Erasing PNG images.

Hey all, I used libPNG for a program that is supposed to draw a smiley and control its movement through the directional buttons. Everything is working fine, except that the old smileys are not erased. I've tried pspDebugScreenDebug() and one that was like sceClearScreen(), but they just make my FPS seem lower while the old smileys stay in place. I ended up using a black png to go over the old ones, but does anyone know a function to clear the whole screen?

Post your code.

srry, but im not really sure wth ur asking. y cant u just hook ur psp up 2 ur pc and delete the pics???

i only know about lua but the principles hould be the same the clear screen command should clear the screen are you sure sceClearScreen() is the right command
