And I'm not talking about just the portraits, but also the little face icons for the selection screen (the tiny face icons for the highlight boxes, not the large picture of the character). Those need to be custom made too, since all the screenpacks are different and use different styles.
What's nice about downloading a full game (compiled, or "true" full game) is that all of this is done already. All of the icons & portraits are there. And it has a nice professional feel to it. The stages & music are there as well.
