About a month ago, user @Reisyukaku, the creator of ReiNand on the 3DS, teased that they were in the process of making their new custom firmware. What we initially saw was just a custom splash screen. Now, they've publicly released the highly awaited ReiNX CFW for the Nintendo Switch.

Rei states that this is a simple, modular CFW, and that everything works together independently. They'll also be working on a custom sysmodule for ReiNX, as well. You can check it out and compile it yourself at the GitHub link below.

The modular switch custom firmware

Usage:

Put ReiNX folder on the root of your switch's SD card and run ReiNX.bin with your favorite fusee launcher.

Compiling:

You'll need devkitpro with devkitA64 and run make

Features:

• Loads all KIPs from /ReiNX/sysmodules/ directory
  
  
• Optional custom kernel/secmon/warmboot
  
  
• Default kips with exefs redir from /ReiNX/title/{tid}

Are you saying what I think you're saying... No reason to buy SX OS now? It runs backups?

too good to be true :Þ

 

[gnmmarechal]

Does that mean installing .nsp files and running them is possible now?

Uh, think so. I am almost certain that one I uploaded has sigpatches.

I'm dreaming but if it does I'll be forever grateful and amazed

I will wait and see for someone who knows what they're doing to try it out

errrrr....
any volunteer?

Pretty sure sigpatches work now. Here's what I compiled a few hours ago.

It's untested.

So just drop on root and run payload?

You're not the hero we deserved, but the hero we needed.

 

[soussi]

i m still on sx os so not gonna try some builds out not fixing stuff that aint broken

 

[Ian095]

I'm going to assume it doesn't work since nobody is bragging about it

erm, I'm pretty sure it does. People have been saying so on the discord server.

Nice!!! I might try it then I'm not in any of the discord servers. Guessing I just need NSP format files to install then?

This does not include signature patches. This is the one that does:

Edit: URL removed because it's out of date, and people are still downloading it for some reason. A fork of Hekate has native support for signature patches now, and you can use them in conjunction with LayeredFS for DevMenu (or any other CFW).

So, after reading latest comment, i understand that sig patch allows us to run program unapproved by Nintendo (if thats what unsigned programs means)
but what can we now?
As in, whats released so far?
emulator?
backup loader?
homebrew launcher?

From what I understand you're just installing the eshop version of a game unofficially. XCI backups won't play any part in this.

[Ian095]

xci?

There's XCI which is basically just a rom and there is NSP which don't quote me on this is just an installer package which originates from the eshop. XCI backups are used with SX OS meanwhile Devmenu (a developer program from the Nintendo Switch) is capable of installing NSP file formats. I believe Rei has programmed his own NSP installer into his CFW. I've not tried running it but it can do everything to do with the Homebrew Channel + install games for free. I'm not super experienced but from what everyone is saying that's what it sounds like.

Great work. There is much progress so far. I got to get me a second switch just fo the hacks being developed and before the current hackable switch become $900.... So much for Xecuter SX being future proof. Future proof means not even a hardware revision makes it obsolete...

Wouldn't it be amazing if a team rewrote Nintendo's switch operating system and then loaded that instead of the official os. I'm talking not just custom firmware but a full OS running on custom OS. then you can stop the system from logging as you have full control over the OS. Any feature Nintendo uses to check for bans would be rendered useless as the custom OS would just fake a pass.

Rewriting the entire OS is no small task. Its a lot easier the just load the official os with memory patches then rewrite it. I'm sure not enough information about the switch is know to undertake such a task. If it was achieved then kiss the bans good buy.

okok isee
thanks

The last thing to keep in mind is hypothetically speaking if you installed NSP packages and went online there's probably a 100% chance you'd get banned. I'm not 100% certain but it seems like common sense.
