18<h2>Description</h2>
19
20<p>This program tests simultaneous use of preloaded and cached texture. Textured cubes are displayed on the screen. Out of the 16 textures used in this example some are preloaded and others use caches. You can set up to seven preloaded textures up (this program prepares only 8 regions shared for preloading and caching).</p>

126<h2>Operation Method</h2>
127
128<p>START exits the demo.</p>
129
130<p>The L and R Button changes the number of preloaded textures (0-7).<br>If the number is n, textures with numbers that are less than n are preloaded.</p>
131
132<p>The X and Y Buttons change the number of layers drawn.<br>Drawing many layers to check the difference in performance may be useful.</p>
