Pokemon JetBlack is an NDS ROM Hack by EstrethAthema based on Pokemon Black in English. And it is now available to download. It was last updated on September 1, 2025.
Description
Pokemon JetBlack is an enhancement hack designed to improve the experience of the original Gen 5 games while staying true to their spirit. The main campaign remains faithful to the Unova Dex, only Gen 5 Pokémon are available during your journey, but with expanded wild encounters, updated trainer rosters, and subtle tweaks to keep the adventure fresh. Built with a love for Unova, JetBlack aims to refine and enhance without losing what made the originals special.
Features
- Expanded wild encounters for more diverse team-building, with many Pokémon available earlier in the game.
- Updated stats and learnsets, including Egg Moves, B2W2 tutor moves, and a few new options (ex: Earth Power Serperior, Slack Off Emboar, Shell Smash Samurott).
- Hidden Abilities added to several Pokémon without changing their original types.
- New and rebalanced moves from later generations, including Liquidation, Mystical Fire, Lumina Crash, and an improved Rock Wrecker.
- Revamped trainer rosters with added variety. Gym Leaders and bosses use new strategies, items, and Pokémon.
- 17 new battles: 4 during the main story (rewarding useful items) and 13 post-game, including Gym Leader rematches and the Striaton Brothers.
- Two new explorable areas: Dreamyard Basement and Challenger’s Cave, now scaled down with trainers and items.
- Trade evolutions removed for accessibility.
- HMs are unlearnable (v1.2).
- Keldeo, Meloetta, and Genesect are now encounterable in the post-game (v1.3), with Liberty Garden accessible using the Liberty Pass.
- Berry Bundle Sellers added across Unova (v1.4), selling restoration, pinch, resist, and exotic berries.
- Every Pokémon is now obtainable within JetBlack (v1.5).
- Complete documentation provided, including Pokémon changes, encounters, and trainer rosters.

Dawwggg they really needa make the shiny odds better for starters in these. I reset like a hundred times and no shiny starter. How do you mfs shiny hunt these cute lil bastards bruh???????? Runnin outta patience over here. It should be a 1 in 50 chance at the highest bc you gotta reset for natures n ivs too. AND YOU CAN’T EVEN CHECK YOUR NATURE UNTIL YOU GO THRU ALL THIS EXTRA TALKIN ON TOP OF 2 BATTLES
I thought they wanted to make it more like Black White 2? Couldn’t yall add a feature to let you check your Pokémon before initiatin the battles? I’m never gonna have a legit shiny starter in my entire life
