The settings are as follows:

In the [Sim Controls] section of JF4.INI, the "throttleAxis" setting controls how the simulator will access the throttle:
- throttleAxis == 0 Automatically detect the correct axis. Should work with 99% of all throttles.
- throttleAxis == 1 Use the "lZ" value, this will support "old style" sticks and throttles.
- throttleAxis == 2 Use the rglSlider[0] value. This will support "new style" sticks and throttles.
• Stuttering Sounds When Launched from AutoPlay - On some systems, the sound would stutter and sound garbled when the game was launched from the autoplay application on the CD. When running via the start menu, sounds were OK.
We believe DirectSound does not initialize properly on some machines when the CD-ROM drive is the "current directory." The AutoPlay program has been modified to set the current directory to where JetFighter IV is installed. Current users should simply launch JetFighter IV from the Start Menu to avoid this problem.
