I just want to use the better genetics without the personality cheats
Me too. But it is very bad at searching for hundreds of values. It fails even at 4 butt size related values. And tens for some personality aspects is just too hard.
You still can unguide in latest version: unguide, save, and restart game. You may also need to press Reset button for each pool to make it forget everything.
But I cannot recommend alternative genetics for personality. You can use enable button from screenshot to disable personality related pools, and use game's genetic algorithm. It will be more diverse.
While alternative genetics may look fun to watch, it completely ruins actual gameplay fun. I made some attempts to train AG through game's autorating profiles. With additional patches, it took 3k ratings to reach "Low" values instead of "Very Low" of sluttify or AG. And result was not very good(due to how profiles rate). I wouldn't call it low difficulty. And 3k ratings is not a thing you want to do by hand.
Good part, I'm making new thing: photo-rating. Drop few character portraits to auto-rating profile, and it will use them to auto-rate appearance and assist in character generation, so game wont run too far away from profile. Early results look promising, it still provides visual quality similar to AG, while using much less complex code. Another nice part, is that when it is used with sluttified template, it just gives easy start: game's 0 level models are so random, that it provides quite diverse output. And you can tune difficulty by dropping new portrait into profile.
I think I'll upload some demo after 0.9.8 or 0.9.8.1 leaks.
