FF7/Materia Types

(This is a temporary page. It will be linked to from the Materia Data page when I'm done with it)

Materia is separated into five categories of functions in the game: "Command", "Magic", "Summon", "Independent", and "Support". Graphically they are yellow, green, red, blue, and purple respectively. The materia type is determined by a single byte value that is separated into two parts. The upper nybble will be considered the sub-type and the lower nybble is the base type. For base types the values will yield the following results:

Base	Materia Type
X0	Independent
X1	Independent
X2	Command
X3	Command
X4	Independent
X5	Support
X6	Command
X7	Command
X8	Command
X9	Magic
XA	Magic
XB	Summon
XC	Summon
XD	Independent*
XE	Independent*
XF	Independent*

* - There are no XD, XE or XF type materias in the game. They are graphically represented as Independent but have no effect.

Each of these Base Types have a set of sub-types that provide different functions: (If Subtype is listed as 'X' then any subtype will produce that effect. Other subtypes have no function)

Independent Types:

00	Function based on Attribute 1
	0Ch	0xC068B0 ORd with 1 and 0xC068B4 set to 11 (Underwater)
	62h	0xC068B0 ORd with 8 and 0xC068B4 set to 11 (HP<->MP)
201	Increases value at 0xC06898 + [Attribute_1 * 2] based on attribute list and AP level
302	0xC068B0 ORd with 4 and 0xC068B4 set to 12
40	Has a function, but is blacklisted at the beginning of the X0 type handler (handled elsewhere)

213	Enables effect Attribute 1 with a magnitude based on attribute list and AP Level
414	Enables effect Attribute 1 with a magnitude based on attribute list and AP Level

X4	If 0xC06914 is non-0 after getting AP level then set 0xC068B4 to 0Bh (Mega-All)

1 - Various in-battle conditions (Cover/Counter) and stat increases
2 - ONLY works with Materia Index 0Ch (Long Range). Attribute List is ignored
3 - Although Pre-Emp is a 21 type materia (and the only one), there is specific code to limit its magnitude in 41 as well.
4 - Enemy Away MUST be type 41 to work properly

Command Types:

12	Replace first command (Attack) based on attribute list and AP Level

X3	Subtype not important. Only Primary Attributes allowed are 15h, 16h, 17h
	15	Replaces Magic with WMagic
	16	Replaces Summon with WSummon
	17	Replaces Item with WItem
