Hmmm, I too always thought that those flags were global.
Are you trying to say that those flags also define when you access a field?
You could be right though...........Anyway, I just wanted to point out some things here.
The save games files actually do save which disc you are on so I'm sure this info is important in some way. Thus, I tried to make the first field file(the railway scene at the start of the game) into 3 savefiles. Each as Disc1,Disc2 and Disc3 respectively. Then I copied my movies to my hard drive. What's odd is when I get to a movie scene, where I first see the mako reactor, the game will crash if i use the save games from disc2 or disc3 but not with disc1. So, I guess the movies in the game only run on a per-disc basis. Even with all the avi files stored locally, the game still jammed.
2nd, thing. Assume I load an edited savegame with a party of lets say Barret, Cait Sith and Aeris(Seems stupid and likely to crash right) The thing is, the game will not crash. In fact it will still run normally. One thing which is special or rather what I'm trying to point out is your main character will usually not appear in the field screen. The field character is not missing, he's only just invisible; you can still exit the screens and interact with everything. The most important part is this: Upon entering certain field files, the character will actually be displayed and you will see him appear. Doesn't this mean that the possible people to appear in a field file is also defined?
