The Sevii Islands were a location in FireRed and LeafGreen. They were mostly for post-game content after you defeated the Elite Four. That’s where Pokemon Sevii comes in when it is a ROM hack using Pokemon FireRed as its base.
The initial location is the Sevii Islands, where you do the usual things until you stumble on Kanto. It’s an interesting ROM hack setting you on the different islands of Sevii. Explore and enjoy your new adventure although be warned the game has some glitches.

Story
You’re a 15-year-old living on One Island (which is one of the Sevii Islands) just going about your day until Celio asks you to do an errand. You get an Eevee as a form of protection.
When you get back to Celio, you discover that someone has stolen his other Eevee, and that means that you have to uncover the mysteries of what is going on. You’ll be encountering members of Team Delta and more along your adventure.
Features
The game has included some original music to play in the game. You get to explore the Sevii Islands first before going to Kanto, giving you a total of 16 Gym Leaders to conquer.
The graphics as well have been altered to look like some of the NDS games. Nearly 800 Pokemon to capture from multiple Generations as well as updated stats, types, and more. The game is expected to have more updates in the future, as well as fixing some of the bugs.
