Hacking Batocera: Installing Claude Code on a Retro Gaming Console OS
How I got Anthropic's Claude Code CLI running on Batocera OS - from wrestling with pacman to portable Node.js solutions
When Retro Gaming Meets AI Development
Picture this: you’ve got a sleek mini-PC running Batocera, transformed into the ultimate retro gaming console. Thousands of classic games at your fingertips, perfect emulation, clean interface. But what if you could also turn that same box into an AI-powered development workstation? That’s exactly what I set out to do when I decided to install Claude Code on my Batocera system.
TL;DR: Batocera’s pacman isn’t actually Arch’s pacman, so pacman -S nodejs npm fails. Solution: install portable Node.js under /userdata and you’re golden.
What is Batocera?
For those unfamiliar, Batocera is a Linux-based retro gaming distribution that transforms any PC into a dedicated emulation station. Think of it as the ultimate retro gaming operating system:
Key Features:
- Plug-and-play emulation: Supports 150+ gaming systems from Atari 2600 to PlayStation 2
- Beautiful frontend: Clean, controller-friendly interface built on EmulationStation
- Zero configuration: Most systems work out-of-the-box with optimal settings
- Kodi integration: Media center capabilities for streaming and local content
- Network play: Built-in netplay support for multiplayer retro gaming
- Live USB capable: Can run entirely from a USB drive without installation
The Architecture That Matters: Batocera is built on a read-only filesystem with a few key directories:
/- Immutable system partition (survives updates)/userdata- Persistent user data (ROMs, saves, configs)/userdata/system- User customizations and scripts
This design makes it incredibly stable for gaming but presents unique challenges for development work. The system won’t break, but installing traditional packages requires creative solutions.
The Challenge: Batocera Isn’t Your Typical Linux
Batocera is designed like console firmware—immutable, curated, locked down for stability. This is fantastic for emulation reliability, but it creates some interesting puzzles when you want to install development tools:
- No apt: This isn’t Ubuntu
- Already root: No sudo needed (or available)
- Fake pacman: Batocera’s pacman only serves Batocera-specific packages, not Arch repos
- Read-only filesystem: Most of the system is immutable
- Persistent storage: Only
/userdatasurvives reboots and updates
When I first tried the obvious approach, I was greeted with disappointment:
[root@BATOCERA /userdata/system]# pacman -S nodejs npm
error: target not found: nodejs
error: target not found: npm
Time for some creative problem-solving!
Solution A: Portable Node.js (The Clean Path)
The most reliable approach is to install official Node.js binaries directly under /userdata/opt where they’ll persist across reboots and system updates.
Step 1: Download and Install Node.js
# Create persistent directory
mkdir -p /userdata/opt && cd /userdata/opt
# Auto-detect CPU architecture
case "$(uname -m)" in
x86_64) FLAVOR=linux-x64 ;;
aarch64) FLAVOR=linux-arm64 ;;
armv7l) FLAVOR=linux-armv7l ;;
*) echo "Unsupported arch: $(uname -m)"; exit 1 ;;
esac
# Get latest LTS (v22.x) tarball for your architecture
TARBALL=$(wget -qO- https://nodejs.org/dist/latest-v22.x/ \
| awk -v f="$FLAVOR" -F'"' '$0 ~ "node-v22[0-9.]*-" f"\\.tar\\.xz" {gsub(".*/","",$2); print $2; exit}')
# Download and extract
wget "https://nodejs.org/dist/latest-v22.x/${TARBALL}"
tar -xJf "${TARBALL}"
ln -sfn "${TARBALL%.tar.xz}" node-current
Step 2: Make It Persistent
Batocera runs /userdata/system/custom.sh at boot, so we’ll use that to persist our environment:
# Add Node.js to PATH and configure npm
cat >> /userdata/system/custom.sh <<'EOF'
