⚔️ TFS 1.8 Downgrade 8.60 — Open Source Tibia Server Base

Mateus Robeerto · Apr 23, 2026

If you're into Tibia server development and haven't seen this project yet, now's the time.

Custom fork of The Forgotten Server, downgraded to protocol 8.60 but running on the modern TFS 1.8 engine — almost 1,000 commits, 13+ exclusive systems built in pure C++ and optimizations you won't find in any standard fork.

What's already implemented:

Instance System — private dungeons per player/party

Forge System — item fusion with tiers

Imbuement System — scrolls + raw materials

AutoLoot integrated in core (zero Lua overhead)

Live Cast with EXP bonus

Token Protection — anti-theft system

System Spy for admins

Reward Boss — global Tibia style

Harmony System — new Monk vocation

Guild Wars, Guild Halls, Zones System

ClientID directly from .dat — no ServerID/ClientID mapping

DLL patches to extend CIP 8.60 client limits

And much more — read the full README on GitHub

Stable, active and optimized base. Built with -O3, mimalloc, simdutf, LTO. Runs clean on Ubuntu 22.04/24.04 and Windows via vcpkg.

How you can help:

Found a bug? Open a detailed Issue on GitHub

Know C++ or Lua? Open a PR — surgical patches are welcome

Like the project? Drop a star on the repo — it helps visibility

GitHub - Mateuzkl/forgottenserver-downgrade-1.8-8.60: TFS Downgrade 1.8+ is an engine based on nekiro downgrade but highly updated with current tfs code, it also has the lua modules divided and uses lua5.4 (https://github.com/Mateuzkl/forgottenserver-downgrade-1.8-8.60)

Me and the team appreciate any contribution — code, bug reports or technical feedback.

Good Job!

Hello

it may sound stupid but you can compile the engine for Us ?
PS: sounds good

Hello

I’ll give you a tip to make it easier.

Nowadays the project already has a vcpkg.json, so you don’t need to worry too much about dependencies manually.

What does vcpkg.json do?

It detects the required libraries and installs the dependencies automatically, including Boost and the other libs needed to compile the project.

First, delete your old vcpkg folder and install it again:

git clone GitHub - microsoft/vcpkg: C++ Library Manager for Windows, Linux, and MacOS (https://github.com/microsoft/vcpkg.git) C:\vcpkg
cd C:\vcpkg
.\bootstrap-vcpkg.bat
.\vcpkg.exe integrate install

After that, set VCPKG_ROOT globally:

[System.Environment]::SetEnvironmentVariable("VCPKG_ROOT", "C:\vcpkg", [System.EnvironmentVariableTarget]::Machine)

OBS: if you clone vcpkg to another drive, for example D:\vcpkg, use this instead:

[System.Environment]::SetEnvironmentVariable("VCPKG_ROOT", "D:\vcpkg", [System.EnvironmentVariableTarget]::Machine)

After that, open:

forgottenserver-downgrade-1.8-8.60\vc17\theforgottenserver.sln

Set the build mode to Release, then click Build Solution.
It should download and build the dependencies automatically.

One more detail:

If you are using Visual Studio 2026, keep the platform toolset as v145.

If you are using Visual Studio 2022, change the platform toolset from v145 to v143, then compile.

Can I download vcpkg directly from github? Not through git or cmd.?

This is done through Windows CMD or PowerShell.

First, you need to have Git for Windows installed:

Git - Install for Windows

git-scm.com

After installing Git, open CMD or PowerShell and choose where you want to download vcpkg.

Example for C:\vcpkg:

LUA:

git clone https://github.com/microsoft/vcpkg.git C:\vcpkg
cd C:\vcpkg
.\bootstrap-vcpkg.bat
.\vcpkg.exe integrate install

You can download it manually from GitHub as a ZIP, but I recommend using git clone, because it avoids missing files and makes updates easier later.

I downloaded it via git, the rest library is downloaded by Visual Studio. Good?

It worked. The compilation went smoothly. Thanks Roberto ; p

PS: What acc manager You preffer ?

Artvs Magnvs · Apr 28, 2026

hey man, this looks great! I wander if it has the datapack for real mal with quests/NPC/monsters etc?

Mateus Robeerto · Apr 28, 2026

Hey! Thanks man

tuduras said:

About the acc manager, you can choose between an in-game account manager or MyAAC.
I personally recommend using MyAAC, since it’s more up-to-date, has many fixes, and is actively maintained.

Regarding NPCs and monsters:
Monsters (15.23) are already fully configured for TFS, including loot and spells. They’re located in data/scripts/monsters and are fully done using revscripts.

For NPCs, there is support for both XML and Lua (revscripts). You can choose whichever you prefer — for now, I’m keeping both options available.

Also, items.otb and XML are based on Crystal Server 15.23 and are already 100% configured.

I'm in love with how smoothly this data flows, it's really good! A great contribution to the community

Mateus at it again!
Great job for making TFS, with wanted features, very accessible for newcomers and old veterans.

bakkens · Apr 29, 2026

Thanks for releasing this project

I’m going through the source code right now and it’s going to help a lot with my own project. There are a lot of really smart pointers in here!

BrownDeveloper · Apr 29, 2026

OMG Very Nice Project!! i will test it!, but what Gesior or Web are compatible with this ?

tuduras · Apr 29, 2026

@BrownDeveloper He said, prefer MyACC. BEST regards

I believe the TFS base is already quite stable. I have run some tests and, apparently, everything looks fine.The codebase has already been migrated to a more robust smart pointer model. For those who are not familiar with it, smart pointers help with automatic memory management, avoiding invalid pointers and reducing the risk of crashes, memory leaks, and several common ownership issues.TFS 1.8-8.60 - RAII / Smart Pointer Status

Code:

Area                                      Result
--------------------------------------------------
Common/owning new T in src/               0
Common/owning delete ptr in src/          0
std::make_unique / make_unique<           133
std::make_shared / make_shared<           76
unique_ptr references                     142
shared_ptr references                     382
weak_ptr references                       88

Still, if anyone finds a bug, strange behavior, or something that is not working correctly, feel free to fix it, open a PR, and send it to the repository.Any help is very welcome. Let’s keep the base stable and continue improving it for the future.

But I don't get it. Downgrading should mean I only have features up to 8.6. Is it possible to have the same experience as TFS 0.4 (3777/3884) and nothing newer?

Actually, the idea is almost the opposite.
The goal of the downgrade is not to limit the base to TFS 0.4, but to bring the old 8.60 protocol into a more modern engine, with updated features, fixes, and improvements that never existed or were never properly fixed in the old bases.

In short: old-school experience, but with a newer structure underneath.

Yes you can download it directly from their repository
