AA2 character data format

I'll try to detail some of my findings of the AA2 character data file format here as I'm working on it for my online AA2 trait editor (http://aa2.zawiarr.com). I did most of the work charting this info myself, but some fellow anons in /hgg/ helped out initially so big thanks to them.

The data is stored inside a PNG container, and all offsets are based of the first IEND (49 45 4E 44) of the file. All values are in hex (0x) unless otherwise specified.

| Offset | What                 | Length | Value/Info
+--------+----------------------+--------+-----------------------------------------
|      0 | PNG IEND             | 4      | (49 45 4E 44)
|     1D | Last name text       | 104    | Null terminated, so effectively 259 characters max. Text format info below.
|    121 | First name text      | 104    | Same as above.
|    225 | Profile text         | FF     | Editor says max 255 chars, but keeps reading if not terminated.
|    692 | Intelligence         | 1      | 00 to 04: Lowest -> Highest.
|    698 | Strength             | 1      | 00 to 04: Lowest -> Highest.
|    6A3 | Sociability          | 1      | 00 to 04: Lowest -> Highest.
|    6A4 | Fighting style       | 1      | 00 to 02: No restraint, One blow, Irregular.
|    6A5 | Virtue               | 1      | 00 to 04: Lowest -> Highest.
|    6A6 | Sexual orientation   | 1      | 00 to 04: Hetero, Lean hetero, Bisexual, Lean homo, Homo.
|    6A7 | Sexual experience    | 1      | 00 or 01 (False or True)
|    6A8 | Anal experience      | 1      | 00 or 01
|    6AA | Character traits     | 26     | There are 38 traits each one byte, value is either 00 or 01. Order same as in the editor.
|    6D0 | Rainbow status       | 1      | 00 or 01
|    6D1 | Sexual Preferences   | D      | Same as the traits, but only 13.

¤ These are the confirmed values for now. I assume most of the other follows roughly in the same order they are presented in the character editor, as that seems to be the common pattern. I will edit in more values once I have confirmed them properly.

Text format
------------
The text format was a real pain to figure out. The text is coded in japanese Shift-JIS encoding, and then all the bytes are flipped for some weird reason I really don't understand. So to read it back you first need to extract a text block, then do a bitwise inversion on all bytes (xor FF or ~). You then get Shift-JIS (where ASCII is readable at least) which can be converted to something actually useful (UTF-8). To write back you just reverse the process. Also note that since this seems to be using C-strings you should terminate all text with null (\0) before inverting (or FF (~\0) after the invert).
