Update 3

Update 3 fixes a number of problems users have found, particularly 
hardware compatibility issues.  Force Feedback joystick support is 
also included in this update.

Windows 2000 Keyboard Problem
Keyboard response in the simulator on Windows 2000 was sometimes 
over 1 minute delayed! This problem has been fixed for Windows 2000 
users.

Main Menu Background Garbled on ATI Graphics Hardware
Main menu background looked 'crazy' on some ATI graphics hardware.  
For some reason, certain ATI graphics hardware, particularly that 
found in laptops, use a ARGB_1555 framebuffer instead of the much 
more common (and better looking) RGB_565.  This problem should be 
corrected for all such hardware.

HUD Text Solid Blocks on ATI Hardware
On some ATI boards, the text in the simulator shows up as solid 
blocks.  This problem should be solved for all ATI hardware.  Please 
send us an email if your HUD text still shows up as solid blocks.

Force Feedback
The new simulator will detect and use a force feedback joystick if 
one is available.

USB Throttle Support
Some USB throttles were not being used properly in the simulator.

Newer throttles changed the 'axis' that data is available from.   
The version attempts to determine the correct axis automatically.  
If this does not work, there is a setting available in JF4.INI to 
override the default behavior of the throttle.  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.
