Bero, KingClubber, and I figured out how every single AI file works, and I wrote a program (leveleleven, unreleased) to edit them, and Bero wrote AIScriptPad. You can edit pretty much 80% of the games AI code now, with the remaining 20% being scattered in ASM in the game itself.
placebo. The game never uses a constant greater than the one used for level 9's in the AI coding, and it clamps values between the ranges it expects when it uses the difficulty value.
If you specific a memory offset, add something like "vBrawl P1 training mode" to let people know how you got them. Those should be the pretty constant.
