GNU/Linux software to give TAS tools to games. Code orginates from SuperMeatBoyTaser. It requires a GNU/Linux system with a recent kernel (at least 3.17 for the memfd_create syscall). Supported archs are x86_64 and x86 (not much tested). To run OpenGL games, you will need a card supporting at least OpenGL 3.0.
Most work has been done to support games using the SDL library (which is the case of many indie games), and there is initial developpement to support other game engines (some Unity games should work). Also, Steam games won't work because Steam messes up with our code injection, so you must check if a drm-free version of the game exists. For more details, check the Game Compatibility page.
You can download the latest version of the software in the Releases page. The current dependancies are:
libc6,libgcc1,libstdc++6libqt5core5a,libqt5gui5,libqt5widgets5with Qt version at least 5.6libx11-6,libxcb1,libxcb-keysyms1,libxcb-xkb1,libxcb-cursor0ffmpeglibswresample2,libasound2libfontconfig1,libfreetype6libtar0,zlib1g
Installing with the debian package will install all the required packages as well.
If you don't have a Linux system beforehand, an easy way is to use a virtual machine to run the system. Grab a virtualization software (e.g. VirtualBox) and a Linux distribution (e.g. Ubuntu) whose architecture matches a supported architecture of the game you want to run (in most cases amd64, sometimes only i386 is available). Note for Ubuntu users that you need a recent version (17.10 minimum).
If you want to compile it yourself, you will need cmake. From the root directory just type:
mkdir build
cd build
cmake ..
make
The current mandatory dependancies so far are libx11-dev, qtbase5-dev, qt5-default, libtar-dev, zlib1g-dev, libsdl2-dev, extra-cmake-modules, libxcb1-dev, libxcb-keysyms1-dev, libxcb-xkb-dev, libxcb-cursor-dev, libasound2-dev, libswresample-dev
To enable HUD on the game screen, you will need libfreetype6-dev, libfontconfig1-dev
Cmake will detect the presence of these libraries and disable the corresponding features if necessary.
If you want to manually enable/disable a feature, you must add just after the cmake command:
-DENABLE_HUD=ON/OFF: enable/disable displaying informations on top of the game screen-DENABLE_FILEIO_HOOKING=ON/OFF: enable/disable file opening/closing hooks to handle savefiles
Be careful that you must compile your code in the same arch as the game. If you have an amd64 system and you only have access to a i386 game, the easiest way is to build a virtual machine with a i386 system. You could also try to cross-compile the code to i386. To do that, use the provided toolchain file as followed: cmake -DCMAKE_TOOLCHAIN_FILE=../32bit.toolchain.cmake ... However, many users failed to do this due to some libraries that don't like this operation.
To run this program, just type:
./linTAS [game_executable_path [game_cmdline_arguments]]
You can type ./linTAS -h to have a description of the program options.
The program prompts a graphical user interface where you can start the game or change several options. Details of the different options are available here
There are a few things to take care before being able to run a game. You might want to look at the software usage.
Here are the default controls when the game has started:
- frame advancing, using the
Vkey - pause/play, using the
pausekey - fast forward, using the
tabkey
Note: the game starts up paused.
