FF7/Materia Types
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 | Independent1 |
| XE | Independent1 |
| XF | Independent1 |
Each of these Base Types have a set of sub-types that provide different functions. They are used to determine what function to provide, usually based on the Materia's attribute list. These sub-types are: (If sub-type is listed as 'X' then any sub-type will produce that effect. Other sub-types have no function)

1 - There are no XD, XE or XF type materias in the game. They are graphically represented as Independent but have no effect.
2 - Various in-battle conditions (Cover/Counter) and stat increases
3 - ONLY works with Materia Index 0Ch (Long Range). Attribute List is ignored
4 - Although Materia Index 0Ah (Pre-Emp) is a type 21 (and the only one), there is specific code to limit its magnitude in 41
5 - Although Materia Index 07h (Enemy Away) is a type 41, there is code for that index in 21
6 - Shield is the last magic attack with an index of 35h. The Magic menu prevents access to attacks 36h & 37h
