so what exactly do I need to grab here?
Just whatever you want. I assume you just copy those package files into your mod directory.
Problem with this mod is all it does is give you color sliders for EA clothing and hair, and those are shit to begin with. I don't think its worth the huge file download. Just imagine it'd be several gigs to get it all and its a bulk download, you have almost no idea what you need since its all contained in merged package files.
You're better off just making your own color swatch if there is a certain EA item you like, 99% of ea items are shitty.
EA will just make a color slider anyways for their clothing eventually.
I personally think this guy selling this mod is a slimy character, he has used the hard work of TS4 Studio creator and also CmarNYC & tau534 who reverse engineered the new LRLE image format. To take their work, then to profit from that is really filthy stuff.
