DVR-Patches is a collection of exefs patches that enables streaming incompatible games using SysDVR.

This is experimental and has not been extensively testedc use at your own risk: may not work at all, cause instability and crashes or degrade performances.

While it is unlikely that this can get you banned but again, use at your own risk.

Installation

Patches are bundled in a zip file ready for Atmosphere, just extract the dvr-patches.zip file to the root of your SD card. Reboot your console. Now streaming should just work.

Every time you install a new firmware update you'll probably need to download a new version of these patches which may not be available right away, check the commit messages to know when support for a new firmware is added.

User guide

What does it do

The Nintendo Switch has a build-in record function that can capture a short video of your gameplay, however there are some games such as Smash & Paladins, that does not allow you to record the last 30 seconds of gameplay.

With these patches, it becomes possible to record the last 30 seconds of games that are not typically supported. The quality is capped at 720p 30fps. However, if you overclock the system, you can record 60fps replays.

Game compatibility

Most games seem to work fine, a few have been reported to not work or crash, check out the issues page for a list.

If you get a crash with title id 0100000000000023 it's most likely because of this.

Technical stuff

What do these patches do?

Currently only the AM sysmodule is patched, the following changes are made:

• All games that don't support recording will behave as if they have auto recording enabled in the nacp.
• All games will have screenshots enabled in the nacp.
• Am's code flow is adjusted to avoid crashing when memory allocation for auto recording fails.
• The function to block recording in certain sections of the game is stubbed .
• As a nice bonus, the function games use to load an overlay image is stubbed.

If you want to port these patches to different firmware versions, check out porting notes.

Compatibility

All firmwares starting from 11.0 should be supported, however patches must be updated with new firmwares.

You can check if the latest firmware is supported in the releases tab or enable GitHub notifications for this repo to get notified of updates.

Sometimes firmware updates don't need new patches, for example 14.0 uses the same ones as 14.1 because the relevant system module (am) was not changed, before opening an issue when a new firmware releases try running the patches.
