I've been surprisingly involved in some amount of modding recently and thought I'd make a small detour in the wasteland of compatibility that you guys have been facing with Portal: Prelude the last few years, between all the changes to Steam and the Source engine. Let me know if you spot any issue.

What text-to-speech programs did you use for the voice acting

Do you mean what software I used 15 years ago when this was released? Probably something that doesn't exist anymore. Today, Google exposes a Text-to-Speech AI that is quite good: Cloud.google.com

Yes, what text-to-speech software did you use for the voice acting? Oh, and do you plan on replacing the text-to-speech with real voice actors?

Found it: Acapela-box.com

Odds are some of you in more recent times have also heard the TTS voices used in a few memes.

Some of the scientists voice lines are silent...

That's on purpose to remove some offensive lines that were less of a concern in 2008.

Hi, I'm running this mod without steam but I have SDK 2013.
I tried to run it but it gives gameinfo error.
If I somehow manage to run it (by renaming folder to "portalprelude" , the mod works but the chapter names are glitched.
So I have a request, can you make mod folder name to a single word instead to two words, like I mentioned above?
Thanks.
Btw, amazing mod, I loved it !

Sorry, not a supported setup. Use Steam and Portal.

If I want to fix the chapter names, what files should I edit?
