just go to console.cpp and at the top under Code: 
OgcConsole gConsole 


add Code: 
void DrawHudString (int x, int y, int r, int g, int b, const char *fmt, ... ); 
void tintArea(int x,int y,int w,int h, struct ColorEntry* clr); 


and find 

Code: 
void OgcConsole::draw(int con_x, int con_y, int con_w, int con_h) 


and replace this with the code 

Code: 
void OgcConsole::draw(int con_x, int con_y, int con_w, int con_h) 
{ 
   if(!active && !curHeight ) return; 
   int nscroll = scrollEventCounter.get();
