These display items include your radar, compass, and heat and coolant gauges, as well as other displays with targeting information such as enemy direction, range, and damage assessment. 
C.	DirectX Issues
If you have any video or audio problems, see “Display” or “Audio” in Section E, “Configuration Issues.”  For issues related to your 3D card, see Section F, “3D Card Issues.” For other problems, see the latest DirectX troubleshooting information at http://support.microsoft.com/support/directx/.
D.	Gameplay Issues
The following are the known gameplay issues for MechWarrior 4: Black Knight Multiplayer Demo. 
Limited-lives games allow players to rejoin game after losing all lives: To prevent a player from rejoining a limited-lives game after being kicked out, disable Join in Progress on the server or enact a time limit for joining a game in progress. 
Camera Ship controls: The Camera Ship feature can be selected by all players in the game lobby. It allows players to view any part of the map, from many different angles.
Camera Function	Keyboard or Joystick
Pan up	ALT+W
Pan down	ALT+S
Rotate left	ALT+D
Rotate right	ALT+A
Zoom in	ALT+E
Zoom out	ALT+Q
Elevation	Joystick forward or back
Pivot	Joystick left or right
Zoom in or out	Throttle up or down
ZoneMatch/LAN games list shows wrong game or map type: If the game or map type is changed in a game that appears as both TCP/IP and LAN-GUN, and the games list is updated within 20 seconds of the change, the games list shows the earlier game or map type. Because LAN updates are instantaneous and the query server queries the game server every 20 seconds, wait at least 20 seconds before clicking Update List.
Details option appears to hang: In a LAN or Direct IP game, if you use the Details option in the Server Browser of the multiplayer setup, try to get information on a server, and the host drops out, you receive the following message: “Receiving Player Info...” The message goes away a short time later.
Mission review does not support bots (AI players): When running a mission review after a multiplayer game containing computer AI players, the players do not appear in the replay.
IP address is only used to browse for games: In the Connection Setup wizard, do not use the control in which you can enter an IP address to browse for a game. The IP address is for future support of game browsing services and is presently unavailable.
Custom decals take long time to load via modem: If custom decals are used in games run on modem servers, the mission load time may be extensive. Administrators of modem servers should disable the use of custom decals in the Options screen for a multiplayer game.
Turrets and objective buildings cannot be damaged by ramming with ’Mech: In the game Siege Assault, the ability to damage to turrets and objective buildings by ramming them with ’Mechs has been removed to make these objects more difficult to destroy.
Changing resolution during Setup: If you change the screen resolution while running MechWarrior 4: Black Knight Multiplayer Demo Setup, the installation screen is not fully visible. To avoid this, do not change the screen resolution while Setup installs the game.
Poor performance and instability: If you have direct memory access (DMA) installed on a computer running Windows 98 or Windows Millennium, make sure you have DMA enabled. Enabling DMA will greatly improve performance and stability.
To enable DMA
1.	Close all open applications. 
2.	Click the Start button, point to Settings, and then click Control Panel.
3.	Double-click the System Icon.
4.	Click the Device Manager tab, and then double-click Disk Drives.
5.	Select IDE/Disk (hard drive), and then click Properties. 
6.	Click the Settings tab, and then select the DMA check box.
7.	To restart your machine with DMA enabled, click OK.
Enabling numeric keypad controls: If you want to use keys on the numeric keypad, or num pad, for control, press the NUM LOCK key.
Disabling the mouse Y axis: If you want to use the mouse to steer the ’Mech, you must add the following line in the [Special Commands] section of the Optionsx.ini file to disable the Y axis on the mouse.
mousey=[true, false] 
True is the default, and false means to ignore the mouse Y value. You can find the Optionsx.ini file in the folder where MechWarrior 4: Black Knight Instant Action Demo is installed. 
Mapping mouse buttons to controls: You can map the mouse buttons to controls, but you must first assign each button to a key with the mouse software. For example, button 4 would be the K key, so that when you press button 4 you are remapping K to whatever control you want. Mapping works only for mouse buttons 4 and up.
