MapleStory Classic World — Datamined Metadata Analysis

Source: WZ metadata dump (3,859 files, 416 MB across 46 WZ archives)
Binary context: MapleStory_0_zucx.exe v1.1.0.0, Themida-protected, signed April 6, 2026
Status: Unreleased — likely Closed Beta or internal QA build


Executive Summary

MapleStory Classic World is dramatically more restrictive than anyone expected. This is not a "v62" or "v83" recreation. It's closer to Beta MapleStory / GMS v.0.0x–v.28 — the earliest era of the game, rebuilt on the modern engine. The data confirms:

  • Only 4 Explorer classes (Warrior, Magician, Bowman, Thief) — no Pirates
  • Only 1st and 2nd job advancement — no 3rd job, no 4th job
  • Only Victoria Island + Maple Island — no Ossyria, no El Nath, no Ludibrium, no Orbis
  • 91 monsters total (live MapleStory has thousands)
  • 304 maps total (live has tens of thousands)
  • 188 NPCs — classic Victoria Island cast
  • Redesigned scroll system (Lesser/Intermediate/Greater/Chaos tiers)
  • Zero cubes, zero starforce in the consumables data
  • Free Market is IN with 11 channels
  • Kerning PQ confirmed (1st Accompaniment maps present)
  • Brand new exclusive content: "Shallow Passage" and "Deep Passage" areas with new monsters not from any prior version

5. Items & Economy

Scrolling System — REDESIGNED

The classic 10%/60%/100% scroll system has been completely replaced with a 4-tier system:

TierNameSuccess RateEffectNotes
Lessere.g. "Hat Accuracy Scroll: Lesser"100%+1 statAlways succeeds, lowest bonus
Intermediate"Hat Accuracy Scroll: Intermediate"60%+2 statMedium risk/reward
Greater"Hat Accuracy Scroll: Greater"10%+3 statHigh risk, high reward
Chaos"Hat Accuracy Scroll: Chaos"10%+5 statHighest reward, cursed: 100 (destroys on fail)

Key observation: Lesser scrolls link to itemID1, itemID2, itemID3 — pointing to the Intermediate, Greater, and Chaos versions. This suggests a scroll upgrade/fusion system where you can combine Lesser scrolls into higher tiers.

216 total scrolls covering: Hats, Earrings, Topwear, Overall Armor, Bottomwear, Shoes, Gloves, Shields, Capes, 1H Swords, 1H Axes, 1H Blunts, Daggers, Wands, Staves, 2H Swords/Axes/Blunts, Spears, Polearms, Bows, Crossbows, Claws, Pet Equipment

What's NOT in Consumables

  • No Cubes — zero cube items in the entire consumable database
  • No Starforce items — no Star Enhancement scrolls
  • No Flames / Bonus Stats items
  • No Nebulites
  • No Spell Traces

Potions — Classic Set Only

Red Potion, Orange Potion, White Potion, Blue Potion, Elixir, Power Elixir, Mana Elixir, Warrior/Magic/Sniper/Dexterity/Speed Potions

Throwing Stars

Subi, Wolbi, Mokbi, Kumbi, Tobi, Ilbi, Hwabi — the classic star progression

Free Market

Confirmed present — Free Market Entrance + 11 channels (FM 1-11)

7. Modern Remnants (Live Client Artifacts)

The metadata contains numerous artifacts from the modern live client that are NOT active in Classic World but exist because Classic World shares the modern client codebase:

BossParty.img — 36 Boss Entries (Remnants)

Zakum, Horntail, Hilla, Pierre, Von Bon, Crimson Queen, Vellum, Von Leon, Arkarium, and more are defined in the boss party system. However, none of their maps exist in the Classic World map data — these are data remnants carried over from the shared codebase.

SpecialServerInfo.img — World Type Definitions

Contains definitions for: Reboot ("Heroic World"), Burning World, Challenge World, Yeti x Pink Bean World, and PL_SP (Private Server?). There is no "Classic" entry in this file — confirming Classic World is handled differently (likely via the classic flag found in the binary).

potentialCostTable.img — Potential System Data

Full potential cost tables exist (Rare/Epic/Unique/Legendary tiers, meso costs by level). However, since there are zero cubes in the consumable data, the potential system appears to be inactive/disabled. The data is a remnant.

CraftRecipe.img (954 KB), RuneStone.img (4.1 MB)

Modern crafting recipes and Rune Stone data are present but likely non-functional — crafting stations exist as NPC data (Weaponcrafting, Sewing, Woodworking, Leatherworking, Arcane) but these may be simplified versions.

DamageSkin.img, ForceAtomInfo.img

Modern damage skin and force atom (projectile) systems are present as data but likely only used for the classic-compatible subset.


8. Community Wishlist Cross-Reference

The MapleStory community has been vocal about what they want (and don't want) in Classic World. Sources include Reddit, Steam forums, MMOBomb, DigitalTQ playtest coverage, maplestoryclassicworld.com community analyses, and MapleCon 2025 press coverage. Here's how the datamined reality compares.

