Some challenge

Neil/Tyra, the genius scientist who became a professor. He/she has a dream. He/she wants to make the strongest Pokemon by himself, he did so many experiments. However, he/she doesn’t have enough money. At this time, a businessman called Kasper tells the young professor that he would contribute to the project, but the Professor must share the achievement with him. To reach his/her goal, he/she accepted Kasper’s contribution without hesitating. As the young genius gradually knows that Kasper is the leader of a secret team called “Team Delta”, he/she begins to think about whether he/she should keep up. Why does Kasper need the project? What will he do? The young professor must decide, whether to keep it up, or not.

MISSION REPORT: POKEMON MEGA POWER

Explorer: DexHunter Ace (LVL. 100)
Expedition Duration: 67 hours, 23 minutes
Pokedex Completion: 94.7% (AND IT'S KILLING ME)
Status: Returned. Exhausted. Slightly unhinged.

INITIAL ASSESSMENT

Three regions. THREE. Ivara, Lande, and the Sevii Islands. When I first received this mission briefing, my hands started shaking. That's a LOT of tall grass to comb through. A lot of hidden corners. A lot of potential for that beautiful, beautiful 100%.

I was wrong to be excited. I was also right. It's complicated. Like my relationship with my spreadsheets.

THE LANDSCAPE

The Ivara region opens strong—custom tilework that doesn't look like someone's first attempt at AdvanceMap. The visual landscape shifts dramatically as you move between regions, with Lande offering more industrial zones and the Sevii Islands providing that nostalgic archipelago feel. The world is MASSIVE. I clocked significant exploration time just mapping routes, and I'm still finding caves I missed.

But here's where my eye starts twitching: the region design is ambitious to a fault. Some areas feel like they were built for spectacle rather than navigation. I got lost in Lande's power plant complex for two hours. TWO HOURS. My Repels were crying.

POKEDEX ANALYSIS

Okay. Deep breaths. Let me tell you about the Pokedex situation.

The roster pulls from Gens 1-7, including Mega Evolutions. On paper? Chef's kiss. In practice? Missable event warning! Save before entering the cave. Actually, save before entering ANYTHING. Some Pokemon are locked behind story choices that the game does NOT telegraph clearly. I learned this the hard way with a certain legendary encounter in Lande.

FIELD NOTE: The scientist storyline branches. Your choices affect Pokemon availability. I repeat: YOUR CHOICES AFFECT POKEMON AVAILABILITY. Keep multiple save states or accept eternal incompleteness.

The good news: most standard Pokemon are obtainable through normal exploration. Trade evolutions? Here's where I have to deliver mixed intel. Link Cable item is available in Department Store. Huge W. But it's not available until late-game Lande, which means you're dragging around your Haunter and Kadabra for HOURS waiting for that sweet, sweet evolution.

Living Dex is possible without cheats. Technically. If you make the right story choices. If you don't miss the one-time encounters. If you have the patience of a Snorlax in a berry field. I'm at 94.7% and the remaining 5.3% haunts my dreams.

QUALITY OF LIFE PHENOMENA

This is where Mega Power shows its age. The hack is ambitious—maybe TOO ambitious for its era. Some modern QoL features we've come to expect are simply absent:

  • No infinite Repel toggle (my poor A button)
  • No built-in Nuzlocke mode
  • EV/IV checking requires external tools or specific NPCs that are easy to miss
  • No speed-up integration (though emulator-side fixes this)

However, the Mega Evolution system is implemented cleanly. Mega Stones are scattered throughout all three regions with reasonable logic—check caves, check post-gym rewards, check that suspicious NPC who definitely isn't hiding something.

THREAT LEVEL ASSESSMENT

The hostile entities in this region operate on an inconsistent difficulty curve. Early Ivara felt appropriately challenging. Mid-game Lande? Suddenly enemy trainers are running optimized sets while I'm still figuring out where to grind. The Elite Four across regions will END you if you're not prepared.

Boss battles with Team Delta are genuinely strategic. Kasper's team composition suggests someone who actually understands competitive Pokemon. I respect it. I also threw my device twice.

POST-GAME EXPEDITION

Here's the thing that keeps me from rating this higher: the post-game exists, but it's... fragmented. After the main story concludes (and what a story—the Neil/Tyra moral dilemma actually pays off), you get access to additional legendary hunts and the Sevii Islands expansion. Post-game is massive. Battle Frontier included. Well, a Battle Frontier-style facility, anyway. It's not the full Emerald experience, but it's SOMETHING.

Shiny hunting viability? Middling. No DexNav equivalent. No chain fishing mechanics that I could identify. You're doing it old-school: random encounters and prayer. My shiny count after 67 hours: 2. Both Zubats. I'm fine. I'm completely fine.

ANOMALY REPORT

Encountered several glitches during the expedition:

  • Text overflow in certain story sequences (cosmetic, not game-breaking)
  • One softlock in Lande's ice cave—save frequently
  • Occasional sprite layering issues in crowded areas
  • One Pokemon's cry was replaced with... silence? Unsettling.

Nothing that destroyed my save file, but enough to keep me paranoid. The Beta 5.71 designation is accurate—this feels like a project that reached "complete enough" rather than "polished."

FINAL EXPEDITION NOTES

100% completion took me 85 hours. Wait, no. 100% completion WOULD take approximately 85 hours if I could actually GET there. I'm stuck at 94.7% because of a story choice I made 40 hours ago. Do I start over? Do I live with the incomplete Pokedex? This is the question that will follow me to my grave.

Mega Power is a monument to ambition. Three regions, a genuinely engaging story about scientific ethics and corporate manipulation, and a Pokemon roster that spans generations. But it's also a monument to the era before ROM hacks standardized QoL features. You'll work for your completion here. You'll SUFFER for it.

I respect it. I'm also exhausted.

FINAL WARNING: If you're a completionist like me, research the story branches BEFORE you play. Check community guides for missable Pokemon. Make backup saves at every major decision point. Trust no one. Especially not that businessman Kasper. He seems nice but he's definitely up to something.

The Pokedex calls. It always calls. Even when it's 94.7% complete and mocking me.

DexHunter Ace, signing off. I need to lie down and stare at my spreadsheet.
