You should check out Ultimate Brain Games if you can. It has exactly what you
are wanting to do. This has a couple of screenshots for example faces that can
be created but you really gotta see the creator in action.

Hello,
I was just wondering if it is possible to have the GBA create image files
that could be put with a saved game. I am a true beginner ;_; My Idea is
when a person starts a new game in the game...they will be able to choose
what they look like and have the sprite reflect those choices throughout the
game. I don't know if there is any other way to do this other than having a
whole set of sprites..etc. for each combination. Also the game is an RPGish
game...I know that I should not be doing a more advanced concept before I
become proficient...but I have a great idea and I don't want it to die on
me!!
