well i think he just wants to rip the tiles
here is my methed
you get a tile set of the program you want to put the r/s sprites on
you get visuel boy advance up and load ruby or saphire
and you take screen shots of the parts you want to rip
you find a way to get it on ms paint
you cut out the tiles you want on your tile set
and you past it on the tile set
pretty easey really
i dont know if its the proper way and i think dont think it is legel but im not sure it might cross copyright laws or something
