L2JVintage

Java core on aCis 3.5 (net.sf.l2j), built with JDK 21 and Ant.

GameServer, LoginServer and database in containers. One-command install.

A separate Java process that orchestrates integrations. The core is never the front door.

One core, many editions. The difference lives in data/config, not in an `if` inside the engine.

NPCs, spawns, skills, multisell and HTM reviewed, in a volume you edit without rebuilding.

A versioned database schema you can install from scratch.

Team vs Team with rewards for winner, loser and top kill; a tie rewards everyone.

Staged: Kamaloka 4th floor, Golkonda, Beleth and Tiat, with chest and guardians.

PvP kills between command channels in grand boss zones become points and a season jewel.

Trade letters for gifts, with drops and a page per word.

Zones that demand a real party: minimum inside, healer cap, one per HWID.

Spin with history, price per tier and prizes configured in XML.

A fortress siege system for Interlude, written on top of the core.

Sign-up tournament and scheduled world invasions.

XP, SP, adena and drop configurable, with a different curve per level.

One epic per group every N days — the end of the server that dies in two weeks.

Grade locking on drops, to open the server in seasons.

By item type, not by list — spellbooks and recipes off the ground.

A price map for thousands of items, from buylist and multisell, with a sell cap.

Cycles with a window per region, a random minute, and respect for Olympiad and siege.

Random 24h scatter, with no bot queue waiting for the top of the hour.

Damage, crit and resistance tunable per class and per skill, in XML.

Time-based perks, with exclusive drops and skins and its own storefront.

Looks decoupled from gear, with a catalogue, tiers and VIP-only skins.

Listings locked by objectId, fee rounded up, and delivery while offline.

Auctions in the Community Board, with history.

Saved schemes, a cubics tab, and a list of skills that cost no slot.

A daily mission with percentage bonuses and HWID protection.

A season with ranking, name reservation, coupons and weekly history.

A shop that stays up without the player, and a CB with its own tabs.

Machine identification via the client guard, with an account cap and blocking.

Server-side detection, with a suspects tab in the panel and manual punishment.

PvP between accounts on the same machine does not count.

History, alerts and a summary of what the staff created, moved and enchanted.

Vote rewards that cannot be gamed with someone else's account.

Panel-to-game commands signed with Ed25519, with a nonce and short expiry.

Flood attempt statistics, visible in the panel.

A self-updating executable with the server address built in.

A P-256 signed manifest, checked by hash on the player machine.

A cross-compiled protection DLL that reports only when integrity checks out.

A full .u, .xdat and .utx build — your own windows, buttons and textures.

The patch served from object storage, off the machine running the game.

The same pack the panel installs, monitors and controls.
