Extraction: decode the Z80 snapshot's 48K memory pages, read original 32-byte
sprites as four 8x8 UDGs, and read four frame pointers, colour attributes and
50Hz animation delays directly from each creature's object record. 5301 sprite
bytes were also checked against the disassembly's DEFB data. Creature timing
uses the game data rather than the GIF preview timings in annotations.
Effects use original bitmap frames with browser-adapted timing for readability.
The ordinary wizard designs are static in the original game.

Wizard Arena's modern artwork is original generated artwork. Its simplified
combat/spell rules do not claim to reproduce the full original Chaos engine.
