===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) | |||

** 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== | |||

== | ===<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] | |||
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. | |||
=== | ===<span id="Chest_Data_Format"></span>Chest Data Format=== | ||
Chest data entries are | Chest data entries are {{hex|5}} bytes long: | ||

02 = X coordinate | 03 = Y coordinate | ||
03 = Y coordinate | 04 = Chest contents | ||
04 = Chest contents | |||
</ | ===<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!}} | |||

- 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: 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! |
