At 0xC1638 are subtitles for the intro cutscene which aren't used.

From the deep reaches of space, a horror approaches.  Once, in a great while, 
the malevolent forces of the universe combine to form a force of evil so concentrated,
so pure, that no bastion of goodness and decency can stand against it. It hurls through 
the universe toward its destination.  The planet: Earth.  The town to be victimized? South Park, Colorado.
A quaint little town, nestled in the peaks of the Rocky Mountains.  Where better to terrorize good and descent folk.          
Yeah, right!

At 0xC0230 and 0xC144C are more unused subtitles for Operation: Turkey Butt's and Some Disassembly Required's post-final boss stage cutscenes for the respective episodes.

That turkey didn't know who he was messing with.
Hey, you guys. Cartman's eating the turkey's butt!
Sick, Cartman!
HEY! I am not eating the turkey butt!
you son of a bitch I'll kick you in the nuts!

Only the second line is shown in-game.

And then Eric destroyed the King Toy, saving all the toys from evil.
Wow!
Eric is so strong and brave, he is so cool. Hey, that's cool isn't it!
Shut up kitty you dildo, I'm a hero!

None of these subtitles show up in-game.

Interestingly, there's even unused lines evident within these unused subtitles. The line "Sick, Cartman!" is replaced with Kyle and Stan laughing along with a subtitle simply reading "(Laugh)", and there is no line said at all between the first and third lines in Batteries Included's cutscene.
