I don't know, maybe I'm missing something. The "error" is a warning, not an error and things will load correctly unless P5 specific features have been used. P3dOExplorer will quickly and easily convert the png's to rsr's, it's free, and it is a worthwhile utility program to have. An even bigger pain is converting the JPG's to BUM files, but it isn't all that big a deal. The only reason one could not buy these products and use them is because... Well, there are no good reasons. So, what's the big deal?
