Gamemastering

When my group and I started playing SAGA around 2015, I recall me and a buddy finding rules on how certain things were much more expensive in the KOTOR Era: Comlinks with Holo-projectors, Hyperdrives that went past x2 and Navicomputers.

I think we had settled on something like those costing four times the base cost, since such things were "state of the art", but never really made much use of those rules.

It's been a very long while, and between the WOTC forums going down and switching PCs I've lost track of a few things. I can't find these "rules" anywhere now. I guess my question is: were there ever rules for that sort of thing? I certainly can't find it in my KOTOR book, or anywhere else for that matter.

I swear I remember some years back reading somewhere a set of guidelines for creating high-level encounters for low-level players. Specifically, I recall it putting the example of the Bespin Duel, something about Vader only have +10 BAB and... I can't recall the Reflexes cap.

It was basically written so players could actually hit high-level characters, for whatever purposes have you. I can't seem to find the article/guide anywhere at all, and I would be extremely grateful if anyone either remembers what those alternative rules were or knows the text I'm talking about.

Sorry if I'm being too vague, but I really didn't know where to ask since the WOTC forums went down (in all likelihood it was somewhere there).
