where are the ui button files located

[grantgto101]

I am trying to mod the interface so a made the mod using adobe PS, but the start, load, record etc buttons are still the default. I tried changing it in the start.ui but still the default buttons: !:

I'm guessing the buttons, like a lot of other images, might be in the tex#.dds files, referenced by itextures.dat. You'll have to check by yourself though, I don't have access to the files atm.
