* [https://www.youtube.com/channel/UCwRqWnW5ZkVaP_lZF7caZ-g Retro Game Mechanics Explained] uploaded multiple YouTube videos (see above) that analyzed sprite decompression in detail, which formed one of the earliest publicly available documentations on this topic.
* Kagamiin discovered that the delta decoding procedure (but not the XOR unpacking procedure) uses pointer arithmetic when moving to the next column, which does ''not'' treat a sprite height of 0 as 256, resulting in a "special" behavior for sprites with height 0.
