What was checked

This development milestone is documented by local Git commit 90ace2f, recorded on October 12, 2026. This retrospective does not add a new verification claim or an archived playable release.

What remains

This was an intermediate development milestone. The current native reconstruction remains incomplete; links on this page open the current build rather than an archived copy of version0.2.0.

The requested free Matchbox guide is an identified enhancement in the recreation. It does not change the ROM used by the original-game player.

The next published update

Each new native release will have its own dated entry here, alongside the playable update. Earlier entries remain as a record of what was available at the time.
