View source for 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 type materias in the game, but there is a function to handle them though it will not be called.
** - There are no XE or XF type materias in the game, but they will be graphically represented as Independent and will have no effect.

Each of these Base Types have a set of sub-types that provide different functions:

 00	blah
 01	No Effect
 02	blah
 03	blah
 04	Not used

Other values invalid for base type X0
