sys-patch released, a system module that automatically patches the Switch on boot
Today, another great homebrew has been released for the Nintendo Switch, in the form of sys-patch by @TotalJustice.
sys-patch is a sysmodule that runs on your Switch at boot, and automatically patches both the Switch's firmware's FS and ES, and also Atmosphere's Loader to basically give the same effect as what the long-running signature patches do for the system, without having to rely on the actual signature patches files being present on the SD card.
This sysmodule comes with the great benefit of relying on very little maintenance or updating, since it does the patching automatically without relying on file hashes like the actual IPS patches do, and instead relies on actual code/data patterns to patch, making this future proof to an extent, unless a specific firmware or Atmosphere update changes some of this data. TotalJustice explains it as follows:
TotalJustice said:The benefit of sys-patch is that it only needs updating when something major breaks, the last time this happened was fw 15.0.0.
Another benefit is patching ldr will (likely) never need to be updated. In the past, of a silent atmosphere update happened, this would break sigpatches (unless you updated them again).
sys-patch also outputs a log where you can see which patches are applied, which one failed and some other useful data. You can manually read the log or use the overlay, which you can also use to change the config.
TotalJustice also recommends that, despite the current features and abilities of sys-patch, to not take it as a complete replacement for the sigpatches yet, since those can still be used as a fallback in case some updates do break compatibility with sys-patch (until it is properly updated).
