convert sprites with grit but don't remove them after make

[Tomdev]

ok I was editing a example makefile(from the nds sprite examples) to convert the png files into sprites, that were binary files(not .s files) and that they wouldn't be removed after i build the program. also i want that they will not be included in the rom, because i load the files from fat. I already looked at Cearns site, especially to grit-converting as a seperate process, but that makefile, i just don't know how to edit it to my needs(I always mess makefiles up ) so can somebody give me an example how to this?
