try UDK.exe -language=DET instead
again though, not guaranteed to work
anyway as I said, I’m making it all custom-made and I won’t be using the included localization functonality.
the downside is I have to make my way around getting the right language for each word/phrase manually, aka. my own localization functions
the upside is I’ll be able to change it from within the menu without needing to restart the game, or any command line stuff.
I’ve found a way to hijack SoundCue subtitles which will be super useful to parse and localize them before printing them out
