It's simple enough to do, and has been asked on this and other boards many a time.
All you need to do is copy the mirc.ini file from the location that it was put in (you can get this by typing //echo -a $mircdir in any open mIRC window), then copy it to your bot's directory (which will have a copy of mirc.exe in it)
Then when you run the mirc.exe from your bot's folder, it will use the mirc.ini file from that same location.
