This is a minor complaint. I noticed when I first started that the emails and logs in this game have different text than the original version that System Shock Portable used to run off of. (i.e.: Portable's logs and email had text set exactly to the audio, just like subtitles) In the Enhanced and even the Classic edition, this text doesn't match the actual sound of the person speaking. And I don't understand why.
is there a way to put the old text back without having to switch back to SSP? I like to listen to audio with subtitles, because I can't always catch what people are saying right off the bat, especially when they have serious accents or there's a lot of background noise.

I played SS only recently and I thought it was supposed to be that way to be honest. Since that is isn't the case, maybe the text comes directly from the floppy version were it was different than the audio of the CD-ROM version? Not really sure...

Read about this mod.

What you've been reading in the GOG versions IS the original text. Originally, the game was released on floppy disks (something about the publisher being in a rush to have the game in stores in time to catch some of those sweet year-end sales), so there were no actual voice-overs for the audio logs -- just text. When they later recorded the voice-overs, they didn't bother to make them adhere exactly to the text versions of those logs, as long as the salient information was the same; nor did they re-write the old text versions of those logs, probably considering it a waste of time and resources, assuming (reasonably, though incorrectly) that most players would either read OR listen, not do both.
The discrepancy between text and audio never really bothered me, but it was enough of an issue for others that someone created a mod that "fixed" the discrepancy. You must've been playing SSP with this mod in effect.

yay for ocd modders XD

Thanks, that helped me straight away. Now I can play while not feeling distracted. :)
