The SysDVR Settings app is the on-console control panel that comes with the full version of SysDVR. It’s where you see whether the sysmodule is running, check which streaming mode is active, and switch modes — no SD card removal, no config files. You’ll find it in the Homebrew Menu after installing the full build from the download page.
One thing to know before you judge it broken: the full build of SysDVR starts about 20 seconds after the console boots. If the Settings app says SysDVR isn’t running immediately after power-on, wait half a minute and open it again — that delay is normal, and it’s the single most common false alarm with this app.
The options at a glance
| Option | What it does |
|---|---|
| Current mode display | Shows which streaming mode the sysmodule is using right now. |
| Switch streaming mode | Changes between Simple Network, TCP Bridge and USB — takes effect without reinstalling anything. |
| Go Offline | Takes the sysmodule offline and stops streaming without uninstalling or deleting anything. |
| Version display | Shows the installed SysDVR version, and warns you when it is outdated. |
| Icon cache cleanup | Clears the cached game icons the app has stored, so stale or wrong icons are refreshed. |
The three streaming modes
Simple Network — the default
Every fresh install starts in Simple Network mode. The console runs an RTSP server and any compatible video player can connect to rtsp://<console IP>:6666/ — no SysDVR-Client required. It’s the quickest way to get a picture on a phone or TV, at the cost of more buffering. Our Simple Network (RTSP) mode guide covers the low-latency player settings.
TCP Bridge — the recommended network mode
TCP Bridge streams through SysDVR-Client with low latency and automatic console discovery on your local network. If you watch over Wi-Fi or LAN, this is the mode to live in — see the TCP Bridge mode guide for setup and the manual-IP fallback.
USB — the lowest latency
USB mode streams over a cable and is the lowest-latency option, which is why it’s the playing mode of choice for a laptop setup. It does not work while the console is docked, and Windows needs a one-time driver install from inside the client. The USB streaming walkthrough has the full procedure.
Go Offline — pausing SysDVR without removing it
Go Offline stops the sysmodule from streaming while leaving everything installed. Since SysDVR 6.2.1 the sysmodule can be started and stopped from the Settings app without rebooting the console, so this is a quick toggle rather than a teardown. It’s the option to use when you want the console to behave like stock for a while — for example, when another USB homebrew tool needs the USB interface that SysDVR’s USB mode is holding. Switch the mode away from USB, or go offline, and the interface is free again.
Version display — and the “outdated” warning
The Settings app shows the SysDVR version installed on the console. It will also tell you the sysmodule is outdated when the files on the SD card are newer than the version actually running — which almost always means one thing: you copied new files but didn’t reboot. Sysmodules are loaded at boot, so after every update the console must restart before the new version is live. Our guide to updating SysDVR walks through the full both-sides process.
Icon cache cleanup
The housekeeping entry in the list: it clears the cache of game icons the app has stored. If game icons ever look stale or wrong, clearing the cache forces them to be fetched fresh. You won’t need it in normal use — it’s there for when things look off.
No Settings app at all? You’re on the USB-Only build
The lightweight USB-Only build has no Settings app — that’s by design. It streams over USB only, uses roughly half the memory of the full build (~500 KB), and there are no modes to switch. The few toggles that exist for SysDVR live as files in the /config/sysdvr/ folder on the SD card instead — the advanced tips guide explains the no_adv discovery switch that lives there. If you want modes, recording-friendly flexibility and this Settings app, install the full build instead, as covered in the install guide.
When Settings says “not running” or “outdated”
- Just booted? Wait ~20 seconds and reopen the app — the sysmodule is probably still starting.
- Just updated? Reboot the console; the running sysmodule is still the old version until you do.
- USB-Only build? The app will never connect — it isn’t supported on that build at all.
- Still stuck? Work through the dedicated fixes in “SysDVR is not running / outdated” — every fix.
Starting and stopping SysDVR without a reboot
One quieter feature lives in the same app: since SysDVR 6.2.1, the sysmodule can be started and stopped from the Settings app (via its toolbox integration) without rebooting the console. Combined with Go Offline, that means “SysDVR is installed but completely quiet right now” is a state you can reach in seconds — and reverse just as fast when you want to stream again.
If the Settings app itself is missing
The app ships inside SysDVR.zip as switch/SysDVR-conf.nro. If you installed the sysmodule but can’t find the app in the Homebrew Menu, that file almost certainly didn’t make it to the card — re-extract the full zip to the SD root (as in the install guide) and it will appear. And if you’re on the USB-Only build, remember the app isn’t missing — it was never part of that build.
