What is Steamless
Steamless is a DRM remover for the SteamStub DRM that has been added to most newer games released on Steam.

Main Repository
Legal
I, atom0s, am not responsible for what you do with this source code. I do not condone piracy and wish that if you choose to remove the DRM of a Steam game, do so with a game that you already own. Use this code at your own risk!

Notes
I am not releasing a binary form of this project for legal reasons.
Instead, the code is posted as an educational piece of work.

The code is compiled using Visual Studio 2015.

Special Note: This will only remove the SteamStub DRM. If the game makes use of the steam_api.dll file, then you will need to manually remove the usage of that file yourself. (Or create a proxy DLL that just nulls all the exports so that the game assumes its working etc.)

I have moved this project to Gitlab as Github has been bought over by corporate greed.
https://gitlab.com/atom0s/Steamless
https://gitlab.com/atom0s/Steamless.NET

(This has undergone a lot of updates since I posted here last. The Steamless repo is now the main repo and is maintained in C# rather then C/C++. It supports v2, v3 and v3.1 of SteamStub DRM now.)

Any chance on a compiled build for the latest version?

For legal reasons, no. I do not distribute compiled binaries for this. You can download Visual Studio for free and compile it yourself though. Visual Studio community is free:

Steamless v3
Image

Info
I decided to rewrite Steamless with a UI since I had a lot of emails / private messages from people asking me how to use the old version etc. Along with that, the older version was not extendable or friendly to others developing unpackers. This new version is now fully done via plugins (Example plugin source code is included in the release) allowing others to easily create their own unpackers.

v3.0.0.8
  • General code cleanup.
  • Added new experimental features option.
  • Added new SteamStub 2.x variant offset dumper. (Experimental Feature)

The new SteamStub 2.x variant offset dumper should be able to dump most of the v2 files that would fail before. This newer feature is experimental for now and uses disassembling to pull the offsets instead. This has only been tested on a few files so far, but all seems to work ok. In order to use this feature, you must check the new 'Use Experimental Features' box before attempting to unpack a file.
