===Sprite Tile Definitions===
3F30 to  3FB8 = Title screen data
Tile definitions for Townspeople/Hero Sprites: 0x1344


549F to  58D9 = Ending text
For the four tiles that make up the sprite (Top-left, Top-right, Bottom-left, Bottom-right), contains tile number byte, tile attributes byte (palette number 0x00-0x03, horizontal flip +0x40) for 8 bytes total.


5DDD to  5E58 = Chest data (See Note 3)
To calculate the sprite number, add these bits:
* Direction: 0x00 Facing Up, 0x20 Facing Right, 0x40 Facing Down, 0x60 Facing Left
* Animation Frame: 0x00 or 0x01
* Character:
** 0x00 = Man
** 0x02 = Adventurer
** 0x04 = Guard
** 0x06 = Merchant
** 0x08 = King Lorik (always facing Down)
** 0x0A = Old Man
** 0x0C = Woman
** 0x0D = Ending Guard with Trumpet (always facing Right)
** 0x10 = Hero (No equipment)
** 0x12 = Hero (Sword only)
** 0x14 = Hero (Shield only)
** 0x16 = Hero (Sword + Shield)

Multiply sprite number by 8 and add to base address 0x1344.

Gwaelin and Dragonlord normally do not face left, so they have glitched data in there.

Metadata entries are {{hex|5}} bytes long:

  02 = Pointer to map data
  03 = X size
04 = Y size
  05 = Border tile


10110 to 13FFF = Game graphics
===<span id="Song_Bytes"></span>Song Bytes===
</pre>
Song bytes are in the same order as maps.
(Byte {{hex|1}} plays for map 1, byte {{hex|2}} plays for map 2, etc.)
00 = Nothing
01 = Title Fanfare
02 = Throne Room
03 = Castle
04 = Town
05 = Overworld
06 = Cave 1
07 = Cave 2

==Notes==
===<span id="Title_Screen_End_Credits_Data_Format"></span>Title Screen / End Credits Data Format===
String format is 2 byte PPU address followed by the bytes to write to that address, terminated by $FC.
Both the title screen and the end credits use a slightly different table from the rest of the game with:
60=!
61=.
62=©
63=-
FC=[end of string]
/FD=[end of screen]


===Note 1===
Control code {{hex|F7}} takes 2 byte parameters (let's call them A and B) and means "repeat byte B A times" so e.g. {{hex|F7 08 05}} results in writing {{hex|05 05 05 05 05 05 05 05}} to the PPU.
Metadata entries are five bytes long:

01 to 02 = Pointer to map data
      03 = X size
      04 = Y size
      05 = Border tile

(Byte 1 plays for map 1, byte 2 plays for map 2, etc.)

04 = Chest contents

</pre>
===<span id="Menu_Format"></span>Menu Format===
Menu string format is menu setup parameters + menu text, where the menu setup parameters are:
* 1 byte menu type: bit 7 controls whether the menu has a cursor (1) or not (0), bit 5 controls line spacing (1 = single spacing, 0 = double spacing); the game code also checks bit 6 which then requires 1 extra setup parameter when set, but no menu ever sets bit 6
* 1 byte menu height: total height is this number of tiles x 2
* 1 byte menu width: number of tiles x 1
* 1 byte menu screen position: high nybble sets vertical position x 2, low nybble sets horizontal position x 2
If the menu has a cursor, then an additional two parameters are present:
* 1 byte horizontal offset of second column cursor position relative to left edge of menu
* 1 byte initial cursor position relative to top left menu corner; high nybble sets vertical position x 1, low nybble sets horizontal position x 1
The menu text uses a slightly different table from the rest of the game with (highlight to see trailing spaces):
80=[newline]
81=
82= 
83= 
84=   
85=   
86=     
87=     
and lots of other control codes for each of the different data to display.
{{note|There is no dedicated end token for menu text; the game keeps printing data until the menu space (width x height as modified by line spacing) has been completely filled!}}

The overworld map uses a strange system of pointers/auto-adjusts for offsetting the land from the start of the row. It can't be viewed simply by working out the RLE runs.

Note:
Much of the first CHR bank (0x10010 to 0x1056F, used for the title screen, final battle, and end credits) stores 2 different overlapping 1bpp graphics; palette changes make either one set of graphics or the other visible at a time.

