Detailed Description

Metasprite item structure (PVSnesLib compatible).

Each item represents one hardware sprite within a metasprite. Uses 8-byte alignment for efficient access.

Tile units (tooling-facing contract)

tile is in 8x8 OAM character-name units relative to the base tile, for the sprite sheet as it sits in VRAM. It is NOT a block index: a 16x16 sub-sprite one block to the right of another is +2 (two 8x8 columns), and moving one block row down adds the sheet's row stride (16 names for a 128px-wide sheet). gfx4snes -T emits these names directly (fixed in issue #100); editors composing their own sheet (Cooper) compute them from their own geometry.
