Key points

Content from this game can be imported into an install of its sequel, Enemy Engaged: Comanche vs Hokum, adding the two helicopters and three scenarios into the sequel's update game engine. This can further be combined with community-made mods (such as those found at EECH allMods) to update the game and add new features and content.

Issues unresolved[edit]

"Unable to create Zbuffer surface: DDERR_NOZBUFFERHW" Error"[edit]

This is likely caused by a PowerVR card in your computer. These cards are not supported and there is currently no fix.

Issues fixed[edit]

Low frame-rate and incorrect resolution[edit]

Use dgVoodoo2[1]
  1. Disable compatibility mode for older versions of Windows (The GOG release has this on for Windows 98 SE by default. Not doing this may result in visual artifacts).
  2. Download dgVoodoo2.
  3. Extract the contents of the .zip file into its own directory on your system, perhaps C:\dgVoodoo2.
  4. Copy the contents of dgVoodoo2\MS\x86\ to <path-to-game>\Aphavoc\. (If anti-virus programs warn about or quarantine the .DLLs, be sure to add them as exceptions to the anti-virus' detection.)
  5. Run dgVoodoo2\dgVoodooCpl.exe.
  6. Add <path-to-game>\Aphavoc\ as a config folder by pressing the "Add" button and browsing to the directory. Ensure that the folder shows up in the list and is selected.
  7. Under the General tab, select "Centered, keep Aspect Ratio" as the scaling mode.
  8. Under the DirectX tab, select "dgVoodoo Virtual 3D Accelerated Card" and set 512 MB as the amount of VRAM.
  9. Under the DirectX tab, set the resolution to a multiple of 640x480, such as 1280x960. While in-game, do not change the resolution from 640x480 using Ctrl+F3/Ctrl F4. Otherwise, the cockpit will remain 640x480 and shrink at higher resolutions as the cockpit bitmap isn't scaled in-game. Setting it back to 640x480 will resolve this.
  10. Start the game and test out a mission.
  11. If it works well and dgVoodoo2 is confirmed to be working, under the DirectX tab, disable "dgVoodoo watermark".
Tested on dgVoodoo 2.78.1

Rainbow coloring[edit]

See the Rainbow color problems in older games page for details on fixing this issue

Problem with Riva128 chipsets[edit]

Riva128 chipsets can cause graphical artifacts, use this fix if you believe you're having graphical artifact problems.
/3dce command line option[citation needed]
  1. Open the command line while in-game
  2. Input /3dce
  3. Play game

Invisible pylons and power lines[edit]

3Dfx chipsets, notably the Voodoo2, cannot render lines in newer versions. Reverting to version 2.5 of your graphics drivers will correct this problem.

Other information[edit]

Console commands[edit]

Parameter Description
/3dce "3D clean edge" - Cleans up the graphical artifact
/3dreset "3D reset" - Sets the default screen resolution to 640x480. This may be required if the game crashed whilst attempting to use an unsupported display resolution.
/cbar:[value] "city block approximation range" - Sets the distance (in meters) at which city buildings approximate. The default value is 500 metres (/cbar:500). On faster PCs you can increase this value to reduce the 'pop-up'effect.
/cg "clean graphics" - Re-installs the graphics files from the CD.
/dcdz:[value] "dynamics cyclic dead zone" - Sets the joystick dead zone as a percentage. The default value is 0 (/dcdz:0).
/ns "no sound" - Disables sound if the program has problems with your sound card.
/cdrs:[value] "comms data record size" - Sets the initial estimate for the maximum size of the campaign data (in bytes). If the value is too low the program will be slower connecting, too large will waste memory. The default value is 200000 (/cdrs:200000).
/cist:[value] "comms initial sleep time" - Sets the length of time (in milliseconds) the program will wait before sending packets. This is to allow DirectPlay to establish a stable connection and may vary with proprietary service providers. The default value is 500 (/cist:500).
/cpt:[value] "comms packet timer" - Sets the length of time (in seconds) the program will wait for a packet before re-requesting it. The default value is 5 seconds (/cpt:5).
/crls:[value] "comms re-send list size" - Sets the number of packets kept in the history buffer. This is required for re-sending lost or corrupt packets. The default value is 1000 (/crls:1000). Increasing this value may improve reliability but requires more memory.
/crl:[value] "comms re-request limit" - Sets the number of times a missing packet will be re-requested. The default value is 10 (/crl:10).
/crto:[value] "comms re-send timeout" - Sets the length of time (in seconds) the program will wait for a re-requested packet before asking for it again. The default value is 1 second (/crto:1). This value may vary with service providers.
/mur:[value] "maximum update rate" - Sets the maximum update rate (in iterations per second) for the communication system. This is independent to the visual frame rate but will never exceed it. This may be used to limit the amount of packets sent and help avoid 'swamping' a connection. The default values vary according to the connection method:

IPX  : 15 (/mur:15)

Serial : 15 (/mur:15)

Modem  : 5 (/mur:5)

TCP/IP : 5 (/mur:5)
