Computer game software, packaged

1. Scope and Applicability

This PCR covers published computer game software supplied on magnetic or optical physical media as a complete saleable packaged product. The foreground boundary begins with accepted software source/build inputs and purchased unrecorded media and unit-packaging components, includes the electricity attributable to development/build work, physical-media replication, inspection and unit packaging, and ends with the packaged product at the publisher's distribution gate.

The product identity follows CPC 3.0 code 47822. Computer game cartridges designed for a specific console, software delivered only by download, and online game services are outside this PCR. Downstream distribution, gameplay electricity and hardware, maintenance, account services and end-of-life are excluded from the default cradle-to-gate dataset and require a separately declared boundary expansion.

The declared media route must be optical or magnetic. Only components and reject streams that actually occur in the modeled product and batch are included.

Development hardware materiality and dataset-added atomic exchanges. Complete protocol cp_development_hardware_materiality for every site, cloud allocation and test environment within the declared release boundary. For each material server, desktop workstation, portable computer, storage device, network device, test console or other test device, add a separate product-input exchange using the actual Tiangong device identity, its own flow property and supplier-dataset reference unit. Allocate each device exchange by its documented time share and reserved-resource share. Do not combine different devices under a selected flow such as “development hardware.” If a device is excluded, retain its identity, screening result, declared cut-off, quantitative basis and approval.

Waste flows

None required by this PCR. Record any specific waste that actually crosses the process boundary as a separate atomic exchange.

Elementary flows

None prescribed. Direct elementary exchanges must be measured and added as individual flows when they occur; upstream electricity emissions remain in the linked electricity dataset.

Outputs

Product flows

No separately exchanged product output is prescribed. The release build is an internal result transferred to media_replication_packaging; its shared burdens are allocated to the final packaged reference product.
