Rather late, but I realized the 2 other RNG values:
*03005E08
*03005E10
Actually do affect battles. Naively recording the values of damage dealt with 03002C16 fixed at 0x5/0x24/0x3F will cause the outcome to be quite different than if you delayed input, and had the values for the above 2 change "as intended". Gonna see if I can figure out how to list the damage dealt in this case.
Edit: This ugly script:
Language: lua
memory.usememorydomain("IWRAM")
function version()
if memory.read_u32_le(0x0000A8,"ROM") == 0x574F5032 then
return "Power"
elseif memory.read_u32_le(0x0000A8,"ROM") == 0x45505332 then
return "Speed"
else
return "NA"
end
end

Moves are determined 5 frames after pressing A from whatever interface. Damage dealt and crits are determined a while after pressing A, after a bit of lag when the NPC does its attack sprite.
For the script to print out correctly, go to the frame right before one of the 3 things you want to know is determined, and make a savestate. Then run the script. This is sadly needed, since I can't figure out how 03005E08, 03005E10 advances based on the counter.
This also means it's technically possible to manipulate the battle a tiny bit by advancing the 2 RNGs from above before entering a fight. The good thing about this is that it's the counter (03000840) which seems to determine what Denjuu appears (they can group up).
I'm trying to manipulate the event that your ally appears before your turn, since it means I can hit twice.
