The Thalion Source - Ambermoon

Savefiles
There are up to 11 savefiles; number 01 to 10 are your savegames, while number 00 is the start game. When saving a game, it will be saved one time in the Save.XX directory in JH-encrypted form and another time unencrypted in the main directory Amberfiles, except the Party_char.sav that will be encrypted as well. So you can change the save file in the main directory and copy it back into a Save.XX to change files, without having to deal with encryption. In fact, the game doesn't seem to care in any case if a file is encrypted or not, it merely has to contain the right entry data.

Maps (1Map_data.amb, 2Map_data.amb, 3Map_data.amb)	All the world/2D/3D-maps. Each entry is a fragment of a planet map, a 2D or a 3D map.
String collections (1Map_texts.amb, 2Map_texts.amb, 3Map_texts.amb, NPC_texts.amb, Object_texts.amb, Party_texts.amb)	Each entry contains a list of strings. There are some commands to alter appearance and display context-specific data:
	"	Starts or ends a passage of spoken text (displayed white)
	^	Paragraph
	~RUN1~	Starts rune-written part
	~NORM~	Ends rune-written part
	~SELF~	Name of player character
	~LEAD~	Name of selected party leader
	0x00 (hex 0)	End of string

The map texts are displayed at specific events at the maps. Every entry corresponds to a part of a main map (Lyramion, Forest Moon, Desert Moon) or a 2D map or a 3D map. They're divided into three files, probably to avoid disk changes. NPC and party texts represent the conversations, similarly connected to the NPCs/ partymembers found in their files. The object texts are displayed when using items (books, scrolls); they don't seem to be in some particular order.

Place_data
Consists of a part with number data and a string part. The strings are the names of stores, training rooms or inns, each limited to a length of 30 characters. The first part most probably specificates the function of those places (type, picture, price factor at stores, price at trainers etc.) in 32 bytes for each place.

Monster_groups.amb
Contains 100 subfiles for the monster formations. Each has a size of 36 bytes, directly representing the formation. Every short int represents a monster (>0) or an empty field (0).

Char data (Party_char.amb, NPC_char.amb, Monster_char_data.amb)
Every entry contains data to a character or monster, such as class, hitpoints, resistances, references to spells, the inventory and so on. The monsters do have some extra data at the end, most probably describing the frames of their animation in battles.
