF1942 client as version 0.8, and also as 0.8 in the server browser. I'm running that version on the TPU server as well as on my client computer. Here are the DCFinal files on Filefront.

I've made all the required files available from the Files and links page on this web site, which you can find in the left column.

Note that you will also need the DC versions of the Secret Weapons and Road to Rome maps to play those maps on TPU. They are also available on the Files and links page.

If anyone has any different information about the Desert Combat mods and their most recent versions, please let me know and I'll update things accordingly.
