Hacking Sigpatches for Atmosphere (Hekate, fss0, fusee & package3)

[Krazyeye]

I recently updated CFW to 20.3.0 and atmosphere to 1.9.3 via HATS Pack, included sys-patch as of this post

But my games that previously ran won't run anymore saying the software was closed due to an error.

if you're using sys-patch, you need to reboot your switch if you haven't.

I've rebooted.

Hello Kitty Island Adventure which didn't run on 16.0.1 is now running but every other game that previously ran is not working anymore. Tried to download from another souce also but no success

Hello, I recently updated my emunand from fw 19.0 to 20.3.0 via daybreak. I also installed atmosphere 1.9.3 and sys-patch 1.5.6 via HATS pack. Hekate is latest at 6.3.1.

After all the updates, atmosphere loads and everything looks fine, but none of my games work anymore. Whenever I try opening them, it initially loads but later on says software closed due to an error.

In an effort to trace what's wrong, I noticed that "noncasigchk_new" shows as unpatched. Everything else is showing patched in the log.

Some are showing as patched in yellow because I'm guessing it's due to sigpatches...

The #1 post states that there is a sig patch for 20.4.0, but the sig patch file name is still 20.3.0.
Is it because they are using the sig patch or the file has not been updated?

Modules not updated in 20.4.0

impeeza explained what he could about the new firmware and the old sigpatches here. Still, wait for the Atmosphere and Hekate to be updated, if necessary.

hekate 6.3.1 states that it supports 20.4.0

Yes because no important modules changed so no need to upgrade code, atmsphère have a safe measure to avoid run on a new firmware to avoid damage, so code must be updated to allow new version.

When starting Atmosphere 1.9.3 with 20.4.0 it freezes on a black screen

Atmosphère 1.9.3 DO NOT SUPPORT firmware 20.4.0 you need to wait for a updated version or search the unofficial version of Zoria.

But as you prove you are unable to read I recommend you to wait for full support of the firmware.

 

[LuigiGad]

unofficial version of Zoria.

Searching, I then found the dirty version but at least it works, on some Japanese sites they have also published the new versions mentioning the resolution of the energy bug, is there any information about it?

Happy June 15th

Can anyone help me? I recently updated my system to 20.1.1 atm 1.9.4e, and the games stopped working. As I understand it, I need to download some files, but I can't find the ones that would work for me.

What did nintendo customer service tell you? Email them your serial number and what game is wrong.
Or try install new syspatch first.

Hello everyone, when using the sigpatches I have success with most games.

However I noticed issues in these 3 games:

1) Breath of the wild (game does not start - update prompt)
2) FE: Three Houses (does not install with gold leaf due to sigpatch error - tested and runs successfully in emulator)
3) Two Point Hospital (does not install with gold leaf due to sigpatch error)

Are these known issues or am I doing something wrong?

I'm on atmos 1.9.1, FW 19.0.1, running the latest sigpatches available

Install them from another dump, and install them using Sphaira.
if you have any mod, remove it before install a new version.

Hello Naivegirl2411,

Breath of The Wild problem, if it is up to date, is due to 19.0.1. Once you update to the latest FW, it will work perectly again!

Best regards
