The Cartridge Family Tree

A visual reference map for cartridge parent cases, design influences, eras, and use cases.

Cartridge names get less mysterious once you can see the family resemblance.

Use this as a reference map for parent cases, design influences, commercial eras, and the odd little historical detours that explain why a round exists in the first place. Start with lineage if you want the parent-child view, switch to era if you want the timeline, or search for the cartridge that sent you here.

    Cartridge lineage is sometimes debated - some "parent" relationships are case derivations, others are design influences. Dates reflect commercial introduction; wildcats are listed by their factory adoption year where applicable. Dashed lines mark design influence rather than direct case parentage.

      Lineage Note

      Cartridge history is not always as tidy as a family tree wants it to be. Some relationships are direct case derivations. Others are design influences, wildcat histories, or commercial adoption stories that got cleaned up later by factory naming. Dashed lines mark influence rather than a direct parent case.
