Greetings.
I came across this improved engine (ioquake3) a few weeks back and I must say that I find it very impressive.
But now I am trying to set up a Local server.
I'm using the excessive plus mod though. But I am unable to exec my config for the server.
I will mention how I configured it first.
With the excessive plus mod, there were a few executables provided to place them in the ioquake3 root folder; which I did.
I will be running a dedicated server so here is what I did:
I edited the "xp_dedicated.bat" (provided by Excessive Plus) and changed it to =

@echo off
 
start ioq3ded.x86.exe +set fs_game excessiveplus +set vm_game 0 +set dedicated 2 +exec server.cfg

// misc
 set rconpassword "commander"
 set sv_hostname "Wing*Admiral's Arena"
 set sv_maxclients "10"
 set sv_maxrate "8000"
 set g_gametype "0"
 set bot_minplayers "5"
 
 set fraglimit "50"
 set timelimit "10"
 set capturelimit "6"
 set roundlimit "10"
 
// configuration engine
 set xp_config "rr"   // <---<strong>Config of map placed in \ioquake3\excessiveplus\conf\rr.cfg</strong>"
 
// map rotation (see rotation.txt)
 set xp_rotation "rotation.txt"
 
//  this is needed to start the rotation
//  test_bigbox is good because it tiny
 map test_bigbox

I have also placed the rr.cfg in "C:\Documents and Settings\<Username>Application Data\Quake3\excessiveplus" because it reads the configs from there itself.

So now, after doing all this, I execute the "xp_dedicated.bat" file and my server is up and running.
After logging in to the game, I do not see any difference. It did not load up the map config (rr.cfg).
So I type these commands in console:-

rconPassword commander
rcon exec rr.cfg  (It succeeds in executing)
rcon map_restart
rcon map q3dm17
