This is a patch for version 1.0.2C (UK) of Enemy Engaged by Empire.
It disables the CD check the game performs when you first run it.
All it does is change the data at offset 008C378 from 75 (jne)
to 74 (je).
To run the patch, just copy it into the "Cohokum" folder and make sure the file cohokum.exe is not read-only.
It's probably a good idea to disable the music (which is on the CD) under Options-Sound as well, coz the program might try to play it otherwise.