✅ Confirmed — Community Gets What They Want

Community WantStatusEvidenceCommunity Context
Manual AP allocationCONFIRMEDBinary: SID_MSCW_ASK_STATUP_AP_AMOUNTUniversally requested. Community also wants HP Washing removed — Nexon playtests showed higher Mage HP than expected, suggesting rebalanced HP formulas
Original 4 ExplorersCONFIRMEDOnly Warrior/Mage/Bowman/Thief skill dataExact match to community expectation for launch
No Pirates at launchCONFIRMEDNo job 500+ skills, no Knuckle/Gun weaponsDivisive — purists happy, pragmatists wanted them. MMOBomb: "Pirates should be in from the beginning. They're an Explorer." Expected in a later phase
No 5th/6th jobCONFIRMEDZero 5th/6th job skill data in WZ filesUnanimously rejected by community. Binary has 6th job strings but these are engine remnants, not active content
No StarforceCONFIRMEDZero starforce items in consumablesUnanimously rejected
No Potential/CubesCONFIRMEDZero cube items; potentialCostTable.img exists but is an unused remnantUnanimously rejected. Community's #1 anti-P2W demand

⚠️ Modified — Present But Different Than Expected

Community WantStatusEvidenceCommunity Context
Classic 10%/60%/100% scrolls⚠️ REDESIGNEDNew Lesser (100%)/Intermediate (60%)/Greater (10%)/Chaos (10%, cursed) tiers with fusion mechanicCommunity nostalgic for old scrolling RNG. The new system preserves the risk/reward element but adds an upgrade path (fuse Lesser → Intermediate → Greater). The Chaos tier's cursed: 100 means guaranteed item destruction on failure — preserving the classic gamble. This will be controversial — purists want the exact old system
No P2W Cash Shop⚠️ UNKNOWNCash Shop item data not in WZ metadata dumpCommunity's #1 fear. Significant portion would prefer $10-15/mo subscription over F2P. Unanimous rejection of: Gachapon, 2x EXP coupons, AP Reset scrolls, Vicious Hammer, Marvel Machine. "The target audience isn't children. We're 'old heads' with disposable income."
Phased content rollout⚠️ STRONGLY IMPLIEDOnly 2nd job + Victoria Island = must be Phase 1 of manyCommunity wanted phased approach (WoW Classic style). Nexon's "Origins, Evolution, Beyond" pillars confirm this. But starting at 2nd job is earlier than most expected — community assumed 3rd or 4th job at launch
EXP curve (old rates)⚠️ UNKNOWNBinary loads EXP table from WZ via expTableNo — actual values not in this dumpMost heated community debate. Purists want 1x; moderates want slight boost ("Us OGs have lives now"). DigitalTQ playtests suggest original EXP tables. Binary has ExpBuffRate, PlusExpRate, and playtime_initial_exprate (fatigue system?)

❌ Missing — Community Wants It But It's Not Here (Yet)

Community WantStatusEvidenceCommunity Context
Up to 3rd job at launchONLY 2ND JOBNo 3rd job skill files (no Crusader, Hermit, Ranger, Priest, etc.)Most speculation centered on v62 (3rd job cap) or v83 (4th job). 2nd job cap is earlier than almost anyone expected
Up to 4th job eventuallyNOT YETNo 4th job skill filesMajority wants 4th job in a later phase. Small purist minority wants permanent 3rd job cap at level 120
ZakumNOT PLAYABLEBoss entry in BossParty.img but no El Nath mapsUniversally expected as endgame. Will require Ossyria expansion
HorntailNOT PLAYABLEBoss entry exists but no Leafre mapsExpected as ultimate endgame in later phase
Ossyria (El Nath, Ludi, Orbis)NOT PRESENTZero Ossyria maps in dataExpected in Phase 2/3
Ludibrium PQ, Orbis PQNOT PRESENTNo Ludibrium/Orbis mapsExpected with Ossyria expansion
Balanced classesUNKNOWNSkill data exists but damage values need deeper analysisStrong demand to buff Bowmen, address Bishop being valued only for Holy Symbol, tune Night Lord damage, rework Chief Bandit meso mechanics
Anti-bot/anti-cheatINFRASTRUCTURE EXISTSBinary: XignCode3, lie detector, GM stalker mode, anti-macro timersCommunity's #2 fear after P2W. Infrastructure is present in the binary
Leeching changesUNKNOWNNo EXP sharing rules visible in metadataExtremely divisive. Steam thread OP suggests EXP restriction based on level difference (15-20 level range)

9. Key Surprises & Observations

1. This is Earlier Than Anyone Expected

Most community speculation centered on v62 (3rd job cap) or v83 (4th job). This data suggests Classic World launches at roughly v.0.28 era — pre-Ossyria, pre-3rd job, pre-Pirates. This is "Maple Island + Victoria Island and nothing else" era.

2. The Scroll System is Completely New

The old 10%/60%/100% scroll system that players are nostalgic for has been redesigned. The new Lesser/Intermediate/Greater/Chaos tier system with the itemID1/2/3 linking suggests a scroll fusion/upgrade mechanic. The Chaos tier's cursed: 100 means guaranteed destruction on failure — preserving the gambling element but with a new framework.

3. "Classic Plus" is Real

The 10 new monsters and 17 new maps (Shallow/Deep Passage) confirm this isn't a pure restoration — it's "Classic Plus" with original content designed to extend endgame beyond what existed in early MapleStory.

4. Crafting Infrastructure Exists

Cave Fairy NPCs include an "Arcforger" (Nyroth) and Sleepywood has "Chrishrama" (Arcforger) and "Eurek the Alchemist." These suggest a new crafting system specific to Classic World — possibly for the Shallow/Deep Passage gear.

5. Content Will Be Phased

Starting at 2nd job cap with Victoria Island only strongly implies a phased content release plan — 3rd job + Ossyria in a later patch, 4th job even later. This mirrors how the original game grew and how WoW Classic operated.

6. "Rotten Mushmom" is the Top Boss

With no Zakum or Horntail maps, the highest-tier boss appears to be Rotten Mushmom (700003) and Jr. Balrog (700001). The Deep Passage's "Bygone Days" may contain a new endgame boss not yet revealed in the string data.

7. The Binary Has Everything, The Data Has Almost Nothing

The executable binary contains the full modern damage formula engine (damR, bossDamR, finalDamR, 6th job skill references, etc.), but the WZ metadata is stripped down to only what Classic World needs. This confirms the "modern engine, classic content" architecture.
