Did you put the file in the folder?
I always forget to do that, and i solve it by making sure if its there or not. Check |

Probably because you have an endless loop that never swaps draw buffers. |

make sure when you call the function you have:
sceDisplayWaitVblankStart();
flipScreen(); |

| You need to draw the image, then print the text. What you are doing now is not the proper way to use a background. What you need to do is load your image, then start a game/display loop. In the loop you process whatever needs to be processed, then draw whatever needs to be drawn in the order it needs to be drawn (lowest to highest). Then swap your buffers (i.e., call flipScreen()). |
