Bug

- Is not possible to create NSP forwards (Signature Fake warning appears)

Games and homebrew install fine; this only happens with NSP forwards.

dbi doesn't create forwarder, there is tool out there to create forwarder if you want to create them.

Hi all, I am a noob and I just received this Switch running CFW on sysMMC (modchip, no emuMMC) — Atmosphere 1.11.2 on firmware 18.0.0. DBI is updated to the latest release and installs work fine for signature checks in general, but any unsigned NSP/XCI install fails because the console still enforces official signatures.

I understand I need sigpatches (es_patches, possibly fs_patches) matching this exact Atmosphere/HOS version, but every source I've tried is either outdated, dead, or clearly not matching 1.11.2/18.0.0.

Could someone point me to the sigpatches package for this exact version? Thanks

why are you posting this in this thread?
your issue isn't with patches, go talk to developer of the homebrew you are using

Using syspatch this doesn't happen and nsp forwards works fine

Does it work on 22.5.0?

 

[Marlboro_]

Sigpatches are backwards compatible, just get the latest if you need them. I'd suggest switching to sys-patch instead as it's much more reliable and you don't have to update it every time new firmware and/or Atmosphere gets released.

After months i finally managed to repair my switch by installing sys-patch. Thank you!

Could you please share version 22.5.0?

Thank you so much @bth for continuing to provide these. I get syspatch is the future, but as a busy dad with limited time it's nice that for now I can continue to use the upgrade method I've leveraged for years with the latest sigpatches until I get time to move over & read up on syspatch.

Well I was trying to use the 22.5.0 sigpatches but I have several games that won't open. I get "An error has occurred", but only on certain games, mostly older, which is weird. Anyway, so I'm gonna finally get around to installing sys-patch. I have a couple of questions:

1. Do I just drop the files onto my SD card?
2. Do I need to get overlays working first?
3. Is Ultrahand/nx-ovlloader the combo I need for overlays?

Thanks in advance to whoever reads this. I just updated my switch from firmware 17 so I'm trying to get caught up. I swear I had tesla overlays working before but this was before Ultrahand and the button combo isn't opening the overlay menu so I guess I missed it when rebuilding my SD Card at some point.

1. Do I just drop the files onto my SD card?

Yes.

2. Do I need to get overlays working first?

No, but know that Ultrahand and Tesla menu use different combos to bring up the overlays. For Ultrahand it's ZL + ZR + DDOWN.

3. Is Ultrahand/nx-ovlloader the combo I need for overlays?

When you download Ultrahand ZIP file, it already has nx-ovlloader included. Download nx-ovlloader only if it's newer and confirmed as working properly.
