Creatures Caves

Hi folks, (Sorry this may be a long post)

Just started playing C1 again after a looooooong time (28 years ago, a time when i didn't have any interest in the technical aspects of it, nor access to the online community. I reinstalled the game on a computer 10 years ago or so but never really got to play again), and I have been reading a lot about the game, the mechanics, most what's available on the remnants of the community online for C1, which is way less info than C2/C3 or DS (which i have installed as well this time, but not played. Not yet. Not ever in my life before. Scandalous, right ?)

This time around, i've been reading/learning about the technical aspects of the game.
Started using the genetic Kit, to play with genes (added some to reinforce reward when complying to hand instructons in my norns, and modifief brain lobes to expand their neuron capacity... Basic things, really.
Although Ihaven't been able to judge on the effectivness yet, as i dived into a bottomless search/reading of everything i could find online on the C1 technical aspects right afterwards for the past 10 days or so (and might have browsed pretty much everything that is left of C1 content on the Web during that time frame)
While doing so I have installed the usual tools : BoBCoB, Spritist, a Hex editor, Visual Studio Code with the CAOS Creatures and Agenteering plugin, and opened much of the files i could with each of these, to get a general idea of what is what and how it is, which has been, depending on the app/software, interesting -COAS seems accessible enough with the available online help- or quite frustrating (Hex viewing some files can be pretty frustrating, even when part of the data is written in plain text), as i'm no coder.

With all the above, i have ended up with several questions, that may sound trivial/C1-ly uneducated/dumbs (afterall, i'm a complete newbie at all this), but here they are.

If i edit the Chemicals.txt or AllChemicals.txt or str, does it modify the ingame list of chemicals ? (and then you can play with them in the genetic kit for example, or work new mechanics ingame around them ?)

How to I extract data from games files (specifically : .sfc .exe or .dll) so they make a bit more sense : ex : i can identify the data for an ingame object in the file, or a creature, or a databse (ex nouns, verbs, class etc) so as to export it and modify it or make a script to modify it ?

If I expand the Noun lobe in size, does it increase the noun slots in the noun ddb (and then you can add other nouns in said expanded DDB) or do you have to extend the DDB, to then synch additionnal nouns slots to brain lobe neurons ? (and the same question applies to the verb lobe, of course) ?

I'm not sure i'm posting in the right forum, and i'm not sure if i'm clear in my explanations/questions or if any of you will have answers but hey, I'd really appreciate any info on the matter, as i find none in the forum (or elsewhere), as i'm not talking just about game mechanics here but deep diving into the way the game is built.
