I may be the only stupid one on this forum but this might help. I have put graphics, logos, face packs etc.
Its been listed a few times of how you must place the graphics in which directory, which is fine and you untick something and tick another thing. This all listed in a few posts.
Anyway my point is it took me ages to figure out that every time you add new graphics you must go to the display/sound settings and press confirm for them to load. You can't just load new pictures etc and just play you must confirm in the display settings. This may help some people or I'm an idiot cause it took me a while to figure that out.
This might help a few people!
