Kilroy,
No, I have not officialy released a version of my sound mod for HSFX 6. What you can do though is copy the contents of the UP 3.0 version of my sound mod into the "Files" folder in your HSFX 6 installation. If done correctly, you will have both a "presets" and a "samples" folder within the root level of your "Files" folder (do not copy the entire "9_JTSM_v2.0" folder from the top level).
You will then want to open the ".rc" file also located in the "Files" folder. Use Notepad to open this file. Scroll all the way to the end of the file and insert a "#" character in front of the following lines:
@sfs MOUNT fb_hfxsounds.sfs
@sfs MOUNT fb_hfxsounds01.sfs
So, the lines will look like this:
#@sfs MOUNT fb_hfxsounds.sfs
#@sfs MOUNT fb_hfxsounds01.sfs
Next, using JSGME, you will want to disable "TIGER Flybys" and enable "SOUNDS Default".
Start HSFX 6 and you should be hearing my sound mod in its entirety. One thing I noticed though is that in HSFX 6 my sounds have considerably less volume than they do in UP3 or DBW. I'm not sure exactly why this is but is likely due to the way HSFX 6 is coded.
