1 byte: Style of table. 02 = 2-dimensional
1 byte: Value offset (a fixed value to add to every raw table element)

Tables - 8 bit format, 3-Dimensional

1 byte: Style of table. 03 = 3-dimensional.
1 byte: Value offset (a fixed value to add to every raw table element)
2 bytes: Source X Scaling Variable Address (relative to fp)
2 bytes: Source Y Scaling Variable Address (relative to fp)
1 byte: Number of rows (or columns... I forget)
...
...then the table data.

There are some weirdo extra formats that crop up in later year ROMs (eg. 2011), but the above will cover 99.9% of all data styles.

If any typos have snuck in, let me know and I'll edit to fix.

00 06 33 AA 00 06 33 C8 header in a 16 bits / 3D table

Does anyone know what it means?
