+***Pre-1.9 Keys***
+
+The following keys were valid prior to 1.9 and were deprecated as of 1.9, since they were included in the keys `kS29`-`kS33`. Each color, instead of using one key, used 3 keys to represent Red, Green, and Blue values, respectively. In 1.7 and 1.8, the game used a fourth key to determine if a color channel used a player color, and which player color it would use.

 ### Start Pos Object
 The Start Pos object has the same special properties the level start object has, with a few not working. `kA9` must be set to `1` in the case that the object is indeed a Start Pos.
