RM2k XYZ Graphics Format
Simple documentation file v1.0 by Janus (janusfury@citlink.net)

Header:
4 bytes: XYZ1
2 bytes, unsigned int: Width
2 bytes, unsigned int: Height

Data:
ZLib-compressed. Use ZLib.dll uncompress to decompress it...
The output size of the data is (image and palette):
(Width * Height) + (256 * 3)
The input size of the data is:
FileSize - 8
In english, the data starts after the header and ends at the end of the file, and the image, when decompressed, is just a palette and then image data.
The palette is simply a series of colors in RGB order, no 4th byte for the palette entries.
The data is just a bunch of palette indexes, in standard x,y order.

Enjoy! :)
