I was told it does not work with the walkthrough, but if I remember well, it was said it works with the gallery mod.
Sorry, no can't do for the walkthrough (I sound like Marc in the game
).
The walkthrough touches the rpy and the compiled rpyc files, but the incest patch also needs to create new rpyc files.
Effectively, the walkthrough modifies more heavily the code than the incest patch (though for coherence, in 3.02a incest patch I had to add an option in the dialogue with the "shrink").
It could possible to get the two to work together by taking the walkthrough and then using that version as base for the incest, but I am not the author of the walkthrough mod, so, I am not going to distribute it.
Then, it would mean having to integrate not only one source (the game with Prometheus patch), but two sources with the incest patch, plus, meaning having to wait for the update of the walkthrough to update the incest one, and having to create two incest patches, one for the version with walkthrough, and one without.
I already have to chase the "a" versions, because I always work on it as it comes out, and then comes again the "a" version, I cannot start to make "n" versions (though for that, in future I will just not bother with the default version, and wait for the "a" version, though it may mean delays in sending out the incest patch).
Nothing wrong in asking, but don't forget it is something I had started making for myself, I just made it available as a way to cut on all the polemic about "incest in or out" (often known as "bad Zorlun" polemic :-D)
