Possibility of patching only modified files

Possibility of patching only modified files (maybe?)

I have an idea that requires me to create patches consisting only of modified files. I have no idea yet if this makes any sense or if it will even work in the game.

1. Is it even possible to create a patch that doesn't include unmodified files?
2. If you make a patch with only the modified voice lines of the Eagle-1 pilot, will it sound like emptiness throughout the entire mission, interrupted only by the pilot's lines?

The Write Patch option when you make a mod should already only include modified files. For example, if you only mod 1 Eagle voice line, the output patch will contain only the modified line and the eagle soundbank.

This results in only the single line being replaced, and all others are unchanged.

and all others are unchanged.

My question is, is it possible to not include unchanged voicelines in the patch file?
Am I correct in thinking that when we change the Eagle 1 pilot's single line and when we don't change any lines at all, the patches contain the same number of voicelines?

If you don't patch an audio, it will play the original one. Think of the patch as an "alternative path" for an audio. If an alternative exists, play the alternative, otherwise play the original.

Based on what you wrote before

If you make a patch with only the modified voice lines of the Eagle-1 pilot, will it sound like emptiness throughout the entire mission, interrupted only by the pilot's lines?

If you want to remove the other voice lines so you only have the eagle and other lines you decided to change, you will need to basically patch all the other sounds, replacing them for a silent sound file.

This is not entirely correct. Changing 1 line for Eagle will only result in that single line being included in the patch file. Changing 2 lines will result in those 2 lines being included in the patch file, and if you don't touch Eagle's voicelines at all, none of them will be included. Other types of audio (like SFX and music) do require all unmodified audio to be included in the patch, as these other types of audio are stored in a different way (though if you mod nothing it will not include them). In the case of SFX and music, any audio that is not included in the patch will be deleted from the game.
