From this we see that Fischer's early [chess960] activities were bunched into two time periods. The first period took place in 1992-1993, when Fischer developed the rules of his emerging invention. The second period took place in 1995-1996, when Fischer revealed his invention to the world. What happened in 1994 and after 1996? Looking at Fischer's other activities in those periods might help answer those questions.
Let's set a starting point at the end of the 1992 Fischer - Spassky Rematch; Sveti Stefan / Belgrade, IX-XI, 1992:-
1992-11-05: g.30, last game of 1992 match
Two of the links in the 'Early Evolution' post cover Fischer's subsequent travels. The first link is [Frank] Brady on Fischer Random (January 2011). There I wrote,
After the  match Fischer stayed in 'Magyarkanizsa, in the northernmost reaches of Serbia, on the border of Hungary'. There he made the acquaintance of the Polgar family and, with their encouragement, later moved to Budapest.
The second link is Chessmaniac, Comments on Chess960 (February 2015):-
'Bobby Fischer's Pathetic Endgame', where the original by Rene Chun is subtitled 'Paranoia, hubris, and hatred -- the unraveling of the greatest chess player ever' (theatlantic.com, December 2002). The portion covering the birth of chess960 takes seven paragraphs, which I'll quote in entirety...
The map below shows the main points in Fischer's travels during 1992-93.

see the map 'Eastern Europe (Political) 1993'
Budapest, in the center of the map, is circled. Southeast of Budapest, marked with an asterisk, is Magyarkanizsa [aka Kanjiza], on the border between Hungary and Serbia, not far from Szeged. The city south of Magyarkanizsa is Belgrade, which I haven't marked. Southwest of Belgrade, also marked with an asterisk, is Sveti Stefan, which is not far from Podgorica. In his book 'Endgame', Brady wrote (p.255),
1993-05: 'The Polgars, the royal chess family of Hungary, visited Bobby [in Magyarkanizsa] -- Laszlo, the father, and his two precocious daughters, Judit, sixteen, and Sofia, nineteen. Both girls were chess prodigies. (The oldest daughter, Zsuzsa, twenty-three -- a grandmaster -- was in Peru at a tournament.)'
Judit was also already a grandmaster. Zsuzsa [Susan] visited Bobby when she returned from Peru and convinced Fischer to move to Budapest. From there I'll continue the story in another post.
