COMMANDOS.EXE:
In 2020, Kalypso Media released Commandos 2 - HD Remaster and, importantly, the Commandos Classics Collection. However, note: Behind Enemy Lines was remastered under Pyro Studios' "Commandos: Behind Enemy Lines – HD" (Available on Steam).
The most frequent hurdle is the "DirectX 5" error. Windows 10 often fails to recognize the original executable's name as a valid application.
Difficulty (89%): It is notoriously punishing. Even losing one commando often means game over, making frequent saving and loading essential.
Windows 10 Compatability Mode Settings - ACTUAL :: Commandos
Modern Windows versions cannot find the legacy DirectX 5 files the game expects. Locate Game Folder: Right-click the game in or GOG and select Browse Local Files Rename the Executable: Find the file comandos.exe . Rename it to commandos.exe (add one 'm'). Enable Legacy Components: Start Menu Turn Windows features on or off Legacy Components , expand it, and check DirectPlay to install. ⚙️ Step 2: Compatibility Settings
Even after these steps, the game may launch in a tiny window. This is historically accurate but not ideal. To achieve fullscreen without distortion, you have two choices. The first is to use Alt+Enter after the game launches, though this may stretch the image. The second (and better) approach is to edit the COMMANDOS.CFG file (created after first run) or use the GOG/Steam launcher to set a scaling option. For NVIDIA or AMD graphics cards, force GPU scaling with "aspect ratio" preservation in the control panel. This will add black bars on the sides but keep the commandos from looking like squat, warped dwarves.
