SDSME is a map editing tool for DPPtHGSSBWB2W2 as well as an alternative to PPRE for some things such as trainer Pokémon and wild data. Unlike PPRE the wild Pokémon areas aren't named directly and you must cross reference IDs with the maps listed on the main screen to find the correct area. Trainers are listed normally, however. I can't comment much on SDSME as I haven't used it and I definitely haven't tried the map editing parts. Tips should be available in any threads about it, though development of SDSME has since been discontinued.
