-Initial, 22 Dec 2008: Appears that each stat block in the save is A0 bytes long. I'm not sure whether they start at 200h or 202h, though. I'll assume it's 200 for simplicity's sake, for now.

All values hex unless otherwise noted.

Block Addresses (Beginning):
0x200+(index*A0) (202?)

Bytes 00 and 01 of the char status blocks are located in byte 03 here (202, etc.)

If a value exists in parentheses after the character's name, it indicates that a value other than 00 was found at byte 00 in my 'B' Red save. In brackets indicates a still different value found in save 'A' (B being taken with 1 battle and 10 idle minutes of difference compared to A).

0200: Emelia (4B)
02A0: Lute
0340: Red (HP: 0x347)
03E0: Fuse (BF) [BE]
0480: Blue (06)
0520: Asellus 
05C0: T260
0660: Riki
0700: Rouge
07A0: Roufas
0840: Gen (05)
08E0: Fei-on
0980: Annie
0A20: Liza (06)
0AC0: Capt.Hamilton
0B60: Doll
0C00: Mei-ling (44)
0CA0: Woman
0D40: White Rose
0DE0: Ildon
0E80: Mesarthim
0F20: Zozma
0FC0: Rei
1060: Silence
1100: Dr.Nusakan
11A0: TimeLord
1240: Rabbit
12E0: Leonard (92) [91]
1380: ZEKE
1420: BJ&K
14C0: PzkwV (3B)
1560: EngineerCar
1600: CommonMec (31)
16A0: Thunder
1740: Cotton
17E0: Sei (31)
1880: Kylin
1920: Slime
19C0: Suzaku
1A60: RedTurnip
1B00: Alkaiser..in theory (no data here, same as INITDATA)

So Fuse and Leonard have values that appear to increase, though that could be an isolated occurence.

In my Red A save, I found the word 'Red' at 1B10.
Likewise, same address, 'Asellus', in my Asellus file.
In T260's save, it's T260G, so I think this is the displayed name.

Unfortunately, I'm not cool enough to make PSX Game Edit put the saves back in after I've changed them.. >.> I thought I'd modified it by working with the actual memcard file directly, but now it won't load (just that save). When I did it this way, there were 2 instances of Red followed by 20202020202020 (padding bytes for names). Changing the second one caused the file to not load in ePSXe, changing the first seemed to do nothing.
