⚙️ Your Environment

Showing every platform path

The cabinet hums and does nothing, which is the saddest thing a game machine can do. Rewind Arcade holds the spell that wakes it: a set of plain text files that describe thirty-eight consoles, plus the tool that turns them into a working frontend. You will cast it, understand what it wrote, and boot your first game. That game will be one you are legally free to copy.

🎯 Quest Objectives

By the end of this chapter you will:

• Install the Rewind Arcade stack using its retropi tool
• Explain the frontend, emulator, and core and how a launch flows through them
• Add a legal homebrew game and boot it in ES-DE
• Read a system manifest and tune an emulator without changing its code
• Play the browser arcade on the same machine

🗺️ Quest Prerequisites

• Chapter II — a healthy Pi running 64-bit Raspberry Pi OS with the desktop
• A monitor or TV, keyboard, and mouse on the Pi for this chapter, because ES-DE needs a graphical session
• A USB gamepad — a keyboard works for the first test

⚖️ The law of the arcade: Rewind Arcade downloads emulators and cores, and it never downloads games or BIOS files. This chapter uses a GPL-licensed homebrew game. For commercial games, use only dumps of games you own, and check the law where you live.

🌍 Choose Your Adventure Platform

Every spell in this chapter runs on the Pi. Open a terminal on its desktop, or connect from your fortress.

🐧 Linux

ssh rig@rewind.local
sudo apt update && sudo apt install -y git

The last step of Chapter 3 needs the Pi’s own screen, because a game window cannot open over a plain SSH session.

🧙‍♂️ Chapter 1: Summon the Stack

⚔️ Skills You’ll Forge

• Reading a tool’s report before letting it change anything
• Installing a layered software stack

Clone the repository and run its Pi bootstrap. It installs system packages and RetroArch, then prints advice for your board.

git clone https://github.com/bamr87/rewind-arcade.git
cd rewind-arcade
./emulate/platforms/raspberrypi/bootstrap.sh

Now ask the tool what it sees. doctor changes nothing, and it finishes with the exact commands to fix anything it found.

./bin/retropi doctor

When you are happy with its report, install the rest:

./bin/retropi install

That single command installs ES-DE, RetroArch, and the libretro cores for your enabled systems, then generates all the configuration. Allow time for the downloads.

🔍 Knowledge Check

• Which command is safe to run at any time, and why?
• What does install set up, in order?

🧙‍♂️ Chapter 2: Learn the Three Layers

⚔️ Skills You’ll Forge

• Tracing a game launch through a frontend, an emulator, and a core
• Reading declarative configuration

Three separate layers work together each time you press A on a game:

flowchart LR
    You[🎮 You pick a game] --> ES[ES-DE<br/>the frontend]
    ES --> RA[RetroArch<br/>the emulator host]
    RA --> Core[libretro core<br/>such as Nestopia]
    Core --> Game[Your game runs]

Layer	Its job	Where it lives
ES-DE	Shows your library and starts games	~/ES-DE
RetroArch	Provides video, audio, input, and saves	Installed by retropi
Core	Emulates one console	Downloaded per system

Rewind Arcade never special-cases a console in its code. A system is a single YAML file, which you can read for yourself:

sed -n 1,30p emulate/config/systems/nes.yaml
./bin/retropi systems show nes

The last line of systems show is the exact command the frontend will run. When a game will not start, that line is the fastest place to look.

🔍 Knowledge Check

• Which layer would you change to try a different NES emulator?
• Where do you find the real launch command for a system?

🧙‍♂️ Chapter 3: Boot a Game You May Keep

⚔️ Skills You’ll Forge

• Adding a game the tool can file correctly
• Proving emulation works before you add a library

Nova the Squirrel is a real NES game, released under the GPL by its author. That makes it a perfect first test.

curl -L -o ~/nova.nes https://github.com/NovaSquirrel/NovaTheSquirrel/releases/download/v1.0.6a/nova.nes
./bin/retropi roms add ~/nova.nes --system nes
./bin/retropi roms scan
./bin/retropi build

build regenerates everything that comes from the manifests. Run it after any configuration change. Now go to the Pi’s own screen, open a terminal there, and launch the frontend:

cd ~/rewind-arcade
./bin/retropi frontend launch

Find Nintendo Entertainment System, pick Nova, and play. To leave a game, press Select and Start together on a gamepad.

If ES-DE complains about OpenGL, use the fix from the project’s Pi guide:

MESA_GL_VERSION_OVERRIDE=3.3 ./bin/retropi frontend launch

🔍 Knowledge Check

• Why use --system nes instead of letting the tool guess?
• Why can’t you launch ES-DE from a plain SSH session?

🧙‍♂️ Chapter 4: Tune the Spell

⚔️ Skills You’ll Forge

• Overriding behavior through configuration, not code
• Trimming a frontend to fit its hardware

You can swap the emulator for any system without editing a manifest. Your choices land in emulate/config/local.yaml, which stays out of Git.

./bin/retropi config set emulators.nes mesen
./bin/retropi build

Mesen is more accurate than the default and heavier on a Pi. Play Nova for a few minutes, then decide. To go back:

./bin/retropi config set emulators.nes nestopia

Trim any system your board cannot run, so the menu only shows what works. On a Pi 5, Saturn is a good candidate:

./bin/retropi systems disable saturn
./bin/retropi build

Then visit the workspace’s Play pillar. Rewind Arcade also ships original browser games that need no ROMs at all. Open Chromium on the Pi and go to the live arcade. A connected gamepad drives it too.

If you already own a game collection, the Catalog pillar can tell you whether a dump is good:

./bin/cartidx init --systems nes,snes,n64

🔍 Knowledge Check

• Which file holds your local choices, and why should it stay out of Git?
• What happens if you skip build after changing a setting?

🎮 Implementation Challenge

Objective: Prove the whole chain works, then show that you understand it.

Success Criteria:

• ./bin/retropi doctor shows no failures
• Nova boots from ES-DE and takes input
• You changed an emulator, tested it, and changed it back
• Your chronicle’s README.md explains the three layers in your own words

On your fortress, in twin-rigs:

git add README.md
git commit -m "docs: explain the arcade's three layers"