export PATH=/userdata/opt/node-current/bin:$PATH
npm config set prefix /userdata/npm-global >/dev/null 2>&1 || true
export PATH=/userdata/npm-global/bin:$PATH
# Prefer IPv4 (helps with flaky IPv6 on some routers)
export NODE_OPTIONS=--dns-result-order=ipv4first
EOF
# Apply immediately
source /userdata/system/custom.sh
Step 3: Install Claude Code
# Verify Node.js installation
node -v
npm -v
# Install Claude Code globally
npm i -g @anthropic-ai/claude-code
# Launch it!
claude
And just like that, you should see the welcome banner:

Solution B: Flatpak SDK (Alternative Approach)
If you prefer containerized environments, Batocera supports Flatpak. You can run Node.js inside the Freedesktop SDK:
# Add Flathub if not present
flatpak remotes | grep -q flathub || \
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
# Install SDK and Node extension
flatpak install -y flathub org.freedesktop.Sdk//24.08
flatpak install -y flathub org.freedesktop.Sdk.Extension.node22//24.08
# Enter SDK shell
flatpak run --command=bash org.freedesktop.Sdk//24.08
# Inside the shell: enable Node and set writable prefix
[ -f /usr/lib/sdk/node22/enable.sh ] && source /usr/lib/sdk/node22/enable.sh || export PATH=/usr/lib/sdk/node22/bin:$PATH
npm config set prefix "$HOME/.npm-global"
export PATH="$HOME/.npm-global/bin:$PATH"
npm i -g @anthropic-ai/claude-code
claude
Troubleshooting Network Issues
DNS Resolution Problems (EAI_AGAIN)
If npm can’t resolve package registry domains, it’s usually DNS in the sandbox. For the Flatpak approach, you can temporarily pin hosts:
# Inside the SDK shell
IP="$(flatpak-spawn --host getent hosts registry.npmjs.org | awk '{print $1; exit}')"
[ -n "$IP" ] && printf '%s registry.npmjs.org\n' "$IP" >> /etc/hosts
For the portable Node approach, fix DNS at the host level by editing your ConnMan Wi-Fi service settings.
Connection Timeouts (ETIMEDOUT)
This usually indicates IPv6 routing issues or firewall blocks. The NODE_OPTIONS=--dns-result-order=ipv4first flag in our setup helps with the former.
You can test connectivity directly:
busybox nc -vz api.anthropic.com 443
Why This Approach Works
Zero System Mutations: Everything lives under /userdata, survives Batocera updates, and can be easily removed.
Predictable: No reliance on Batocera’s package repositories having what we need.
Recoverable: If a global package misbehaves, just nuke /userdata/npm-global and reinstall.
Portable: The same approach works across x86_64, ARM64, and ARM7 systems.
The Bigger Picture: AI-Powered Retro Gaming
Now here’s where things get interesting. With Claude Code running on Batocera, I can:
- Analyze emulator configurations: Let Claude examine RetroArch configs and suggest optimizations based on the games I’m playing
- Automate ROM organization: Generate scripts to sort and categorize game libraries
- Create custom overlays: Design system-specific bezels and overlays for different consoles
- Performance tuning: Analyze system specs and auto-configure emulator settings for optimal performance
Imagine pointing Claude at your retroarch.cfg and asking: “What settings should I adjust for better Saturn emulation on this hardware?” Or having it generate a script that automatically applies the best shaders for each console type.
The combination of retro gaming nostalgia and cutting-edge AI assistance creates some fascinating possibilities.
Future Experiments
This is just the beginning. Some ideas I’m exploring:
- Automated game compatibility testing: Use Claude to analyze emulator logs and suggest fixes for problematic ROMs
- Custom frontend development: Build React-based interfaces that integrate with EmulationStation
- Community contributions: Generate patches and improvements for Batocera itself
- Cross-platform development: Use the same setup for developing homebrew games for retro consoles
Wrapping Up
Converting a mini-PC to run Batocera is already a fun weekend project. Adding modern AI development tools to the mix? That’s where the real magic happens.
The key insight is understanding Batocera’s architecture: it’s an appliance OS that wants to stay locked down, but /userdata gives us a persistent playground for experimentation. Work with the system’s design rather than against it, and you can create some pretty powerful hybrid setups.
Whether you’re analyzing emulator configs, developing homebrew games, or just having fun with AI-powered automation, this foundation opens up a world of possibilities.
