The Best Pokemon ROM Hacks with Brand-New Regions
Updated October 15, 2026 · 9 picks
Overview
Remakes and difficulty hacks are great, but there is a special thrill in booting up a Pokemon game and not knowing what is over the next hill. The Pokemon ROM hacks with new regions on this list give you exactly that: new towns, new routes, new gym leaders and, in most cases, a story that has nothing to do with the official games.
Building a region is the hardest thing a hacker can attempt. Every map, every trainer and every line of dialogue has to be made from scratch, which is why these projects often take years and why several of them are still officially in beta. We focused on hacks where the new region is the main event, not a side area, and checked each one's current version and status.
The list mixes polished modern projects with older classics. Some keep official Pokemon and put them somewhere new; others go further and replace the Pokedex with fan-made creatures. For each entry we note the base game you need to patch and what makes the region worth visiting.
The List
1. Pokemon Unbound
Borrius is the benchmark every new region gets compared to. Skeli designed it with deserts, frozen tundra, a dense city and a history that ties into the plot, then filled it with more than 80 side missions. The villains, the Shadow Pokemon threat and the post-game all belong to this world rather than being borrowed from an official game. Version 2.1.1.1 is complete, offers four difficulty settings from Vanilla to Insane, and its 2.1 update added Legends: Arceus content, including Galarian and Hisuian forms. If you play only one hack from this list, start in Borrius.
2. Pokemon Prism
Prism proves you do not need a GBA to build an ambitious region. Koolboyman's Naljo is a dark, industrial place, and you play as the child of Lance, which colours the whole story. The region adds three new types — Gas, Sound and Abnormal — plus mining, smelting and an orphanage storyline, and after the main game you can carry on into Rijon and other areas for up to 20 badges. Its release was famously disrupted by a cease and desist in 2016, but RainbowDevs kept it going; v0.95 is the current playable build.
3. Pokemon Gaia
Gaia's Orbtus is built around archaeology. An ancient civilisation collapsed after a run of earthquakes, and when the tremors return, Professor Redwood pulls you into a mystery of ruined temples and old legends. It is a region that rewards curiosity, with Mega Stones tucked away for players who explore. Spherical Ice's team left it at v3.2 in beta form, but the content that exists is long and well-paced, with Pokemon from Gen 1 to 6 and the Fairy type.
4. Pokemon Glazed
Glazed is the choice if one new region is not enough. You begin in Tunod, a fresh region with its own gyms, then the adventure spills over into a reworked Johto and the Rankor region, with five starters to choose from at the start. It is enormous by GBA standards and leans into an over-the-top story. The original author's final version was 8.6.3; the unofficial 9.1 update fixes many issues and modernises mechanics such as critical hit damage.
5. Pokemon Light Platinum
WesleyFG's Light Platinum was the first new-region hack many players ever touched, and it still holds up. You travel through Zhery and then a second region, Lauren, with Pokemon from the first five generations, every legendary available and a Pokemon World Championship to aim for. A vision of Arceus and the creation trio gives the story a sense of scale. It won Hack of the Year 2012 on PokeCommunity, and a DS remake is in progress.
6. Pokemon Vega
Vega goes one step beyond a new map: the Tohoak region is populated largely by 181 original Pokemon designed by an anonymous Japanese team from 2ch, alongside some species from later generations. It also adds 70 new moves. Dr. Akimbo's English translation made it accessible, and its quality and difficulty curve feel close to an official game. If you want a region that feels genuinely unfamiliar, Vega delivers more than almost any other hack — and its sequels, Altair and Sirius, continue the story.
7. Pokemon Clover
Clover's Fochun region and the Ebin Isles were built by 4chan's /vp/ board, along with all 386 of its fakemon. The result is a strange, funny and frequently offensive parody, so it is not for everyone. Under the jokes, though, sits a carefully built game with a custom soundtrack, a modern battle engine, smart AI that switches Pokemon and reusable TMs. Version 1.3.3 is complete and stable.
8. Pokemon Mega Power
Mega Power's Ivara region comes with a twist: you are not a rookie trainer but a young scientist who has already created Mewtwo, and the plot follows your attempt to make it Mega Evolve without a Mega Stone. The journey later reaches the Lande region and the Sevii Islands. Every Mega Evolution is available, alongside selected Pokemon from Gen 4 to 7. The latest release, Beta 5.77, is complete despite the beta label.
9. Pokemon Dark Rising
Dark Rising's Core Region is a gloomier place than most. Climate disasters, a chosen-one prophecy and a villain known only as V give the story a heavier tone. Pokemon from five regions are available, and gym leaders lean on signature Pokemon you cannot catch yourself, which makes them feel like real bosses. DarkRisingGirl released it in 2012, and it inspired a Kaizo edition and a full sequel. It is a good pick if you want a new region with real tension rather than a cheerful tour.
Final Thoughts
If you have never played a new-region hack, Unbound is the safest first step: it is complete, polished and adjustable in difficulty. Players who want something stranger should try Vega or Prism, while Light Platinum suits anyone who prefers a classic, lighter adventure. Whatever you choose, patch it onto the exact base game listed above and back up your save before applying updates.
