[Development] Origin – an Emulator for the 2016 v0.77a US version

[Rulake]

What this is about

This project comprises a Server Emulator for the online multiplayer racing game Drift City.


Specification

DC Origin Server is a Java based Drift City Server Emulator that is compatible with the latest KR Client from 2022. Its architecture is mainly inspired by DCNC and RiceEmu but has evolved and grown over the time. The packet logic on the other hand is inferred from the leaked Server files.


Scope and Project Goal

At project Origin we are developing a Drift City emulator for Stage 3 (post Neo City era of Drift City) that tries to mimic the behavior of the original Server as closely as possible.


Staff

As of now, our staff consists of four active developers who occupy different roles in the development process.

- Rulake: Analyzes/implements packet structures, RE, active since 11/2019 (in parallel to his activity as admin at DCR)

- Miami: Server development, active since 11/2019

- Revolve: Server development, active since 09/2020

- The developers of the JPDC emulator (with whom we regularly exchange our knowledge)


Test Server and Discord Community

The project is currently in closed alpha stage. We run a test server which is only open to our Discord community. On the Discord server, we regularly post update notes and members can submit bug reports or feature requests.

Yet, the Discord server is still closed to the public. To get access, you must be explicitly invited. We will ignore any requests for invitations, so be patient until we move into a alpha/beta stage.


Features

This list is kept small, details would go beyond the scope.

- Auth / Lobby
- Cars
- Items / Parts Shop
- Visual Items / Drift Shop
- Crews(Basic)
- Auction and Trades
- Battlezone(Basic racing)
- Quests
- HUV chase
- Multiplayer
- Traffic
- UnderCity
- Deliveries
- Rushtime


Contact

Any questions? Then contact either Rulake#1337 or Miami#5802 on Discord.


As mentioned above, the Discord server is still closed to the public. Hence, we will also regularly post updates on the current status of the project for the public in this thread.

How many people play MU Online these days? The first time I heard of this game was back when I was a boy, like in grade school.

Hey, after some time it's time to tell what we continued to do during last 3-4 weeks.

Added:
- added Undercity.
- added check for maximum upgrade level for parts (maximum upgrade/enhancement level is set to 20 atm).

Fixes:
- fixed user info (character selection view): last recently used character is shown on top.
- fixed inventory update bug: inventory is updated in the client when switching to a character with an empty inventory.
- fixed bug where equipable items where merged/stacked by the server, which looked like a single item in the client.
- fixed some log messages (that fucked with some handlers and, hence, the features provided by the handlers weren't working).
- fixed converts: solution A/B/C gives speed/accel/dura-boost converts, respectively.
