how does one navigate the PA.exe?

is it 7z or something similar?

PA.exe it's normal compiled executable that's not contain much built-in assets.

What for do you need to modify it?

apparently it contains the sound files and I need to check their names so I can remake this mod : https://forums.uberent.com/threads/rel-play-a-sound-on-new-lobby-chat-messages-51118.49838/

Are you totally sure sounds you need isn't inside FSB files in media/pa/audio/?
I seriously doubt Uber compiled any sound files inside executable.

all I see is '/SE/UI/UI_Alert_metal_low' so maybe "media/pa/audio/" is what they moved it too.

Actually they already renamed engine call you need.

Check "/media/ui/alpha/shared/js/api/audio.js". Most likely you need "playSound" method.

thanks got it to work

All audio is contained within the .fsb files in media/pa/audio/.
The audio paths (like /SE/UI/UI_Alert_metal_low) are how they are arranged inside the fsb's.

(Note the audio cue list may be a little out of date).

it's up on pamm now, I doubt there's much to change. thanks though ^^
