Detailed Description

Which graphics sheets back sprite OAM tiles 0x000-0x1FF.

The game fills eight 64-tile slots: slots 0-3 hold the static sprite sheets (0x73, 0x74 on the overworld or 0x7D in dungeons, 0x79, 0x7A), matching OverworldMap::LoadSpritesBlocksets and Room::LoadRoomGraphics; slots 4-7 hold the spriteset's four values + 0x73. OAM tiles with the name-table bit set (0x100-0x1FF) therefore come from the spriteset.
