v3.3.7 of Gen 9 Pack applied to the Aug. 24th build of Feral F - Sevii Islands.
- Previous generation Pokémon were also readded.
- Gen 9 abilities, items, TMs, and moves were added.
- PokeGirls (and their variants) are still in the game and functional.

Nothing was changed in regards to spawns, Trainer battles, story, etc.

You can add in new Pokémon on existing maps via the PBS/encounters.txt (to add/change grass/surf/fishing encounters) and new Pokémon to existing Trainer battles (not new battles - you need RPG Maker XP for that) in the PBS/trainers.txt.