Sprite Tile Definitions

Tile definitions for Townspeople/Hero Sprites: 0x1344

For the four tiles that make up the sprite (Top-left, Top-right, Bottom-left, Bottom-right), contains tile number byte, tile attributes byte (palette number 0x00-0x03, horizontal flip +0x40) for 8 bytes total.

To calculate the sprite number, add these bits:

  • Direction: 0x00 Facing Up, 0x20 Facing Right, 0x40 Facing Down, 0x60 Facing Left
  • Animation Frame: 0x00 or 0x01
  • Character:
    • 0x00 = Man
    • 0x02 = Adventurer
    • 0x04 = Guard
    • 0x06 = Merchant
    • 0x08 = King Lorik (always facing Down)
    • 0x0A = Old Man
    • 0x0C = Woman
    • 0x0D = Ending Guard with Trumpet (always facing Right)
    • 0x10 = Hero (No equipment)
    • 0x12 = Hero (Sword only)
    • 0x14 = Hero (Shield only)
    • 0x16 = Hero (Sword + Shield)
    • 0x18 = Hero (Carrying Gwaelin)
    • 0x1A = Princess Gwaelin
    • 0x1C = Dragonlord
    • 0x1E = Ending Guard with Trumpet (always facing Left)

Multiply sprite number by 8 and add to base address 0x1344.

For example, Tile Definitions for "Hero (Sword + Shield) facing Down" = 0x1344 + 8 * (0x16 + 0x40) = 0x15F4

Gwaelin and Dragonlord normally do not face left, so they have glitched data in there.

Data Formats

Metadata Format

Metadata entries are 5 bytes long:

01 = Pointer to map data
02 = Pointer to map data
03 = X size
04 = Y size
05 = Border tile

Song Bytes

Song bytes are in the same order as maps. (Byte 1 plays for map 1, byte 2 plays for map 2, etc.)

00 = Nothing
01 = Title Fanfare
02 = Throne Room
03 = Castle
04 = Town
05 = Overworld
06 = Cave 1
07 = Cave 2
08 = Cave 3
09 = Cave 4
0A = Cave 5
0B = Cave 6
0C = Cave 7
0D = Cave 8
0E = Battle
0F = Dragonlord
10 = End Theme
11 = Silver Harp
12 = Fairy Flute
13 = Rainbow Drop
14 = Death
15 = Inn Rest
16 = Princess Gwaelin
17 = Curse
18 = Battle (without intro)
19 = Victory
1A = Level Up

Title Screen / End Credits Data Format

String format is 2 byte PPU address followed by the bytes to write to that address, terminated by $FC. Both the title screen and the end credits use a slightly different table from the rest of the game with:

60=!
61=.
62=©
63=-
FC=[end of string]
/FD=[end of screen]

Control code F7 takes 2 byte parameters (let's call them A and B) and means "repeat byte B A times" so e.g. F7 08 05 results in writing 05 05 05 05 05 05 05 05 to the PPU.


Chest Data Format

Chest data entries are 5 bytes long:

01 = Map number
02 = X coordinate
03 = Y coordinate
04 = Chest contents

Menu Format

Menu string format is menu setup parameters + menu text, where the menu setup parameters are:

  • 1 byte menu type: bit 7 controls whether the menu has a cursor (1) or not (0), bit 5 controls line spacing (1 = single spacing, 0 = double spacing); the game code also checks bit 6 which then requires 1 extra setup parameter when set, but no menu ever sets bit 6
  • 1 byte menu height: total height is this number of tiles x 2
  • 1 byte menu width: number of tiles x 1
  • 1 byte menu screen position: high nybble sets vertical position x 2, low nybble sets horizontal position x 2

If the menu has a cursor, then an additional two parameters are present:

  • 1 byte horizontal offset of second column cursor position relative to left edge of menu
  • 1 byte initial cursor position relative to top left menu corner; high nybble sets vertical position x 1, low nybble sets horizontal position x 1

The menu text uses a slightly different table from the rest of the game with (highlight to see trailing spaces):

80=[newline]
81= 
82=  
83=   
84=    
85=     
86=      
87=       

and lots of other control codes for each of the different data to display.

Note for template.png
Note:
There is no dedicated end token for menu text; the game keeps printing data until the menu space (width x height as modified by line spacing) has been completely filled!
