Where to find your FS9.CFG

[ardypilot]

You may have wanted to edit you're FS9.CFG but cannot find it.

If this is the case, this information will help you.

It is located at:

C:(or whatever drive your operating system is on)\Documents and Settings\<username>\Application Data\Microsoft\FS9\FS9.CFG

*Note: you will have to make display hidden files and folders to view this file. You can do this by clicking on the "Tools" menu on the main menu at the top of any window, then on the "Folder Options" submenu. Click on the "View" tab, and then tick the appropriate "Hidden Files and Folders" radio button.

Alternatively, click "Start"Â￾ and go to the Run function, then type %appdata%\Microsoft\FS9

Be sure to create a backup copy of your FS9.CFG every time you make a change to it just in case it all goes wrong!

If you wish to create a completely new FS9 cfg, then hold the CTRL and SHIFT keys while FS2004 is loading or simply delete your current cfg from the directory listed above, and FS2004 will automatically build a new one.

howdy,

as different mesh resolutions require a different TERRAIN_MAX_VERTEX_LEVEL= number, it can be a real pain to be continually editing your existing FS9.cfg file. a helpful trick is to create a simple .bat file to switch between TERRAIN_MAX_VERTEX_LEVEL values of 19, 20, and 21.

1. in your FS9 folder located at C:(or whatever drive your operating system is on)\Documents and Settings\<username>\Application Data\Microsoft\FS9\
create 3 folders and name them fs19, fs20, and fs21.

2. copy the fs9.cfg file to each folder.

3. open the folder fs20 and, in notepad, edit the TERRAIN_MAX_VERTEX_LEVEL value to =20.

4. do the same in the fs21 folder, making the value =21.

5. now, create a 'master' .bat file by opening a new txt file in notepad. cut and paste the following text:

C:
cd \"documents and settings"\"owner"\"application data"\"microsoft"\fs9\fs19
copy "fs9.cfg" c:\"documents and settings"\"owner"\"application data"\"microsoft"\fs9
pause
c:

(NB: use the same value \Documents and Settings\<username>\Application Data\Microsoft\FS9\ cited in step 1, above)

6. Save As FS19.bat

viola! you have just created a .bat file.

7. make two copies of the fs19.bat and rename them fs20 and fs21

8. single right click fs20.bat and go to Edit.

9. change the 2nd line: cd \"documents and settings"\"owner"\"application data"\"microsoft"\fs9\fs19

to now read

cd \"documents and settings"\"owner"\"application data"\"microsoft"\fs9\fs20

10. save.

11. single right click fs21.bat and go to Edit.

12. change the 2nd line: cd \"documents and settings"\"owner"\"application data"\"microsoft"\fs9\fs19

to read

cd \"documents and settings"\"owner"\"application data"\"microsoft"\fs9\fs21

13. save.

14. double click the particular .bat file you need and it will now automatically swap over the corrected .cfg file.

if you are not overly familiar with batch files and have concerns with this proceedure, do NOT attempt the above.

Ah ha, clever idea!

I would have never thought to do that, thanks for sharing!

Just a passing thought here:
If you are flying in a part of the world with a less dense mesh, and your fs9.cfg says TERRAIN_MAX_VERTEX_LEVEL =20, what would be the effect?
EDIT after Dorian's reply:
Mmm that may explain some strange effects observed here and there - I always have it set at 19, and never really thought about it much.
Thanks Dorian.

howdy charl,

If you are flying in a part of the world with a less dense mesh, and your fs9.cfg says TERRAIN_MAX_VERTEX_LEVEL =20, what would be the effect?

anomolous "spiking" effects; in other words, instead of a gradual or smooth transitional rise or fall in a terrain feature, it will 'spike' at every relevant vertex intersection. hope that makes sense.
