==How to run 2 ArmA on the same PC==
A fast way to setup MP missions is to run two ArmA games on the same computer. Let's call the first *''Editor'' and the second ''Client''
*''Editor'' run the mission editor, selected clicking on ''Multiplayer -> New -> Edit/New''
*''Client'' can now join it selecting ''Multiplayer -> LAN'' or ''Remote'' wiht IP ''127.0.0.1''
**It will see ''Editor'' in edit mode.
*As ''Editor'' clicks on ''Preview'' to run the mission, a PBO named <tt>__cur_mp.pbo</tt> is create d on the fly for ''Client'' to be downloaded.
*Both now enter the usual lobby and choose the slot they want
*They play the mission, and when they leave back to the lobby, they can choose:
**to run it again
**to go back
***''Editor'', in this case, returns in the the mission editor
***''Client'', in this case, returns to the ''Wait for host'' screen.


In order to avoid to click through the menus, you can choose to start the two ArmA by command line:
For ''Editor''<pre>
\ArmA\arma.exe  -host
</pre>
For ''Client''<pre>
\ArmA\arma.exe -connect=localhost
</pre>
I like to suggest adding<pre>
-window -nosplash -nopause
</pre>to speed up things and run safe from alt-tabbing.
You can start them at the same time, for instance using a .cmd like this:<pre>
start \ArmA\arma.exe -window -nopause -host
start \ArmA\arma.exe -window -nopause -connect=localhost
</pre>
===Problems===
All of this above should works if ArmA doesn't check for duplicated CD keys, and you have a single operative system user and a single installation of ArmA. You maybe know that there is an option in [[server.cfg]] called [[server.cfg#Server_Options|kickduplicate]], which if set to 0 allows the same CD key to join a MP game. The problem is that server.cfg, or better, the file you provide with [[-config]], is only read if you run ArmA with [[ArmA:_Startup_Parameters#Network_Options|-server]] or the dedicated <tt>[[ArmA:_Dedicated_Server|arma_server.exe]]</tt> or <tt>server</tt> on [[ArmA:_Dedicated_Server#Linux_2|Linux]].
Because this check is done online at gamespy, if you drop your internet connection, the check isn't done. But this could be a problem, because while editing or testing, you usually want to search some forums or other online resources.
