Dig Dug: translating arcade routines and modeling triple-Z80 hardware

Dig Dug translates routines from the 1982 arcade game's Rev 2 ROMs into Rust and models its three Z80 processors and Namco I/O, video and audio hardware. It includes a disassembler, memory-map report, native windowed port and differential checks against a separate Z80 interpreter. The author states that translation coverage and full hardware equivalence remain incomplete.

How evidence classes are assigned

Requirements & limits

Prerequisites: Stable Rust and a user-owned Dig Dug Rev 2 arcade ROM set are needed for gameplay.
Testing evidence: ROM-dependent regressions require the original ROMs; ordinary tests use synthetic data.
Limits: Timing, custom I/O and gameplay coverage remain incomplete.
