i made it to work and thats what i did (posting here for future reference of ppl like me):
put the Wolf3D in root of G6, then DLDI the wolf3d-shareware.nds and put it in your NDS folder, that way it works.
and I must say that it worked VERY GOOD, one of best ports i ever seen in my life (performance wise), but less than lack of full version, i felt the lack of music, i used to have the mp3 of menu song of wolf3d on my mp3 player.
REALLY WOW to this guy.
