+### Using SDL2 ttf
+
+![](images/sdl2_ttf.png?raw=true)
+
+This is a simple program to use the SDL2_mixer library. Click on details below to see the code and how to build it.

+<b>CMakeLists.txt</b>:

+</pre>
+
+Building can be done with:
+
+<pre>
+mkdir build && cd build
+psp-cmake ..
+make
+</pre>
+
+<p>This will result in an EBOOT.PBP file in the build directory. Put it in a directory in ms0:/PSP/GAME/ and you need a font file to test the program, download it from <a href="/resources/Pacifico.ttf">here</a>. Put it in a directory same as EBOOT.PBP and the PSP can run it.</p>
