I had to format my hard drive and reinstalled the original Unreal Tournament 2004. When I log in to miasma.rocks my name does not appear. I just changed my avatar, but I used the correct name and password that I've used for years and I don't know what's going on, but my name shows up as Player (MX).
Did you use the set username command, or change the name in the Player category in game settings?
I just changed the name in the player category in the game settings. I don't know the use of any commands ???. It is a version that I have installed several times, maybe the license has already expired and I need to buy a new CD of Unreal Tournament 2004.
UT2004 is not bound to one player name, you can use whatever you like
