Pokémon Elysium

The story

You play a 16-year-old girl from the island of Crysta who dreams of becoming Champion, with the final rounds held on the mysterious island of Elysium. Behind the tournament, a plan more than a century old is coming to fruition. The adventure is split into a prologue, four chapters and an epilogue, with plenty of side quests, and the focus is firmly on the plot rather than on catching every Pokémon.

What's new

• a new region and storyline, a little harder than the official games
• Pokémon, moves and types up to the X and Y era, mostly from the first three generations
• the Fairy type and the physical/special split

Playing it

The hack comes in two parts. After the eighth badge and the first championship rounds, boarding the S.S. Challenger tells you to carry on in Part B with your latest save (some emulators need the save file renamed to match). Each part is applied to its own clean copy of Pokémon FireRed, following the instructions in the creator's PokéCommunity thread.
