Preservation method

Stored bytes.
Visible provenance.

The original cartridge is unchanged. Each preview records its image source, palette and any map used. Named graphics files and image blocks found in the ARM9 executable and overlays are retained in the source download. Unresolved formats, unsupported sprite datablocks and conversion notes remain in the manifest.

The NCG, NCL and NSC decoder was checked against Xzonn’s first-hand format research. PNG conversion preserves pixel positions and RGB555 colors; transparent palette entries are represented with alpha. No generated or substitute game artwork is used.

Original game, images and characters belong to Nintendo and their respective creators.
