I had found the breakdown of the stadium registered team save structure in another (very old) post on this forum. And I can pick out pieces of relevant data in the memory. Looking at the top photo, start with 1C (Blastoise's index number).
1C Blastoise
0135
64
00
15 Water
15 Water
5F
5E Psychic (I used a gameshark)
38 Hydropump
08 Ice punch
3B Blizzard
00B9
FB0010
2C14
696C
6FAF
6C13
6EDE
6A3A
EAAA
D0
C8
D8
C8
The rest kind of loses me - though I do see my OT 8A9287 (ASH) a bit further down. So I think the data is here, I just lack the skills to translate the rest of it.
