Guide

You'll need a console running Atmosphère CFW and the homebrew menu.

1. Download GMCA.nro from the latest release and copy it to sdmc:/switch/.
2. Launch GMCA from the homebrew menu.
3. On first launch in applet mode, GMCA offers to install a HOME menu tile: press the button, confirm, and the app relaunches as a regular title with full memory. Alternatively, hold R while launching any game (title takeover).
4. Add your media server (see Connect a server) and start watching.

Coming from pleNx? GMCA reads your existing library, logins and downloads automatically on first launch, nothing to re-configure.

Every release ships builds for all supported platforms, with fresh nightly artifacts on nightly.link.

PS Vita

Install GMCA.vpk with VitaShell, or find GMCA on VitaDB, for jailbroken consoles.

Raspberry Pi / Linux

Flatpak bundles for x86_64 and arm64v8 (OpenGL 3), plus an Arch package. Wire a Pi to the TV with a controller or keyboard for a full 10-foot media center.

macOS

DMG for Intel and Apple Silicon, macOS 10.15+. If Gatekeeper refuses to open the app, clear the quarantine attribute:

sudo xattr -rd com.apple.quarantine /Applications/GMCA.app

Windows

Portable 7z archives for x64, x86 and ARM64 (Windows 7 or later, DirectX 11.1).

On first launch, pick a backend. The same interface follows whichever you choose.

Plex

Enter the 4-character code shown on screen at plex.tv/link, then pick your server and your Plex Home profile (PIN-protected profiles supported).

Jellyfin / Emby

Type your server URL, then authenticate with Quick Connect (no keyboard) or your username and password.

Stremio

Log in with your Stremio account. Your add-on catalogues and library sync across your devices. Streams play from direct links or your configured debrid service.

File servers

Add a WebDAV, FTP, SFTP or HTTP(S) share straight from the UI, with a connection test before saving. USB drives work too on Switch.

Gamepad	Keyboard	Action
A	space	Play / Pause
B	esc	Stop
Y	o	Toggle OSD
X	f4	Menu
R / L	] / [	Seek forward / back
+	f1	Video profile
RS	f2	Video quality
LS	f3	Playback speed

Anywhere in the app, press X (or long-press) on a poster to open the quick actions panel: go to show, go to season, mark watched, download, add to your list.

• Nintendo Switch:Atmosphère CFW, full-memory mode for playback
• PS Vita:HENkaku/h-encore jailbreak
• Raspberry Pi / Linux:Flatpak (x86_64 / arm64v8), OpenGL 3 support
• Windows:Windows 7 or later, DirectX 11.1 support
• macOS:10.15 or later, Intel or Apple Silicon

MPV decodes H.264, H.265, VP8, VP9 and AV1 video; Opus, FLAC, MP3, AAC, AC-3, E-AC-3, TrueHD and DTS audio; and SRT, VTT, SSA/ASS and DVDSUB subtitles. Anything your hardware can't direct-play, a Plex/Jellyfin/Emby server transcodes.

Is this pleNx? What happened to it?

GMCA is the evolution of pleNx: same app and team, renamed as it grew from a Plex-only client into a multi-backend one (Plex, Jellyfin, Emby, Stremio). Existing pleNx installs migrate their data to GMCA automatically on first launch.

Subtitles don't show up on Switch?

Drop any TrueType font at sdmc:/switch/GMCA/subfont.ttf; it will be used to render text subtitles.

macOS won't open the app?

Gatekeeper quarantines unsigned apps downloaded from the internet. Clear the attribute:

sudo xattr -rd com.apple.quarantine /Applications/GMCA.app

How do I enable an external USB drive on Switch?

Set ums in config.json (in sdmc:/switch/GMCA/):

{
  "setting": {
    "ums": true
  }
}

Is GMCA affiliated with Plex, Jellyfin, Emby or Stremio?

No. GMCA is an independent, open-source, third-party client, not affiliated with or endorsed by any of them. It talks to your server with your own account.

Where do I report a bug?

On the GitHub issue tracker. Describe what you did, what happened, your backend, and your device model. On desktop, launching the app with -d -o gmca.log writes a debug log you can attach.
