Some challenge

Pokémon Enduring Emerald is a hack that replaces the Hoenn Pokémon in the wild and in trainer battles with most of the Pokémon from Kanto and some from Johto. The regional Pokédex now includes 175 Pokémon, all of which, except for the starters, should be catchable. You can choose Bulbasaur, Charmander, or Squirtle as your starter Pokémon. Instead of using your starter to save Professor Birch from a Zigzagoon, you’ll be saving him from a Nidoran. This hack aims to blend elements of Emerald’s past with aspects of its future to create a new experience that still feels familiar to fans of the Gen 3 games. I used Pret’s pokeemerald decomp as a base and have thoroughly tested the game with my additions in multiple emulators to ensure there are no major bugs. Note: This isn’t intended to be a difficulty hack, but the bosses will be slightly tougher to balance the easier XP gain. The Pokémon in the first four gyms will be one level higher than before, while those in the last four gyms, the Elite Four, and the Champion will be two levels higher. Despite these adjustments, you shouldn’t encounter any Pokémon above level 60 before the postgame.

FIELD EVIDENCE

3 CAPTURES

OFFICIAL INTEL

  • A National Dex featuring 175 Pokémon from Kanto and some from Johto.
  • Generation 1 starters: Bulbasaur, Charmander, and Squirtle.
  • All Hoenn Pokémon have been replaced with Kanto and Johto Pokémon.
  • The Zigzagoon you save Professor Birch from has been replaced with a Nidoran.

MISSION REPORT: POKEMON ENDURING EMERALD

Explorer: DexHunter Ace (LVL. 100)
Expedition Duration: ~28 hours
Dex Completion at Filing: 171/175 (97.7%)
Status: Post-game sweep in progress. Those last four slots are haunting me.

INITIAL ASSESSMENT — WHAT IS THIS REGION?

Okay. Okay okay okay. Picture this: you know Hoenn. You've walked every blade of grass in Hoenn. You've memorized the tile map of Route 119 in your sleep. Now imagine someone reached into Hoenn's ecosystem and ripped out every native species, then repopulated the entire region with Kanto and Johto fauna. That's Enduring Emerald. Same geography, completely different biology. It's like walking through your childhood home and finding someone replaced all the furniture with stuff from your grandparents' house. Disorienting? A little. Fascinating? Absolutely.

The regional Pokédex clocks in at 175 species. That's modest — tiny, even, compared to the 400+ behemoths I usually tackle — but here's the thing: modest means achievable. Modest means I can see the finish line. And the documentation claims every single one (minus starters, which you pick at the beginning) is catchable in a single save file. Living Dex is possible without cheats. My hands were shaking when I read that. No trade evolution nonsense gating me out? No mythical locked behind a dead Wonder Card server from 2007? Just catch them. In the wild. Like Arceus intended.

THE LANDSCAPE — HOENN, RESKINNED FROM THE INSIDE OUT

Timestamp: Hour 1 — Littleroot Town

Professor Birch is being chased by a Nidoran instead of a Zigzagoon. It's a small thing. It's also the exact moment I knew this expedition was going to be different. Bulbasaur, Charmander, Squirtle — the holy trinity — waiting in that bag. I grabbed Squirtle because I'm a completionist, not a monster, and Squirtle has the best early coverage for surfing utility later.

The visual landscape is unchanged — this is still Hoenn's terrain, Hoenn's map, Hoenn's architecture. But every route, every cave, every patch of tall grass has been re-stocked. Route 101 has Pidgey and Rattata instead of Wurmple and Poochyena. Granite Cave is crawling with Geodude and Machop and Zubat — classic spelunking lineup. It's like a Kanto safari through Hoenn's geography, and I was documenting encounter tables like a madman from minute one.

QUALITY OF LIFE — THE STUFF THAT MATTERS

Let me get to the part that made me lose my mind (in a good way). The QoL features in this region are stacked for completionists:

  • Any Pokémon can use field moves as long as the corresponding HM is in your bag. I nearly wept. No more HM slave taking up a party slot. No more carrying a Zigzagoon — sorry, there are no Zigzagoon here — just for Cut and Surf. My full team of six stayed intact the entire run. This is regional technology that every region should adopt immediately.
  • Exp. Share is a key item. Toggleable. Party-wide. Gained on schedule. This meant I could rotate my entire living dex through my party for evolution purposes without grinding individual species into dust. Efficiency. Beautiful efficiency.
  • XP on catch. You gain experience for capturing Pokémon. This is completionist paradise. Every catch fuels the grind. Every Pokédex entry makes the team stronger. The feedback loop is so tight I could feel dopamine hitting my brain every time that ball clicked shut.
  • Poison doesn't damage you in the overworld. Small change, massive impact for early routes where Nidoran and Weedle are spreading toxins everywhere. No more frantic dashes to Pokémon Centers.
  • You can run indoors. Listen. LISTEN. Do you know how many hours of my life I've spent walking at half speed through buildings? Do you have any idea? This feature alone adds years to my lifespan.
  • Poké Mart inventory is badge-gated, not story-gated. Meaning I could buy Great Balls the second I had enough badges, without needing to trigger some specific cutscene first. Streamlined. Clean.

Best QoL: Infinite Repel system. Wait — let me clarify. This region doesn't explicitly have an infinite repel toggle, but the combination of XP-on-catch and indoor running and no overworld poison means traversal is so smooth it feels like infinite repels. When I actually needed to hunt specific encounters, I was using Repel stacks strategically, and the Mart access made restocking trivial.

