thanks justin, Dark Serge may not even be on Disc 2; certain enemies are disc exclusive. By association, this would necessitate a Dark Serge hack, since a Gameshark code cannot put in models that don't exist. However, my memory may not serve in this case.
D7 for Dario and DD for Flea check out as far as the order in which enemies would be stored on the first game CD at least. justin, do D7 and DD produce Dario and Flea respectively on Disc 1 as well?
