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(es_patches, possibly fs_patches) matching this exact Atmosphere/HOS version, but every source I've tried is either outdated, dead, or clearly not matching 1.11.2/18.0.0.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

 

[Blythe93]

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.

Thank you so much for your response!! Gonna get it all updated tonight then. I've wanted overlays for a bit anyway, so I meant to do that either way.

EDIT - Sys-patch fixed everything

hey so bit of a noob here, haven't updated the switch and i want to update it to the latest version, but i got a few questions:

1) is it safe to update to the latest version?
2) when i update (this has happened in the past) usually games no longer boot, how do i combat this on the latest version?
3) since sigpatches are no longer used, is it safe to delete them and replace them for the sys-patches?

 

[Blythe93]

1) is it safe to update to the latest version?

It should be provided that the homebrew apps you usually use got updated as well. For unofficial updates, check here.

2) when i update (this has happened in the past) usually games no longer boot, how do i combat this on the latest version?

Make sure that you have the latest sigpatches. I'd suggest using sys-patch instead of sigpatches or this fork of the Atmosphere with the up-to-date patches built-in.

3) since sigpatches are no longer used, is it safe to delete them and replace them for the sys-patches?

Yep, or use the previously mentioned Atmosphere fork with the built-in patches. In that case you don't need sys-patch either.

In any case, check this guide:

ONLY UPDATE YOUR CONSOLE TO 2x.x.x IF ALL THE HOMEBREW YOU USE IS UPGRADED

Sometimes you need to upgrade your console, upgrade the firmware or upgrade Atmosphère, using the @l7777 's guide (https://gbatemp.net/threads/updating-hekate-atmosphere-and-hos.631739/) as base I hope to create a list of necessary steps to successful upgrade your console.

This guide uses Hekate, if you don't want to use Hekate skip the steps about it. You may loose some features.

Is there any other source for sys-patches? for some reason the page is blocked by one of my extensions...

it's on github only, use a vpn or different browser if you are being blocked from visiting github.com

Impeeza posted this one here on GBAtemp, should be the same one.

hey sorry, so still new to all of this and such. Turns out I can access github just fine and all if i disable the extension

if i grab this fork of atmosphere instead of the official one, does it still support the latest firmware version of NX1? (If I recall, it was like 22.5.0, right?) and i don't have to grab the sys-patches

Yes and yes. bth is actually the mastermind behind that fork and the sys-patch and so far he's been pretty quick to release the updates whenever they were necessary.
