Battle spell table

During battle startup, the spell list is compressed and stored for each character. The table starts at $208E and each spell (and lores also) takes 4 bytes:

1. Spell id
2. Spell availability (see function C2/5763).
3. Aiming byte (from $C46AC0 + 14*spell_id)
4. Spell MP cost (from $C46AC5 + 14*spell_id)

Here is the content of the spell aiming byte:

• Bit 0 = Cursor Moveable
• Bit 1 = One Side Only
• Bit 2 = Autoselect both parties
• Bit 3 = Autoselect one party
• Bit 4 = Auto Confirm
• Bit 5 = Manual Party Select
• Bit 6 = Cursor Start on Enemy
• Bit 7 = Randomize selection

Here is the list of all aiming bytes available and the corresponding spells:

• 0b00000000 (Self): Warp
• 0b00000001 (Allies or enemies, single): Safe, Haste, Bserk, Rflect, Shell, Vanish, Life, Life 2

• 0b01101110 (Enemies, multi target): Quartr, Meteor, Ultima

At the battle startup and after each turn, function C2/083F is called. For a given entity, if his Imp status is toggled, the attack/spell costs him MP to cast, or the attack itself affects his MP because he's a target [or the caster, if it's a draining attack]), then it updates availability of entries on Esper, Magic and Lore menus (function C2/5763).

In function C2/5763, carry is set if Imped and spell not Imp, or insufficient MP. Then, spell availability is rotated right, putting the carry in bit 7.
