You can get a great description from SVR's web site
I have also previously prepared the following info about the "gf chunk":
D2 V1.10 Beta – information for dynamic decoding for character stats
After “gf” header (67h, 66h) @ (2FDh,2FEh), look for the value of the next 9 bits (starting at 2FFh), to determine any extra stat ID bits, followed by the stat bits:
0: 9 bits, + 10 bits Strength
1: 9 bits, + 10 bits Energy
2: 9 bits, + 10 bits Dexterity
3: 9 bits, + 10 bits Vitality
4: 9 bits, + 10 bits Stat Points Remaining
5: 9 bits, + 8 bits Skill Choices Remaining
6: 9 bits, + 21 bits Current Life (/256)
7: 9 bits, + 21 bits Maximum Life (/256)
8: 9 bits, + 21 bits Current Mana (/256)
9: 9 bits, + 21 bits Maximum Mana (/256)
A: 9 bits, + 21 bits Current Stamina (/256)
B: 9 bits, + 21 bits Maximum Stamina (/256)
C: 9 bits, + 7 bits Level
D: 9 bits, + 32 bits Experience
E: 9 bits, + 25 bits Gold on Person
F: 9 bits, + 25 bits Gold in Stash
Example, ‘forward bytes’, after “gf” header:
00 28 08 F0 80 00 0F 06 50 40 40 81 02 01 06 00 70 C0 01 00 1C 80 00 70 02 24 00 9C 00 0A 00 AE C0 02 80 2B C0 80 D0 A0 10 03 00 C0 81 16 00 80 07 08 00 00 FE 03
Reverse order of the above example bytes:

Decoded values for Example:

1: Energy = 15
2: Dexterity = 30
3: Vitality = 20
4: Stat Points Left = 10
5: Skill Points Left = 1

8: Current Mana = 19
9: Maximum Mana = 19
A: Current Stamina = 87

C: Level = 4
D: Experience = 6277
E: Gold on Person = 90
F: Gold in Stash = 8
