please help me

How did you install libpng and where did you get it from?

i followed this intruccions in this page http://code.google.com/p/snes9x-gx/wiki/Compiling
and i get the libpng from here http://sourceforge.net/projects/devkitp ... s/portlibs

sorry i just found out my error
i combined the ppc portlibs with the arm portlibs
