EmulatorJS Arcade 1.1.0：在 Windows、Mac 和 Android 上与好友在线玩复古游戏

EmulatorJS Arcade, a free and open-source retro front-end for Windows, Mac and Android, has reached version 1.1.0. Built on top of EmulatorJS, it turns a folder of legally dumped games into a "retro arcade": a cover-art wall for 20+ systems (arcade/FBNeo, NES, SNES, Game Boy/GBA, N64, DS, Mega Drive/Sega CD/Saturn, PlayStation, PSP, PC Engine and more) that you can play alone or online with friends. Full disclosure: I'm the author. I'm not a programmer and built it with a lot of help from an AI coding assistant, because I wanted to play arcade games again with old friends who now live in other cities.

The main idea is drop-in online play, like walking up to an arcade cabinet. The lobby lists every game being played right now; click "Join" and you become player 2, 3 or 4 without the host stopping or sending an invite. In arcade games you can even insert a coin and press Start mid-game. Players on the same Wi-Fi find each other automatically, and over the internet the app connects through a small lobby server that anyone can host with a single setup script. Voice chat, spectators and per-player latency are built in.

Version 1.1.0 focuses on phones and tablets:

• The on-screen gamepad now looks like each system's own controller: NES, SNES, Mega Drive, PS1, N64, GBA, Game Boy and an arcade stick panel, with matching button colors
• Portrait: the game sits on top and the controller below. Landscape: the controller is split to both sides of the picture so it doesn't cover the game, and its size can be adjusted per system
• Buttons animate when pressed, with a short vibration on Android phones that support it
• A real controller (Xbox etc.) becomes player 1 automatically and the touch controls hide themselves; unplug it or tap the screen to bring them back (handy on Meta Quest with an Xbox controller)
• CRT filter on by default for home consoles on Android, and a fix for a "connection refused" error after updating

Downloads include a self-updating Windows installer, a portable zip, Apple Silicon and Intel builds for Mac, an Android APK (also runs on Meta Quest), and a "folder version" that you start with a small script and play in your browser. No games are included. The console screenshots use free homebrew (Super Boss Gaiden, Cave Story MD, Anguna, Blastah); the arcade one is Aero Fighters.

Library

• Point it at a folder (or your existing RetroArch folders) and games are sorted by system on a cover-art wall
• Box art, title screens and screenshots can be downloaded automatically
• Recently played list, search, color themes and 10 UI languages

Online play

• Same Wi-Fi: other players show up automatically, no setup
• Over the internet: connect through a lobby server. A single script sets one up on an Ubuntu VPS (HTTPS and a relay for strict NATs included)
• Drop-in "Join" from the lobby, up to 4 players depending on the system, spectators and voice chat
• Room controls: per-player latency, kick players, allow only registered players, lock the game so nobody can join
• Optional accounts with friends, win/loss stats, a leaderboard and an "arena" mode that invites challengers
• An experimental rollback mode for fighting games

Playing

• Xbox / PlayStation controllers work out of the box, plus a menu you can drive with the controller
• Save states, per-game turbo buttons, CRT shaders
• Keyboard and gamepad shortcuts (coin, start, reset, turbo, save/load)
• Auto-update on the Windows installer

1. Download the version for your device from the link below
2. Put your games in Documents/EmulatorJS/roms, one subfolder per system (for example roms/snes, roms/fbneo), or pick other folders in "⚙ Folder settings" (RetroArch's usual folders are found automatically)
3. Some systems need BIOS files (for example Sega CD); put them in Documents/EmulatorJS/system
4. To play over the internet, enter the address and room password of a play server under "Internet play server" (see the "Internet play setup" screenshot); on the same Wi-Fi nothing needs to be set

There is no central server: for internet play, you or one of your friends hosts a small play server, and only people with its room password can see and join your games.

1. Rent the smallest cloud server running Ubuntu 22.04 or 24.04
2. In the cloud console's firewall, open TCP 8765, TCP 80, TCP 3478, UDP 3478 and UDP 49160-49250
3. Upload ejs-cloud-setup.sh (on the download page, and in the cloud-server folder of the folder version) and run: sudo bash ejs-cloud-setup.sh
4. When it finishes, it shows the server address (https://...) and the room password. Enter them under "Internet play server" on every device

The script sets up everything by itself: a free HTTPS certificate that renews automatically, a relay for strict home networks (TURN), and an admin menu (sudo ejs-admin) for accounts and server limits. If you have a domain, run sudo bash ejs-cloud-setup.sh yourdomain instead. To update the server later, upload the new script and run it again.

• N64, PSP and Saturn need a reasonably fast device
• Online play is input-sync, so everyone needs the same game file
• The apps aren't code-signed, so Windows SmartScreen and macOS Gatekeeper warn on the first launch (on Mac: System Settings → Privacy & Security → Open Anyway)

Feedback and bug reports are very welcome, especially on how online play works across different countries and networks, and how the touch controls feel on your phone.
