Wassaperwaffle everyone, i got problems with my NV ingame when i change my keyboard buttons it will revert to default everytime i open the game. So i took alook in some Falloutprefs.ini and found the controls section but it translate to somethign like
bAlwaysRunByDefault=1
bBackground Mouse=0
bBackground Keyboard=1
Forward=0011FF13
Back=001FFF14
Slide Left=001EFF17
Slide Right=0020FF16
Use=00FF0011
Activate=0012FF0A
Block=00380110
Ready Item=0013FF0C
Crouch/Sneak=001DFF08
Run=002AFFFF
Always Run=003AFFFF
Auto Move=0010FFFF
Jump=0039FF0D
Toggle POV=0021020F
Menu Mode=000FFF0B
Rest=0014FF07
Vats=002FFF0E
Hotkey1=0002FFFF
Ammo Swap=0003FF01
Hotkey3=0004FFFF

idk what these codes are and am wondering if there is a way to translate it to normal keys so i can play normal again. Please let me know!

Wow, I've never seen anything like this. I think your FalloutPrefs.ini might be read only. Right click it, go to properties, and uncheck read-only.

yea, ive tried that but it didnt work

Do what YeezusJeezus spoke, but with the 3 ini files, Fallout_default.ini ; FalloutPrefs.ini and Fallout.ini .

I believe it's Fallout_default.ini that you need to change. Every time you use the game launcher, it resets everything based on the settings in that file. Read-only permissions shouldn't make a difference.

Here's the default mapping:

Spoiler:

It looks like your setup is fine. Try adding these lines between fMouseSensitivity and [Water] so that the launcher doesn't change it (and don't forget to back your ini files up before doing anything to them). Make sure there aren't any duplicate entries, and you should be good.

Something else comes to mind... you say the changes you make while playing don't save.  Is it possible you quit the game using ALT+F4 or QQQ or something similar?  If so, try launching the game with the vanilla launcher, make your changes and quit via the menu.
