protonhax

Tool to help running other programs (i.e. Cheat Engine) inside Steam's proton.

Usage

Set the steam game launch options to protonhax init %COMMAND%

On your Steam Library:

• Right-click the game > Properties > General.
• Set Launch Options as protonhax init %COMMAND%.

Now, you can use your terminal to run the following commands:

• To list all running appids use\ protonhax ls

• To run a program with proton use\ protonhax run <appid> <path/to/program> [args...]\ NOTE: The PATH variable is ignored

• To run cmd.exe use\ protonhax cmd <appid>

• To run a program natively with the environment variables that were used to launch the game originally use\ protonhax exec <appid> <path/to/program> [args...]\ NOTE: The PATH variable is ignored

Installation

protonhax is currently a single bash script, you just need to add it to your $PATH.

1. Either clone our repo https://github.com/jcnils/protonhax.git, or download the source from our release page
2. Copy the protonhax file to where you preffer and give it permission to execute:
   • Example of locations $HOME/.local/bin/protonhax, /usr/bin/protonhax. They need to be on your $PATH
   • Permission chmod 755 protonhax.

Arch Linux

• https://aur.archlinux.org/packages/protonhax
• https://aur.archlinux.org/packages/protonhax-git/

Debug and Troubleshoot

Enable protonhax log

Open the protonhax file and add to the second line

set -x
exec >/tmp/protonhax.$$.log 2>&1

It will save protonhax debug log into /tmp/protonhax.*.log

$PATH

Make sure protonhax is in your $PATH.

Open a terminal and run protonhax, if you do not see instructions, go back to the installation process.

If your game does not start, make sure Steam can see and access your $PATH.

Depending on how you install and execute Steam, Steam will only have access to a few locations. Like using distrobox or flatpak. Please check the issues page for flatpak workaround.

If your Steam is host installed, starting Steam from a terminal will make sure it can see your $PATH

Steam

You can check Steam's log - location will vary depending on how you installed it (check their docs). Or start Steam from a terminal and look for the messages.

When you run protonhax, e.g. `protonhax cmd 12345*, you should see in the logs :

Adding process 44444 for gameID 12345
Adding process 44445 for gameID 12345

The process number will vary, and gameID will match to your game.

Proper file path - CMD

You might be having indications that protonhax cannot find the program you are trying to execute. That can be an issue with file path solving.

Try to run protonhax cmd 12345to confirm if it works.

If it works, you might want to try to store your program in a path with no spaces and special characters, and pass the full path to protonhax to make sure.

Issues page.

You can check the issue pages for similar problems, and don't be shy to open one in case you need help troubleshooting. It always helps to make protonhax better.

Contributing

Contributions are always welcome! Especially if they are packages for other distributions.

Running programs BEFORE the game.

Protonhax is not necessary, you can set your launch options to switch paths. Example:

eval $(echo "protonhax init %command%" | sed "s|path/to/game.exe|path/to/your.exe|") More
