BakkesMod on Linux with Heroic Games Launcher (Epic Games)

A step-by-step guide to get BakkesMod working with Rocket League installed via Heroic Games Launcher (Epic Games Store) on Linux.

Tested on: Fedora 43, GE-Proton10-33, Heroic 2.20.1 rpm
Should work on most distros with minor path adjustments.

---

Prerequisites

• Heroic Games Launcher installed by a native package (will work without it but it might need extra changes)
• Rocket League installed and running via Heroic Games Launcher
• GE-Proton installed (via ProtonPlus or manually into ~/.local/share/Steam/compatibilitytools.d/)
• Steam installed (even if you don't use it for RL, it`s needed for compatibility paths)
• winetricks installed (sudo dnf install winetricks / sudo apt install winetricks)

---

Step 1 Find your paths

You'll need two paths. Find them in Heroic → Rocket League → Settings:

• Wine Prefix something like /home/YOU/Games/Heroic/Prefixes/default/Rocket League
• Proton version something like GE-Proton10-33

The Proton binary will be at:

~/.local/share/Steam/compatibilitytools.d/GE-Proton10-33/

---

Step 2 Set the Wine prefix to Windows 10 and install dependencies

WINEPREFIX="/home/YOU/Games/Heroic/Prefixes/default/Rocket League" \
winetricks win10 vcrun2022

If winetricks says vcrun2022 is already installed, that's fine — skip it.

---

Step 3 Link the game into the Wine prefix

Heroic installs the game outside the Wine prefix, so the BakkesMod installer can't find it. Fix this with a symlink:

ln -s "/home/YOU/Games/Heroic/rocketleague" \
"/home/YOU/Games/Heroic/Prefixes/default/Rocket League/drive_c/Program Files/rocketleague"

---

Step 4 Install BakkesMod

Download BakkesModSetup.exe from bakkesmod.com, then run it using Proton's Wine:

WINEPREFIX="/home/YOU/Games/Heroic/Prefixes/default/Rocket League" \
~/.local/share/Steam/compatibilitytools.d/GE-Proton10-33/files/bin/wine \
~/Downloads/BakkesModSetup.exe

Go through the installer normally. If it opens a folder picker asking for the RL install location, navigate to:

C:\Program Files\rocketleague\Binaries\Win64

Verify it installed correctly:

ls "/home/YOU/Games/Heroic/Prefixes/default/Rocket League/drive_c/Program Files/BakkesMod/"
# Should show: BakkesMod.exe  unins000.dat  unins000.exe

---

Step 5 Heroic settings

In Heroic → Rocket League → Settings, make sure:

• Esync is disabled
• Fsync is enabled

Having both enabled causes a conflict that prevents the game from launching properly.

---

Step 6 Launch BakkesMod

Use the included bakkesmod.sh script, or run manually:

WINEPREFIX="/home/YOU/Games/Heroic/Prefixes/default/Rocket League" \
STEAM_COMPAT_DATA_PATH="/home/YOU/Games/Heroic/Prefixes/default/Rocket League" \
STEAM_COMPAT_CLIENT_INSTALL_PATH="$HOME/.steam/steam" \
PROTONPATH="$HOME/.local/share/Steam/compatibilitytools.d/GE-Proton10-33" \
WINEFSYNC=1 \
"$HOME/.local/share/Steam/compatibilitytools.d/GE-Proton10-33/files/bin/wine" \
"/home/YOU/Games/Heroic/Prefixes/default/Rocket League/drive_c/Program Files/BakkesMod/BakkesMod.exe"

Every session:

1. Launch Rocket League from Heroic
2. Wait until you're at the main menu
3. Run bakkesmod.sh (or the command above)
4. Press F2 in-game to open the BakkesMod menu

---

Using the launch script

Edit bakkesmod.sh and fill in your paths at the top:

WINE_PREFIX="/home/YOU/Games/Heroic/Prefixes/default/Rocket League"
PROTON_PATH="$HOME/.local/share/Steam/compatibilitytools.d/GE-Proton10-33"
STEAM_PATH="$HOME/.steam/steam"

Then make it executable and run it:

chmod +x bakkesmod.sh
./bakkesmod.sh

---

Troubleshooting

Problem	Fix
Mod is out of date, waiting for update	Click "Settings" then uncheck "Enable safe mode"
Failed to open fsync shared memory	Disable Esync in Heroic settings, keep only Fsync
BakkesMod installer can't find RL	Do the symlink in Step 3
Wine binary not found	Check your Proton version name matches exactly
BakkesMod opens but doesn't inject	Make sure RL is fully loaded to the main menu first

---

Notes

• The in-game BakkesMod GUI may not render but plugins and the console should work fine
• This guide uses umu-launcher which is what Heroic uses, that's why we need the STEAM_COMPAT_* environment variables
• Tested with GE-Proton-10-33 but should work with other Proton versions, just update the path
