Pokémon SoulSilver Improved Gym Leader Teams is a fan-made modification of Pokémon SoulSilver for the Nintendo DS. This hack enhances the teams of Johto Gym Leaders and Elite Four members by incorporating more region-specific Pokémon, while also adding a slight modification to Red's team. The adjustment includes mild level tweaks and an increase in the number of Pokémon per trainer, though post-game encounters remain unchanged.
This is a hack of Pokémon SoulSilver which changes the teams for the Johto Gym Leaders and Elite 4 to give them more Johto Pokémon (or place more emphasis on Kanto Pokémon, for the two Kanto-based Elite 4 Members, Lance notwithstanding), and a slight change to Red, giving him the Espeon he originally had in GSC. There's some mild level tweaks and these trainers generally have at least one more Pokémon. The post-game trainers and rematches, Red aside, have not been touched.
This is not considered a difficulty hack as the intent is NOT to make the games more difficult, just to change up the teams a bit.
If you're having trouble getting the romhack to run properly, the DSPRE suggested version should work.
