You know what, I'm an idiot. I'd bet money that last place you end up right before HP and stuff ("A9" in Elite Wizzerd's data) is some sort of name index. If that's the case, then I can do this all straight from the ROM data, and there's no further testing required for anything but coins. Crossing my fingers...
EDIT: ARRRRGHH/YESSSSSS. Details later; might add more R's and S's if this is as good as I think it is.
For starters, a status List I found in the ROM; doesn't match up perfectly with data, but it's close enough to compare.
Poisoned
Sleepy
Stop
Dizzy
Confused
Stunned
Dodgy
Burned
Frozen
Huge
Tiny
Strong
Weak

Charged
Charged 9
Invisible

Cursed
Payback
Gradual HP
Gradual FP
Allergy
Instant Death
Change Parameters (I want a special that does this, now)
Mess 'Em Up
Instant Tasty Tonic
And an enemy list; again, doesn't line up perfectly with that A9 value, but it's probably going to help a ton. That's worth another couple R's.
