Issues fixed[edit]

Misaligned crosshair[edit]

The crosshair on higher resolutions gets misaligned. Top image is at 640x480 (correct position), while the bottom image is at 1280x960 (misaligned).
The crosshair on higher resolutions gets misaligned. Top image is at 640x480 (correct position), while the bottom image is at 1280x960 (misaligned).
On higher resolutions, the crosshair is misaligned with the correct position, preventing accurate aiming. This bug can also break the missile lock-on ability.
Peixoto's patch can force the game to run at the highest resolution available (but preserving the 4:3 aspect ratio) and the crosshair will be in the right place.
Start the game with Peixoto's patch[citation needed]

Window border visible in fullscreen mode[edit]

Start the game with Peixoto's patch[citation needed]

Gamma not working in Direct3D mode[edit]

Start the game with Peixoto's patch[citation needed]
Close other applications[citation needed]
  • Close any gamma-altering applications such as f.lux.

Low frame rate on Windows 8[edit]

Frame rate only reaches ~30 FPS on Windows 8 in Direct3D mode.
Fix frame rate issues[citation needed]

Game crashes on Alt+Tab[edit]

  1. Install Direct3D Patch.
  2. Set Video Mode to Primary.

Cannot change resolution in-game (with nGlide)[edit]

It is recommended to set the internal resolution to 640x480 to avoid the misaligned crosshair bug
Modify the internal and wrapper resolutions externally[citation needed]
  1. Go to <path-to-game>.
  2. Open szHardware.ini.
  3. Change the values of Width and Hight to the desired resolution width and height respectively.
  4. Save the file.
  5. Open the nGlide options menu and set the Screen resolution setting to "By desktop" (recommended).
  6. In-game, go to the Video settings menu and click "Apply Settings" to fix any fullscreen issues.

Notes

  1. SafeDisc retail DRM does not work on Windows 10[1] and is disabled by default on Windows Vista, Windows 7, Windows 8, and Windows 8.1 when the KB3086255 update is installed.[2]
  2. 2.0 2.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/328470/ in addition to or instead of this directory. The app ID (328470) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
