Exile: an annotated disassembly of the enhanced BBC Micro version

An annotated disassembly reconstructs the enhanced BBC Micro version of Exile, the 1988 Superior Software adventure game, from its binary images, covering the sideways-RAM sample loader, the decryption code and the main game. Technical notes give the address ranges of the sprite plotter, the procedural 256x256 tile landscape generator, the three-list object physics engine, envelope-based sound, NPC mood stimuli and the novella-word copy protection, alongside game-play notes and a list of memory pokes.

Requirements & limits

Scope: Covers the enhanced version, which keeps code, data and sampled sounds in sideways RAM; the standard version and the disk protection and supervisor have separate disassemblies on the same site.
Limits: Created from binary images without access to source code; the author describes it as reasonably complete.
License: The author imposes no copyright restrictions beyond those already present on the game.
