doesn't look that hard
$D83316 has 8 bytes per menu, and I've only seen the first used which tells that "menu" what id has is the first spell.
the second byte looks like the last spell "id" of each menu but that value doesn't seem to be used at all.
ok, not that simple.
$0 to $5E are the same number as the spell ids used.
$5F to $7C map to $82 to $9F (blue magic).
of course they are only loaded if you "know" that spell, by spell level, buying/finding/learning, etc.
$80 or higher read from wrong data so the shown spells are more or less random.
at least white and red have completely separate entries and then used asm routines.
In case of white it comes from $C1/37BA BF 16 33 D8 LDA $D83316,x[$D8:331E]
I may not even have to move !white at all to the red menu table.
$7E:41B2 tells which ability is currently used, so just smuggle a little if in there...
also, another table at $C0EEF4, 3 bytes per entry, unless the first byte is $ff, that is the signal for list ends
this tells the game which spells are usable in the menu and what they do
first byte is the spell id
called from $C2/DEDE
We have EVEN MORE themes now, but some old ones are gone...