Optionsx.ini error message: If you start the demo and receive the error message “optionsx.ini is a required page!” you might have accidentally deleted your Optionsx.ini file or reinstalled the demo to a new directory. To fix this problem, in the folder where the demo is installed double-click Autoconfigx.exe. Doing so creates an Optionsx.ini file for you, and you can then successfully start the demo.
HUD font seems too large: By default, the text fonts in the HUD are set to be large and legible, but this setting can cause them to bleed past the margins in some screen resolutions. To make your font size smaller, in the folder where the demo is installed double-click Autoconfigx.exe. Then click Advanced, select HUD Font Size, and then select a smaller size from the list.
Fonts are hard to read when graphic detail is set to low: If your computer is running Windows 98 or Windows Millennium and defaults to 640 x 480 screen resolution, change your resolution in the demo to 800 x 600 to be able to read fonts properly.
E.	Configuration Issues

The following information will help you configure your server in order to use the ZoneMatch feature that MechWarrior 4: Black Knight Multiplayer Demo provides. 
Internet Play
•	The TCP/IP protocol for LAN and Dialup Networking must be installed in order to browse for games.
•	Firewall users must open up ports to use ZoneMatch and DirectX 8.0 DirectPlay port ranges to successfully participate in games. Matchmaking needs the following TCP ports opened: 27999, 28805, 28806, 28807, 28808. For pings to work properly, UDP port 28800 must be opened. Check http://support.microsoft.com/support/kb/articles/Q240/4/29.asp for ports needed for playing DirectX-based games.
Internet Network Connectivity
This section describes the network configuration required to play MechWarrior 4: Black Knight Multiplayer Demo games with other players through a firewall, proxy server, Network Address Translation (NAT), or Internet Connection Sharing (ICS). This section does not apply if you are playing standalone or on a LAN.
If you are unable to find or advertise a MechWarrior 4: Black Knight Multiplayer Demo game on the Internet, then check with your network administrator, who must configure the firewall or proxy server to allow the games to pass information through the proxy server or firewall. 
The following TCP ports must be open: 27999, 28805, 28806, 28807, 28808
The following UDP port must be open: 28800
To verify that these ports are open, contact your network administrator or Internet service provider (ISP). If you are the administrator of the network, consult the documentation for your network software for information about how to open these ports.
For additional information about how to configure a network firewall or proxy server to play a DirectX-based game on the Internet check out the article at http://support.microsoft.com/support/kb/articles/Q240/4/29.asp from the Microsoft Knowledge Base: Q240429 DirectX: Ports Required to Play on a Network.

Unfortunately, some firewall solutions, including Microsoft Proxy Server 2.0, won't recognize additional inbound connections as subsequent connections. The workaround for this is that each port in the range 2300, 2301, 2302, and so on, must get its own protocol definition, as if it were an application-specified fixed port. Practically, only as many ports as active DirectPlay applications need to be opened, that is, to run both the applications "SuperDuperGame" and "WackyFunGame" at the same time, only ports 2300 and 2301 will be used.
ICS Configuration
This is what will and won't work with MechWarrior 4: Black Knight Multiplayer Demo regarding ICS/NAT support in different operating systems.
If your router machine (the one actually connected to the Internet) is running:
Windows 98 Standard Edition: Does not support the DirectPlay protocol, this means that MechWarrior 4: Black Knight Multiplayer Demo will not work at all (hosting or client) behind this type of ICS machine.
Windows 2000: Supports the DirectPlay protocol which means it will work. You are able to host behind the ICS as well as have multiple-client capability.
Windows Millennium: Supports the DirectPlay protocol and has RSIP/PAST support. If all the clients behind this ICS are Windows Millennium or have DirectX 8.0 installed, they will be able to have multiple clients at the same time and also have the ability to host without a problem.
Windows 2000 and Windows Millennium should install the file Ics.inf and then restart the computer to support ZoneMatch. You must have ICS installed first.
