Omg this thread is a mess since the site migration and I don’t know if I can fully redo all the information. I’ll try over time, but no promises.
Finally decided to list all of these in one place rather than in a Twitter thread. Here I’ll sort it by date, include images of the covers, and link to any scans if there are any.
I’ll include any related Japanese terms to make them easier for people to search. For example, “Chocobo’s Mystery Dungeon Xenogears VJump” in Japanese, even if that’s not necessarily the title of the magazine (what even is its title anyway?).
Search in Japanese for dates like 1997年11月18日 (1997 November 18th), for example, with each number before their respective kanji.

月 - Month
年 - Year

Interestingly, on one of the pages it calls Zohar the 事象変異機関 “Event Mutation Engine”, 1 kanji off of the final script’s name for Zohar, 事象変移機関 “Event Alteration Engine”. This could just have been misheard from one person to another though, as 変異 and 変移 both have the same readings.
Anywho, it says Zohar is being used to terraform planets, which is very interesting, that this could’ve very well been legit, that in the beta script Zohar could terraform planets. And the fact that in the final script (in PW) Zohar is on the station of Miktam04β as the planet is being terraformed.

The scans I got are here under the folder Xenogears>Images>Scans>Chocobo’s Mystery Dungeon VJump; some of the transparent versions of scans have been edited beyond simply cutting them out. If you’d like pictures of it of pages that I have yet to scan, let me know.

One of these pages describes the language that Elly speaks in the forest as not being gibberish and how it can actually be “translated”.
“The rule is that the Arabic official language Fusha is translated, then converted into the alphabet, and then read backwards in German. Here is the full text of what Elly says when she meets Fei. Using this as a basis, try translating other lines as well!?”

It’d be so awesome if we could preserve the high poly models like this, especially the XG Gears that we most often only see in low quality scans. Like that one render of Weltall-Id only seen in one small image in PW that’s also half opacity 
Makes a lot more sense now, considering just how much info they had in them.
