18.Nov.1990 From: Jim McConkey, Sr. Sound Engineer, MPS Labs, MicroProse Software The files JSOUND.F19 and JSOUND.F15 are updated and improved AdLib drivers for F19 Stealth Fighter and F15 Strike Eagle II. Due to popular demand, the jet engine noise was made louder in both versions. Both also now detect and compensate for 70 Hz VGA graphics which had previously caused the opening music to be hyperactively fast. Our latest AdLib speech technology was also retrofitted to the F15 driver, providing cleaner speech. To use these files, you have two options. First, you can copy JSOUND.F1? to ASOUND.EXE in your game directory, replacing the previously supplied driver. You should probably rename your old driver first. The second option is to copy JSOUND.F1? to JSOUND.EXE in your game directory and run the game with the command line option: F15 /aJ or F19 /aJ.
