Graal: The Adventure/ROM map

NPC Data

Usually comes directly after Palette and Exit Data. I am still trying to find a pattern so we can edit and find NPCs easily.

Level 2 - Crystal Tree Thing:

• 1188D = NPC #1 Direction
• 1188E = NPC #1 Appearance
• 11892 = NPC #1 Walk or not (0/1)

Level 3 - Waterfall doesn't Belong here:

• 1483F = Sign # (Which Sign do they say when they are touched. It's somewhat based on PC version's way of NPC talking.)

Level 6 - Two Baddies:

• 120BB = Top NPC's Appearance

Level 3's Exit and NPC Data Analysis

 0C1F0901FF01020006001901FF1F0600 ; This all seems to affect warp zones. The last 00 might be the sign's index number.
 20202020202020202020202020202020 ; Sign Spaces, used to make it centered
 20202020202020283F4646495F202020 ; "Hello!"
 2020202000000010481A050206030100 ; Spaces, ends with 00s... 
 000021012280030000190B0003030100 ; This slab must be the NPCs
 000021012280030000040B0306030100 ; as they all are nearly identical "030100" seems to start a new NPC.
 00002101228003000000400000020048 ; other than a few digits.
 013548033948                     ; Unknown

Level 4's Exit and NPC Data Analysis

 061F1901FF0105000B1002010C1C0100 ; Again, this is Warping, The 00 is still at the end.
 20202020202020202020202020202020 ; Spaces for the sign, again
 202034423B4E674D2053494F4C204249 ; Sign stuff, again
 4F4D3F5F0006168650171A01050301FF ; Unknown... "0301FF" at the end must be part of the NPC data.
 010021012280030000091303040301FF ; Noticeably similar to above's NPC data
 01002101228003000076480000027650 ; With differences.
 01AB5002AF50

Comparing both together

So in thoery, full NPC data looks like this:

 030100000021012280030000190B0003
 (In bold is changed values)

• 030100 or 0301FF are always before an npc. Probably to define that it is an NPC.
  • 00 and FF are unknown switches At the Moment.
• 0100 might mean walk, while 0000 might mean static (non moving).
• 190B, listed above, is Coordinates when the level is loaded, 99% positive it is.

* The last 4 digits, listed above are 0003, they are different for all NPC, not sure what it does.

The last four digits:

• The first two digits MIGHT be the direction they are facing.
• The last two digits seem to be a appearance modifier.

Level Data

• 10000 = Level data officially starts, with 0E unknown bytes.

• It's confirmed that it's not a header, Level 3 doesn't have any 0xE before.

 59486E509B58D860DF696948CF50

Every Level is a total of 0x400 bytes starting at the starting point for tiles and palettes/properties.

Level 1 - Starting Point:

• 1000E = Start of Tiles GFX
• 1040E = Start of Palette

Level 2 - Crystal Tree Thing:

Level 3 - Waterfall shouldn't be there:

• 14000 = Start of Tiles GFX
• 14400 = Start of Palette

Level 4 - Two NPCs and a house

• 14876 = Start of Tiles GFX
• 14C76 = Start of Palette

Level 6 - Two Baddies

• 118A8 = Start of Tiles GFX
• 11CA8 = Start of Palette

How it's numbered

 LEVELS ARE NUMBERED AS FOLLOWS (Location to number, etc.)
 
   5
 7 4
 6 3
 1 2
 
 Level 2 is the Crystal, etc.

How levels are made

Each level is 0x400 bytes for both tiles and palette/properties.

Each level should look like this:

1F Hex Values wide, 1.00 KB in size. Each Hex Value is a new 8x8 tile. To make a bush, in the map, put in the following:

 191A
 1B1C

That will produce a File:Graalbush.png

How Palettes and Properties work

Much like the Tileset of a map, Palettes are also 0x400 bytes. However, they define Horozonal Flip and color in a byte and basically correspond to the tile map. So 1,1 in the tile map would be 1,1 in the palette map, etc..

To make a simple green tile: In the tile of choice, put in 00 To make a simple flipped green tile: In the tile of choice, put in 20

Meaning, the first digit is the property, the second digit is the palette.
