Description

Pokemon Well-Formed Ultra Moon aims to make every Pokemon reasonably viable throughout the game, while providing a fun and challenging experience to the player, alongside various QoL changes and more.

Features

  • New Megas and alternate Formes
  • 81 (and counting) Formes from Generations 8 and 9 (e.g. Hisuian Zoroark), as well as custom formes (such as Crystal Onix and Orrean Feraligatr), have been added to the game, using my Forme Insertion Tool.
  • Custom teams for every NPC
  • Changes to the Stats and Abilities of every Pokemon
  • Numerous moves, learnset, and item changes
  • Changes to game text and dialogue, including “various NPCs no longer assume you are a child”, removal of many of the egregious pauses in the Rotom Dex and Battle Royale dialogues, custom flavor text for every move when used, and more.
  • The vast majority of Pokemon, if not all Pokemon, are in the same general level stats-wise, and each has some unique thing that makes them cool and fun to use.
  • Similarly, most moves excepting the “starting” moves are similarly buffed and diversified.
  • The game is pleasantly difficult, and by taking various optional challenges (not game-enforced, 3DS scripting is nowhere near advanced enough for that), the difficulty can be modulated. 
  • Shops and BP stores have been entirely remade – all Evolution items, Mega Stones, and TMs are available by the end of Ula’Ula, and most of them by midway through the second island, giving the player access to most options relatively quickly.

What if the ROM is encrypted?

If you find a ROM that's encrypted, you need to use the Batch CIA 3DS Decryptor, created by Matif.

The ROM isn't working correctly?

Not all games are fully compatible with Citra. If you do find a game that's not working, try using the latest PabloMK7 Citra fork, the continuation of Citra since its shutdown.
