found a ghetto way, it takes a few seconds to update the loading screen :

in game_local.h

class idGameLocal : public idGame {
public:

idUserInterface * mploadingHud;; //add this

}

in game_local.cpp
/*
===========
idGameLocal::Clear
============
*/
void idGameLocal::Clear( void ) {

mploadingHud = NULL; //add this

}

/*
===================
idGameLocal::InitFromNewMap
===================
*/
void idGameLocal::InitFromNewMap(
........
SetGameType();

//add this ->
mploadingHud = uiManager->FindGui( "guis/loading/mplevel.gui", true, false, true );

if ( gameLocal.IsLMSGameType() && mploadingHud ) {

mploadingHud->SetStateString( "server_limit", va( "respawns %d", si_lmsRespawns.GetInteger() ) );
SetupLoadingGui( mploadingHud );

}
//<- add this

LoadMap( mapName, randseed );
..........
}

infinate gametypes can be added without the engine source

n1 :)

hint : you can use handlenamedevent( "showServer_info" )
