We don't have it for either Gen.4 or Gen.5, and it's making it hard for me to tell what's what when it comes to the held items, egg groups, etc.
But, from what I've seen so far, it appears to be the following:
+0x00: Base stats (6 bytes)
+0x06: Types (2 bytes)
+0x08: Catch rate (1 byte)
+0x09: Evolutionary stage? (1 byte)
+0x12: Gender ratio (1 byte)
+0x22: Base EXP yield (2 bytes)
+0x24: Height in 0.1 m (2 bytes)
+0x26: Weight in 0.1 kg (2 bytes)
Umm... I don't know the rest. Here are some patterns, though:
+0x13: Some strange property that's always a multiple of 5. It seems to be set at 120 for most legendary Pokémon.
+0x14: Some strange property that's always set to either 0, 35, 70, 90, 100, or 140.
