Capabilities

LAN multiplayerDedicated serverCombat TrainingPlayer stats
  • Dedicated server: Runs a server without playing on it. From v0.9.0 with game modes, map selection and bots, set up in the launcher.
  • Combat Training: Against bots, with Hostmode on your own PC. From v0.9.0, bots also play on a dedicated server.
  • Player stats: Stored on the hosting PC. From v0.9.0 also in your own profile, so they follow you to any host.

Not yet verified

Present in the code, but not yet confirmed in actual play.

  • Zombies — Lobbies register; a full LAN match has not been tested.
  • Campaign — The singleplayer executable is patched; not tested end to end.
  • Wager matches — Handled by the server code; not tested.

Releases

v0.9.0In preparation

Not released yet. Planned changes:

  • New launcher interface.
  • PlayerID and nickname stored on your own PC, with import of an existing player.
  • Your stats travel with you: stats, classes and playercard are kept in your profile and synced with whoever hosts. The host needs v0.9.0 too. Not tested yet.
  • Find hosts on your network with one click, or host on this PC if there is none. Not tested yet.
  • Choose the network you play on (LAN, Wi-Fi, VPN, Hamachi…). Not tested yet.
  • The launcher finds Black Ops and installs, updates or removes bgT5 in the game folder. The original steam_api.dll is kept. Not tested yet.
  • Dedicated server set up in the launcher: name, game mode, Hardcore, players, password, maps and bots. The server starts its first map by itself and can be joined right away.
  • Dedicated server fixes: starting the map rotation at launch works, and a script error (for example in the bot scripts) no longer ends the match for everyone.
  • No administrator rights needed for playing, Hostmode or the dedicated server. Only installing bgT5 into a game folder under "Program Files" asks once.
  • The launcher checks the host before starting.
  • A second player with the same PlayerID is refused, with an explanation.
  • Log files for the LAN service and the server.
  • Built on .NET Framework 4.8.
  • Many robustness fixes.

LAN setup for v0.9.0

Preview

For the upcoming release. These steps don’t apply to v0.7.0 and may change before v0.9.0 is published.

Show v0.9.0 requirements and instructions
The bgT5 0.9.0 launcher: player card with nickname and PlayerID, network card with Host, Find and Your IP, the Hostmode switch, and tiles for Multiplayer, Campaign & Zombies and Server.

Requirements

  • Windows. All components are 32-bit and run on 64-bit Windows.
  • Call of Duty: Black Ops, multiplayer build 7.0.164 and singleplayer build 7.0.152 (the current Steam builds).
  • .NET Framework 4.8 — included in Windows 10 (1903 and later) and Windows 11.
  • No administrator rights needed. Installing bgT5 into a game folder under "Program Files" asks for them once.

Installation

  1. 1.Extract the bgT5 package to any folder, for example Documents.
  2. 2.Start bgT5Launcher.exe. It finds Black Ops; if not, choose the game folder.
  3. 3.Click Install when the launcher offers it. It copies bgT5 into the game folder and keeps the original steam_api.dll as a backup.

Remove bgT5 restores the original files. Install, Update and Remove bgT5 are behind the game status at the top right of the launcher. Copying the package into the game folder by hand, as with v0.7.0, still works.

Host a game

  1. 1.Switch on Hostmode.
  2. 2.Allow network access if Windows asks.
  3. 3.If you have more than one network (Wi-Fi, VPN, Hamachi), click Your IP and choose the one you play on.
  4. 4.Start Multiplayer.

The other players find you with Find. You can also send them your IP; Your IP has a Copy button.

Join a game

  1. 1.Click Find and choose the host, or enter the host’s IP address under Host.
  2. 2.Wait for "LAN service answers".
  3. 3.Click Multiplayer.

Dedicated server

The dedicated server dialog of bgT5 0.9.0: server name, game mode, Hardcore, max players, bots with difficulty, port, password and a map selection with shuffle.
  1. 1.Click Server, next to Multiplayer.
  2. 2.Choose a server name, game mode, maps and, if you like, bots.
  3. 3.Click Start server. The server loads its first map; players join it from Multiplayer.
  • If Hostmode isn’t running, the dialog offers to start it too: the server logs in to the LAN service like a player.
  • The server uses the network chosen under Your IP.
  • Use my own server.cfg starts the server with main\server.cfg from the game folder instead, and warns about common mistakes in it.

If Windows asks, allow bgT5Launcher.exe and BlackOpsMP.exe. A firewall rule made by hand needs all of these ports.

Known issues

  • v0.7.0: player stats only exist on the PC that hosted. If someone else hosts next time, players start from zero there. v0.9.0 syncs them with the player’s profile.
  • Only game builds 7.0.164 (multiplayer) and 7.0.152 (singleplayer) are supported. Other builds start without bgT5’s patches.
  • IPv4 only.
  • v0.7.0: no automatic host discovery; the host IP has to be entered. v0.9.0 has Find. Its broadcast doesn’t cross routers and some VPNs drop it; entering the host IP always works.
  • v0.7.0: with VPNs or overlay networks (e.g. Hamachi) the IP shown may be wrong; enter the host IP by hand. v0.9.0 lets you choose the network. Not tested.
  • v0.9.0: don’t run the launcher as administrator; it isn’t needed. If you sometimes do, Windows keeps two separate copies of the game’s settings and logs, and the game seems to forget settings. Stats aren’t affected.
  • v0.9.0: Windows 7 needs .NET Framework 4.8 installed separately, and the launcher shows no icons there. Not tested.
  • On a second monitor with different display scaling, the launcher may look blurry.
  • v0.7.0: two players with the same PlayerID broke matchmaking. Fixed in v0.9.0.
  • v0.7.0: installed under "Program Files" without administrator rights, settings were not saved and a new PlayerID could be created on every start. Fixed in v0.9.0.
