 The first thing to use the display system is to init the console with the background that will handle the text, and of course, the font to use.  
 We will see later how to customize the font. PVSneslib is shipped with a default font named pvsneslibfont.bmp. Just take a look at it to know how characters are.

+You can also change the text graphics and map VRAM address by using the functions:
+```

+    consoleSetTextVramAdr(background map address);
+    consoleSetTextOffset(offset of text in background map address);

 so, you can use **if (pad0 & KEY_A)** to know if button A is pressed or **if (pad0 & (KEY_A | KEY_X))** to know if button A **or** button X are pressed. Notice that we used the **|** operator to add different buttons, not the **&** operator, this is because **|** is like the adding operation.
