As part of setting up the Pax Britannia subdomain here, Andrew Owen has published a number of technical details about the ZXodus engine. This post lists some basic features of the engine, and some information about its target platform — the ZX Spectrum +2B — can be found in this post. The engine’s memory use, meanwhile, is discussed in this post.

Oh, and in this post, he goes into detail about how dungeon levels are stored in memory.

He has also published details about characters in the game, including the stats that are used for player characters, attributes that NPC characters will possess. Character classes — both pure classes and cross-spec classes — are discussed in this post.

Some of this information has been released before (e.g. on the Ultima Dragons Facebook page), but it’s nice that there’s now a more organized repository for the data whereat it can be searched out and viewed on a whim.
