In the process of finding out every value of the savemap, I'm playing through the game making all the possible combinations. For example, between a save point A and B there are two chests and an item, I make it first taking nothing, then one chest, then another chest and so on until the last save is taking everything.
That way is easier to know which values change what by comparison.
I'm posting here the saves so anyone who wants can lend a hand and start finding out values while I do the playthrough. Right now I'm starting to raid the Shinra HQ.
About the playthrough:
Used blackchocobo to put Cloud at level 99 with max stats so i can go faster.
Changed the text speed.
Changed the key mapping.
Turned the field help on (In some saves its off).
Didn't use hacks (yet) to make saves where the game doesn't let you.
The version of the game is the spanish one so the names of the save locations will appear in spanish
About the information:
Saves in green are completed.
Saves in orange may need a save hack due to long scenes taking place.
Saves written in bold letters are saves corresponding to the main path. Saves inbetween the bold ones are just combinations that don't progress further.
Saves in blue dont follow the linear progression of the game.
Saves in red are mistakes and don't count.
Saves can be downloaded HERE (part 1)

Any help is appreciated
EDIT: Finished Midgar, updated the links with the latest saves.
