AMBERDEV data

The AMBERDEV.UDO file contains an assortment of data (and possibly executable code?). Some known bits of interest below. The start offsets are approximate and may vary across releases of the game; in particular, they vary between the English and German versions.

Start offset Description Format
21614 Glyph mapping 224 bytes for chars 0x20 to 0xff
2170b String Fragment Table Described for Compressed Text
31a46 Background song names 0-terminated string, terminated by another 0
31eda Combat Palette: template A palette used in combat with three "holes" (colours that are left black)
31efa Combat Palette: variants List of colour triplets to fill the "holes" in the combat palette template
33d70 (approx.) Graphics 16x16, details tbd
473a4 Sky gradients Palette gradients for in-city sky day/night cycle
4ac0a Spell names individual u16 words of Compressed Text
4cdc0 Songs, starting with "City Walk" Background Music

Finding the offsets

Below are some strategies for finding the correct offsets:

  • String Fragment Table: Start of the first occurrence of "HUMAN" or "MENSCH", minus one byte.
  • Songs: All occurrences of COSO
  • Spell Names: Immediately after the first occurrence of 00 00 00 00 01 62
  • Sky Gradients: 0x3866 bytes before the spell name table
  • Combat Palette template: 0x5e5 bytes after the first occurrence of CODETXT.AMB
  • Combat Palette variants: 0x20 bytes after the Combat Palette template
