This "Unlock All Mission" file works exactly as described! I’ve played IGI 1 a dozen times, but I always hated getting stuck on the earlier levels just to reach the fun snowy missions later on. This save file saved me a lot of time. It worked perfectly on my old PC.
If you are a true "Usttad" (master) of the game and just want to have fun, definitely download this. Just a heads up: make sure to back up your original game files before replacing them!

The original Usttad unlocker was a small .exe trainer called IGI_Mission_Unlocker_Usttad.exe (often bundled with “IGI 1 Full Crack Usttad Edition”).

FF 7F 00 00 (binary: 11111111 01111111 – 14 bits set)
Step-by-step for Ustaad:
Risk Warning: One wrong bit and the game crashes on launch. Always export the registry key as backup first.
Right-click IGI.INI → Properties → Check Read-only. This prevents the game from resetting your progress to Mission 1 after you play a later mission. This was the killer feature of the Usttad trainer.
If after following the “unlock all mission in igi 1 game usttad” method you still see only 4 missions:
