That's a nice idea. Based on your comparison between start and end savemaps, which bytes changed? How many were left on 0?
My notes were really crappy and done before I even used Makou.. I just wanted a rough idea of how many bytes were actually NULL compared to actual unknown so I could plan my mod a little better (the conclusion was I had plenty of space
). I checked the z_ unknowns from that savemap link in black chocobo and marked the positions of the nulls across several saved games in the samples folder. I'm not sure how it matches up with your chart or Makou.
The format is basically:
0x0BAB 17 Z_8 Unknown 0, 3-8, 13-16 look null and unused
17 lists the number of unknown bytes, Z_8 is the unknown place in black chocobo, Unknown just means its Unknown (sorry, didn't bother removing it), then the numbers indicate which positions are NULL - I just noted them as "look null/appear null/unused"
0x0BAB 17 Z_8 Unknown 0, 3-8, 13-16 look null and unused
0x0BB4 16 Z_9 Unknown 0-3, 6-15 look null and unused
0x0C20 4 z_15 Unknown – Only 0 appears unused
0x0BD6 14 Z_10 Unknown, 0, 2-5, 10-13 look unused
0x0BF8 1 z_12 Unknown – looks unused
0x0BFD 2 z_13 Unknown – both look unused, 0 and 1
0x0C20 4 z_15 Unknown – Only 0 appears unused
0x0C24 97 z_16 Unknown – a lot seem null, but some are used inbetween. Null values: 1, 8-31, 44, 47-48, 54, 61, 65, 67, 72-95
0x0C87 29/45 z_17 Unknown[0-28] First 29 bytes of 45 (ENDS AT 0x0CB3 16 Bytes into next bank) 1, 7, 9-38, 41-44 look unused
0x0CA4 16/45 z_17 Unknown[29-44] Last 16 bytes of 45 , see above. 1, 7, 9-38, 41-44 look unused
0x0CB5 49 z_18 Unknown 10-46 look NULL and unused

0x0D47 31 z_24 Unknown most used except 4, 13, 20, 24

0x0EA5 1 z_31 Unknown Data (used)
0x0EA7 3 z_32 Unknown only slot 2 appears unused NULL
0x0EAC 22 z_33 Unknown All seem unused and NULL!
0x0EF5 23 z_35 Unknown 3 to 9, 11-12, 14-15, 21-22 appear NULL
