While working on the disassembling of the Bard's Tale serie (mainly the Amiga version), i came across your forum. Some people may be interested even if most posts concern the 8-bit version of the serie.
FYI, i've stopped this project because there isn't a common engine for the whole serie, losing my interest to port the engine (too much work to merge 4 games engine).
Anyway, i have at least decyphered the animated pictures of the 4 games for the 3 systems :
- Bard's Tale I : Tales of the Unknown (Amiga, Atari)
- Bard's Tale II : The Destiny Knight (Amiga)
- Bard's Tale III : Thief of Fate (Amiga)
- Bard's Tale Construction Set (Amiga, PC VGA)
Again, each version/system uses it's own compression/encryption algorithm.
I have written a tool "Bard's Tale Picture Viewer" to read and play the animated pictures :

You can browse the pictures in gif format on my website too. They have some limitations, so if you want the full animation, you should use the viewer.

You can download the viewer with its C# source code here :
