Pokémon Amethyst
A brand-new region on the FireRed engine, built to feel like an official GBA game: eight gyms themed on battle mechanics rather than types, every Pokémon from the first eight generations, and Gigantamax forms reborn as Megas.
More about the game
Pokémon Amethyst is duck_caper's first ROM hack, a new region called Kulure built on FireRed with the Complete FireRed Upgrade. It sets out to feel like a lost GBA entry rather than a remix: a full story with Team Pluto, a rival, eight gyms and a League, followed by a substantial postgame. The gyms specialise in battle mechanics — terrain, status, weather, stat changes, abilities, held items, double battles — instead of types, which is left to a house of Gym Trainees in Tsarvosa City. Every Pokémon from Generations 1 to 8 is in the game, split across a Standard Pokédex and, from v1.3, a hand-curated Divergent one that swaps out wild Pokémon, trainer teams, trades and legendaries. Mega Evolution and Z-Moves are in, with every Gigantamax form converted into a new Mega. The difficulty, level-cap style, starter generation and quality-of-life kit are all chosen when a save begins.
What's different, point by point
- A new region, Kulure, with a complete story, Team Pluto, a rival who evolves their Eevee based on your starter, eight gyms and an Elite Four
- Gyms built around battle mechanics — terrain, status, weather, momentum moves, stat changes, abilities, held items and double battles — with type specialists as separate Gym Trainees
- Every Pokémon from Generations 1 to 8, with the Divergent Species mode (v1.3) replacing dex entries 1 to 300 with a second hand-curated list
- Standard, Hard and Extra Hard difficulty, and soft or hard level caps, chosen at the start and adjustable from the options menu
- Mega Evolution and Z-Moves; every Gigantamax form becomes a new Mega with its own type, ability and stats
- PokéChips, a second currency dropped by wild Pokémon and spent at move tutors, a crafting crusher, ball swapping and apricorn ball shops
- DexNav, Portable PC, PokéVial, Infinite Repel, reusable TMs, HMs usable without teaching, a Gen 6 style Exp. Share and a move relearner for egg moves
- Frostbite replaces freeze, dark grass gives wild double battles, critical captures scale with your Pokédex, and swarms bring regional forms to one route a day
- Game Modifiers unlocked in the postgame or by code: randomisers, inverse battles, scaled levels, shiny mode and more
- A postgame Ultra Episode with the Ultra Beasts, gym leader and Elite Four rematches, title defence, new legendaries and a Professor's Conservatory

What this guide covers
Every guide here is built from the game's own documentation. Where a ROM hack changed something but never published the numbers, this says so rather than quietly filling the gap with the original game's — which would be worse than leaving it out.
| Section | Source | |
|---|---|---|
| Wild Pokémon by area | Not published by the creator | The creator has not published wild encounter tables. Only the encounters the Feature List names — daily swarms, roamers, fixed legendaries, gifts and in-game trades — are listed, and nothing is filled in from FireRed. Ask in the Amethyst Discord Amethyst is built on FireRed / LeafGreen; the FireRed / LeafGreen guide has the original game's wild encounters. |
| Encounter rates | Not published by the creator | Not published. The swarm and roamer odds in the notes are the only rates the creator gives. Ask in the Amethyst Discord Amethyst is built on FireRed / LeafGreen; the FireRed / LeafGreen guide has the original game's encounter rates. |
| Wild levels | Not published by the creator | Not published, apart from the levels of gift Pokémon. Ask in the Amethyst Discord Amethyst is built on FireRed / LeafGreen; the FireRed / LeafGreen guide has the original game's wild levels. |
| Stats, abilities and movesets | Not published by the creator | Only the 30 new Mega forms are documented (types, ability, stats). For everything else the creator states that stats, types and level-up moves match the official Generation 8 games, but publishes no tables, so no species pages are built from them. Ask in the Amethyst Discord Amethyst is built on FireRed / LeafGreen; the FireRed / LeafGreen guide has the original game's stats, abilities and movesets. |
| TM and HM compatibility | From the game itself | All 100 TMs and 6 HMs, from the creator's list. Per-species compatibility is custom to the game and not published. |
| Where TMs are found | From the game itself | Every machine's location and field requirement, in the creator's words. |
| Trainer and boss teams | Not published by the creator | Trainer rosters are not published. The boss order and each boss's ace level come from the level-cap table and are shown on the stage pages. Ask in the Amethyst Discord Amethyst is built on FireRed / LeafGreen; the FireRed / LeafGreen guide has the original game's trainer teams. |

Reading the tables
What Is Here And What Is Notduck_caper publishes a Feature List for Amethyst, and this guide is built only from that: every TM and HM with its location, the level-cap tables, the HM badge gates, in-game trades, gift Pokémon, swarms, roamers, move tutors, item locations and the new Mega forms. The creator has not published base stats or learnsets for ordinary species, wild encounter tables with rates and levels, or trainer rosters, so those sections say so rather than being filled in from FireRed or from memory. The Pokédex data Hackdex links to is a third-party ROM-extraction site, which this site does not use.
Level CapsSoft caps (default) go by badge count: 15 with none, 25 with one, then 35, 45, 55, 65, 75, 85 and 100 with all eight. Hard caps follow the next boss's ace, from 13 at the start through 15 after Terrence, 17 after Irene, 20 after Casey, 26 after Stella, 33 after Raine, 37 after Chance, 41 after Ronald, 47 after Casey's gym, 50 after Abby, 58 after Kurtis, 63 after Alistair, 66 after Dennis and Dee, 74 after the Victory Road rival, and 100 as champion. On the Hard and Extra Hard difficulties bosses are a level or two higher, so the hard caps become 13, 16, 17, 21, 27, 34, 39, 42, 48, 52, 58, 64, 68, 75 and 100. The Extra Hard cap option is two below the hard cap except for the last. The full table is under "What changed", and each stage page repeats the caps in force there.
EncountersThe wild tables are not published, so the route pages list only what the documentation places: the daily swarm species, roamers, fixed legendaries, gift Pokémon and in-game trades. Levels and rates for these are shown only where the document gives them. Fossils are ordinary wild Pokémon here rather than revived.
Pokémon ListStandard and Divergent are separate Pokémon lists chosen at the start (v1.3). Swarms, trades, Mega Stones and some evolution items differ between them and are tagged with the list they belong to; gifts are the same in both. A Game Modifier unlocked by finishing Divergent mode lets a save switch between the two.
TmsTMs are infinite and appear as yellow Poké Balls in the overworld. The locations are the creator's own words, with the field move or badge needed in brackets; the stage shown is the later of the area and that requirement. TM and tutor compatibility is custom to this game and not published, so no per-species TM lists are shown.
MegasThe %d Mega forms listed under Pokémon are the ones this game invents from Gigantamax forms; their stats, types and abilities are the creator's published numbers. Their learnsets are the base species' official ones and are not repeated here. All official Megas are in the game unchanged.
VersionsThis guide follows v1.3.0 (11 July 2026), the current Hackdex release. The creator's document also describes v1.4 additions — the Battle Frontier, Hisuian forms, new swarm species and some items — which are left out until that version ships.
Move StatsMove type, category, power and accuracy shown on the TM and tutor pages are the official Sword and Shield values, which is what the CFRU engine implements; the creator has not published a separate move list.
