So I was trying to get the WR for Solo Zonga and found out when I loaded my state (in the battle formation screen) that I would record from, my battles only took a few different paths. So I started investigating, and figured out that your battle "RNG" heavily depends upon when you start the battle. I believe this battle RNG seed is set when you hit Start!, and comes in cycles. I think this because when I started the battles on the exact same frame, I could go through the menu-ing RTA (meaning different inputs would be on different frames, which would make you think RNG would be different) and get the exact same result every time, down to the damage dealt by Squiro, the attack performed by the Z-Rex, and even whether I got a critical hit or not. This... is actually gonna be invaluable information to me when I TAS this game, but I figured you guys would find this interesting to know in your runs.
