       A tile set is an array of (up to) 512 tile definitions and each tile definition is 128 bytes.  The tile definition
-      is comprised of four, 32-byte tiles; a normal tile, its mask, a horizontally flipped versio of the tile and its mask.
+      is comprised of four, 32-byte tiles; a normal tile, its mask, a horizontally flipped version of the tile and its mask.
       The first 128 bytes of a tileset must be set to zero.

+    <p>
+      The <em>start</em> and <em>finish</em> parameters define a subset of tiles to be copied into the GTE memory
+      buffer. This is most commonly used to load a small number of tiles to avoid needing to store a full set of 512
+      tiles that are mostly unushed.  For eample, loading in 16 tiles can be performed as <tt>GTELoadTileSet(0, 17, tilePtr)</tt>.
+    </p>
+    <p>
+      This function can also be used to swap out subsets of tiles on the fly.  Any tiles that are replaced which may
+      be on-screen are not automatically refreshed.