THE DEX — 175 SLOTS, 175 OBSESSIONS

Timestamp: Hour 14 — 62.3% completion

Here's where my spreadsheet came out. The 175 Pokémon are drawn from Gen 1 and a handful of Gen 2, and they're distributed across Hoenn's routes, caves, and water routes with reasonable logic. The encounter tables felt thoughtful — you're not finding Dragonite on Route 102. The progression mirrors the original games' power curve: weaker species early, stronger species in later routes and Victory Road.

Notable finds:

  • The Weather Institute event gives you Porygon2 instead of Castform. This is huge for dex purposes because Porygon2 is traditionally a trade evolution nightmare. Here? Handed to you. The researchers in this region understand my pain.
  • Eevee and its evolutions are available, though I had to hunt specific stone locations. Standard procedure.
  • Johto additions include species like Heracross, Scizor, and Tyranitar's line — all catchable in the wild or through evolution. No trade cables required for any of them as far as I could confirm.
FIELD NOTE: I could not confirm whether a Link Cable item is available in this region's Department Store or elsewhere. Trade evolutions like Alakazam, Machamp, Golem, and Gengar — I need to verify if they're obtainable through an alternative method or if they're simply placed in the wild. My 171/175 count may be stuck on exactly these species. If anyone has intel on trade evolution handling, report to HQ immediately.

That said — 175 is a small enough number that the hunt never felt padded. No filler. No "why is this here" moments. Every species had a logical placement. I was checking off entries at a satisfying clip, and the XP-on-catch system meant my team was always battle-ready for the next route.

THREAT LEVEL — BOSSES HIT HARDER THAN EXPECTED

Timestamp: Hour 8 — Badge 5

The intelligence briefing said this wasn't a difficulty hack, and that's accurate — but don't sleepwalk through gym battles. Hostile entities are 1-2 levels above standard Emerald, and that sounds trivial until Norman's Snorlax is tanking hits you expected to one-shot. The Elite Four and Champion field teams 2 levels above baseline, and with the Kanto/Johto roster, the type matchups are different from what your muscle memory expects.

No trainer above Level 60 before post-game. That's the ceiling, and the expedition confirmed it. The party-wide Exp. Share keeps you competitive without excessive grinding, so the difficulty felt balanced — challenging enough to require strategy, never punishing enough to halt progress. Threat level: Moderate. Veterans will push through cleanly. Newcomers might lose a few rounds to the later gyms.

POST-GAME ASSESSMENT

Here's where I have to be honest. Post-game is... Emerald's post-game. Battle Frontier is present — it's the original Battle Frontier, untouched, magnificent, still the gold standard. Post-game is massive. Battle Frontier included. That sentence alone justifies hours of additional expedition time. But the post-game specific to this hack — new areas, new events, new legendary encounters — is limited. You're mopping up dex entries you missed, battling through the Frontier, and that's largely it.

For a 175-dex hack, that's... fine? The scope is intentionally modest. This isn't trying to be Unbound with its 60-hour post-game saga. It's Emerald with a Kanto transplant. Expectations calibrated accordingly.

ANOMALY LOG

No major anomalies detected. The decomp base (pokeemerald) is stable, and the creator clearly tested across multiple emulators as stated. I encountered zero crashes, zero softlocks, zero glitch cities. Map transitions clean. Battle engine stable. Text displays correctly. This region is polished for its scope.

One minor note: some NPC dialogue still references Hoenn-native species that no longer exist in the region. A trainer talks about their beloved Zigzagoon when there are no Zigzagoon within 500 miles. It's not game-breaking — more like finding an old road sign that hasn't been updated. Cosmetic anomaly only.

THE NUMBERS — BECAUSE I ALWAYS GIVE THE NUMBERS

  • Dex Completion: 171/175 (97.7%) — those last 4 are likely trade evos I need to investigate further
  • Play Time: ~28 hours for near-complete dex + full story + initial Battle Frontier run
  • Gym Badges: 8/8
  • Elite Four: Cleared
  • Champion: Defeated
  • Shinies Found: 1 (a Tentacool on Route 124 — yes I kept it, yes it's in the PC, yes I screamed)
  • Estimated 100% Time: ~32 hours if trade evo methods are confirmed accessible
Missable event warning! I did NOT encounter any permanently missable Pokémon during this expedition. The Weather Institute Porygon2 is the only event-triggered species I identified, and it appears to remain available even after the main story event. However, save before entering the cave — specifically Granite Cave and Victory Road — if you want to ensure you catch everything on your first pass. Some species have low encounter rates in those locations.

FINAL FIELD ASSESSMENT

Enduring Emerald is a clean, focused expedition. It knows exactly what it is: Emerald's world, Kanto's Pokémon, modern QoL. It doesn't try to reinvent the wheel. It doesn't add Mega Evolutions or a new evil team or 400 new routes. What it does do is provide a nostalgic, completable, stable journey through a familiar landscape with a fresh encounter list and enough quality-of-life features to make the completionist grind genuinely enjoyable.

Is it best-in-class? No. The scope is too modest for that — 175 Pokémon, minimal new content beyond the species swap, uncertain trade evolution handling. But for what it sets out to do? It delivers. My spreadsheet is nearly full. My dex is nearly done. And I didn't have to cheat, exploit, or beg a friend with a second GBA to get there.

That's a win in my book. A modest, clean, satisfying win.
