OFFICIAL INTEL

  • A brand new region with lots of new maps, events that differ from the original games.
  • Some custom palettes (some ow tiles, ), custom ow sprite, backsprite (for male player only), new town map. (making these is way harder than it seems).
  • Some custom added ASM routines (releasing a pokemon – not using the pc, The IV display on the stat menu).
  • Lots of pokemon available, including all legendary pokemon from gen1 to gen3 which can be obtained with various methods (some before the elite 4, some with certain requirements, some randomly by chance, etc…)
  • New music tracks (mostly battle tracks)
  • A place after the elite 4 where you can battle against one of the 19 NPC’s (the choice of the NPC is random, and every NPC there was previously encountered/the player interacted with the NPC) – called the CK Frontier (although that’s the only feature as of now).

MISSION REPORT: POKEMON NEON BLUE

Explorer: DexHunter Ace (LVL. 100)
Region: Neon Blue Territory
Expedition Duration: 32 hours
Final Pokedex Completion: 94.7%

INITIAL CONTACT

Okay. OKAY. Deep breaths. I just emerged from the Neon Blue region and my hands are still shaking. Not from excitement—from frustration. Let me explain.

First contact with this region was promising. Brand new landmass, completely divorced from standard Kanto geography. The cartographers here went absolutely feral with the map design. Fresh routes, original town layouts, custom visual palettes that made my eyes do a little happy dance. The local technology includes an IV display directly on the stat menu—I nearly cried. Do you know how many hours I've wasted with external calculators? This is civilization.

THE POKEDEX SITUATION

Here's where my brain started doing that thing. You know the thing. The counting thing.

Living Dex is possible without cheats. All Gen 1-3 legendaries are obtainable within the region through various acquisition methods. Some before the Elite Four, some with specific prerequisites, some through—and I quote from my field notes—"random chance encounters." That last part? That's where the cold sweats started.

MISSABLE EVENT WARNING! Several legendary encounters appear to be chance-based with unclear trigger conditions. Save. Constantly. Save before entering ANY suspicious cave, building, or slightly unusual patch of grass. I am not joking.

The Pokemon availability is genuinely impressive for a custom region. Diverse habitats, logical distribution patterns. But the documentation on encounter rates? Non-existent. I spent 6 hours in one route trying to confirm whether a certain spawn was real or if I'd hallucinated it from sleep deprivation.

QUALITY OF LIFE ASSESSMENT

Let's talk QoL because this is where Neon Blue gets... complicated.

The Good:

  • IV display integration—revolutionary for breeding optimization
  • Pokemon release function outside of PC storage—finally, field releases!
  • Custom trainer backsprite (male protagonist only, which is... a choice)
  • New battle music tracks that don't make me want to mute after hour 15

The Missing:

  • No confirmation on Link Cable item availability in shops. I searched every Department Store. Every vendor. Nothing. Trade evolutions remain a mystery wrapped in an enigma wrapped in my mounting anxiety.
  • No infinite Repel system detected. Manual reapplication required. My clicking finger has filed for workers' compensation.
  • Shiny hunting method: DexNav chaining? Non-existent. This is a FireRed base, so we're working with primitive technology. Chain fishing and soft resets only. Brutal.

POST-GAME TERRITORY

The CK Frontier exists. I need to be very clear about what this means.

It is a post-game feature. It is not the post-game. You fight one of 19 randomly selected NPCs you've previously encountered. That's it. That's the frontier. No Battle Factory. No Battle Pike. No rental teams or streak mechanics. Just randomized rematches.

Post-game is massive? No. Post-game is a single building with a randomizer. My completion percentage plateaued at 94.7% because I genuinely cannot determine if there's hidden content or if this is simply... all there is.

FIELD NOTE: The 5.3% gap in my completion haunts me. Is there a secret area? A hidden legendary trigger? Or did the regional development simply... stop? Intelligence unclear. Requires further investigation by braver Explorers than myself.

ANOMALY REPORT

Stability was acceptable during my expedition. No game-breaking glitches encountered, no corrupted save files, no Glitch Cities manifested. The region is functional. The custom ASM implementations held together under stress testing.

However, the "completed" status in official documentation feels generous. This is a finished main campaign with a vestigial post-game appendage. For pure story completion? Adequate. For completionist neurosis? Insufficient data to achieve 100% certainty on 100% completion. That sentence alone should tell you everything about my current mental state.

THREAT LEVEL ASSESSMENT

Difficulty felt moderate throughout. Gym Leaders employ reasonable strategies without venturing into competitive territory. Elite Four presented standard challenge scaling. No level caps detected, so over-grinding remains a viable survival strategy for cautious Explorers.

FINAL EXPEDITION NOTES

Neon Blue is a competent custom region that delivers on its core promise: new maps, new events, full badge collection, and legendary availability. The QoL innovations (IV display, field release) show genuine understanding of what trainers need.

But for my specific pathology? The incomplete documentation, the chance-based legendary triggers, the minimal post-game infrastructure—it's like being handed a puzzle with no edge pieces. I think I caught everything catchable. I believe my Pokedex is as complete as possible. But I don't know. And that uncertainty? That 5.3% gap?

It's going to keep me up at night.

100% completion took me 32 hours—or rather, 94.7% completion took me 32 hours, and the remaining percentage may not exist. This is either a testament to efficient regional design or evidence of my own descent into madness.

Expedition Status: Concluded (Pending Verification)
Pokedex Anxiety Level: Elevated
Recommendation: Suitable for casual collectors. Completionists proceed with managed expectations.
