GRA notes

Sample header:
   00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
   _______________________________________________
00|00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 
10|00 1A FF FF FF FF FF FF FF FF FF FF FF FF 00 00
20|00 04 4A 41 53 54 00 00 01 E0 01 29 
        ( J  A  S  T)
The header width seems to change based on the file.
Some match perfectly (See ST15.GRA and ST14.GRA), 
others seem to be two bytes shorter per column 
(ST24A0.GRA). This section of the header however 
does NOT contain the palette. It may contain 
animation data...? The first 32 bytes appear to 
be completly worthless.

These files are compressed.

They seem to be 16 colors, with the palette written
in to the file. This has been determined by taking
a screenshot of indvidual scenes vs the whole 
screeen.

lobster|z seems to think its an altered version of
a GIF file, which would make sense considering the
age of the game. The main fun is figuring out which
version it is. gif89a and gif87a format specs 
have been uploaded for assistance.

--- Current task ---
The best solution I can find at this point to 
determine the format is to re-write the file's
header to match a GIF header, and load it in 
a program. If its corrupt, try the other version,
if its STILL corrupt, well... Shit.

Footer: 
00 00 00 00
GIF doesn't have a footer, so this is somewhat
suspect data. Perhaps other information is
(sometimes) stored here...?
