0x7D is also send if a ladder char tries to join a non ladder game.

The shown error is decided in the client (either for ladder or non ladder)

      case 0x7d:
        if (D2IniData_multiplayer->isLadder == '\0') {
                // Unable to enter game. A Ladder character cannot join a game created by a
                // Non-Ladder character.
          uVar12 = 0x2ab2;
        }
        else {
                // Unable to enter game. A Non-Ladder character cannot join a game created by a
                // Ladder character.
          uVar12 = 0x2ab1;
        }
