@ -217,6 +217,11 @@ The first thing you'll notice when you run this code is that the speed
of 360x480 256-color mode is pretty good, especially considering that
most of the program is im-plemented in C.

![](images/i.jpg) *Drawing in 360x480 256-color mode can sometimes actually be faster than in the 16-color modes, because the byte-per-pixel display memory organization of 256-color mode eliminates the need to read display memory before writing to it in order to isolate individual pixels coexisting within a single byte. In addition, 360x480 256-color mode is a variant of Mode X, which we'll encounter in detail in Chapter 47, and supports all the high-performance features of Mode X.*
