Requirements

  • .NET Framework 4.8 — included in Windows 10 (1903 and later) and Windows 11.
  • No administrator rights needed.

Installation

  1. 1.Back up the original steam_api.dll in your Black Ops folder.
  2. 2.Copy all files from the bgT5 package into the Black Ops folder, next to BlackOps.exe and BlackOpsMP.exe.

The simplest setup is to allow bgT5Launcher.exe and BlackOpsMP.exe when Windows asks.

Known issues

  • Player stats only exist on the PC that hosted. If someone else hosts next time, players start from zero there.
  • Only game builds 7.0.164 (multiplayer) and 7.0.152 (singleplayer) are supported. Other builds start without bgT5’s patches.
  • No automatic host discovery yet — the host IP has to be entered. IPv4 only.
  • With VPNs or overlay networks (e.g. Hamachi) the IP shown in the launcher may be wrong. Enter the host IP by hand. Not tested.
  • v0.7.2: 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 v0.7.2.
  • 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 v0.7.2.
