About Pokemon Moon Black 2
New rivals, Gym Leaders, an Elite Four, and a Champion reshape the Unova challenge in Pokémon Moon Black 2. JrFort and Aster's NDS beta 4.2.3 hack of Black 2 brings Pokémon from Unova, Kalos, Alola, and Galar together with regional forms from Unova and Alola. Mega Evolution works outside battle, while the Fairy type and its updated chart change matchups. New items, moves, events, and a harder difficulty round out the journey. A new Pokémon World Tournament brings in Trainers from every region.

A Black 2 rework that casts Sun or Moon as an Alolan visitor to Unova, with changed trainers, encounters and post-game battles. It is a good fit for players who want that theme on the original Unova route, but its current README still warns of a Hall of Fame problem with pure Fairy-types.
Base ROM: Pokemon - Black Version 2 (USA, Europe) (NDSi Enhanced).
Before you patch
- Use the exact base ROM:
Pokemon - Black Version 2 (USA, Europe) (NDSi Enhanced). The release README identifies that file as the required original game. - Get the creator-linked ZIP. It contains an xdelta patch rather than a pre-patched ROM, plus its README, change log and Wild Pokémon List PDF.
- Patch with an xdelta-compatible tool. The README links Xdelta UI, MultiPatch and a browser-based xdelta patcher.
- Plan around the Hall of Fame. The current README says pure Fairy-types cannot clear it; leave them out of the Elite Four and Champion party.
Who it’s for
This is for players who want Black 2’s Unova progression reframed around Sun or Moon arriving from Alola. The official thread describes a story that starts after the Alola League and has the player work toward defeating the Unova Champion; it also documents post-game battles and rematches.
The official release is still labelled Beta, despite the thread calling the 2020 build “Completed - Beta 4.” Treat the post-game as added battle content, not as evidence of a separately documented, fully completed post-game story.

Pokemon Moon Black 2: common questions
- Which base ROM does Moon Black 2 need?
- The current release README names Pokemon - Black Version 2 (USA, Europe) (NDSi Enhanced). Use that clean base, rather than Black 2 from another region or revision.
- What is in the official download?
- The creator-linked MEGA ZIP contains an xdelta patch, a README, a change log and a Wild Pokemon List PDF. The README points to Xdelta UI, MultiPatch and a browser-based xdelta patcher.
- What is the latest version?
- Beta v4.2.5, dated 28 March 2026 in the included change log. Its listed change is an adjustment to the ROM image; v4.2.4 added most cries for newly added Pokémon and fixed a Nimbasa City stadium text bug.
- Are there any important known problems?
- Yes. The current README says pure Fairy-type Pokémon cannot pass through the Hall of Fame, so do not take one into the Elite Four and Champion sequence. In DSi Mode, a Wi-Fi-settings error screen may appear at launch; the README says pressing A continues and that it does not erase Wi-Fi data.
