Welp, I might as well do my own write-up of the steps if everyone else is:

How To Install Palantine CFW
-----------------------------------------------------------
Requirements:
1) 4.5.0 or lower firmware Nintendo 3DS/XL/LL console with a 2GB or larger internal SD card
2) A DS mode Flashcart, like the DSTWO
3) Windows Vista or a newer version of Windows
4) These files:

5) Gateway's latest Launcher.dat (Google it, as we can't link it here)
6) For installing anything, you'll need the DevMenu.cia (you can get if from Govanify's CFW package hosted on his site, if you're brave enough to trek there)
7) Patience and a working brain
Step 1)
Before you do anything, you need to set up your 3DS network settings so it can connect to your network successfully with a static IP. To do this, follow the picture guide I've laid out on imgur (to save space in this guide, of course).

Step 2)
You're going to need a DS-Mode flashcart to continue from here on out.

Download the files package from the link further up in this thread, and extract it using WinRAR.
Inside this package, I've included everything I legally can to get you set up.
This includes:
- Palantine CFW 1.0
- EmuNAND Tool 1.0.1
(note, this may be detected as a virus by your antivirus software. I can assure you that it isn't, but you can do this manually with a hex editor of your choice if you are too skeptical of using this software. Many on this forum use it, so if it was a virus, it would have been removed long ago.)
- EmuNAND to CFW-NAND batch file
- ROP Multi-loader
- blank database files
From the archive, open "EmuNAND Setup", and in there, locate "For DS Flashcart".
You'll find the file "rop_multiloader.nds" in there. Copy that file to the root of your DS Flashcart's MicroSD card. Then, put that MicroSD card into your DS Flashcart, insert it into your 3DS, and start it up. From the flashcart's menu, browse to the root of your MicroSD card and launch the "rop_multiloader.nds" file. In here, select "Gateway 4x" and then press the home button when it finishes.
Step 3)
Pull the big SD card from your 3DS and put it into your computer. You now need the Gateway 3DS launcher, which you can acquire from the downloads section of their website.
Before you continue, I recommend backing up all of the contents of your big SD card. This next step will, unfortunately, cause all data on the big SD to be lost otherwise.
Locate the "Launcher.dat" within the Gateway firmware package and copy it to the root of the big SD card. Next, insert the big SD card back into your 3DS.
You can now start the MSET profile exploit. To do this, open the system settings app, go to "Other Settings", then open "Profile", and follow that with holding down the "L" bumper, located on the back, left hand side of your 3DS (from the front of the unit). While continuing to hold the "L" bumper, with your other hand, open the "Nintendo DS Profile". This will trigger the exploit, and open the Gateway configuration menu. In here, you're going to want to first make a NAND backup. I'd advise that you plug in your 3DS to a power source from here on out. To do this, use the D-Pad of your 3DS to go over to "BACKUP SYSTEM NAND", then press the "A" button on that, and when the next menu comes up, press the "Start" button. This will give you a complete NAND backup, so if something goes wrong, you can have it restored to that backup at any time through the use of a hardware eMMC NAND programmer. Once that backup has completed, just hold the power button on your console until it turns off, and remove the big SD card. Put the big SD card into your computer and copy the "NAND.bin" file off of the big SD card, and put the backup in a safe place.
Next, start up the Gateway menu the same way as before, but this time, go all the way over to the option that says "FORMAT EMUNAND". Press the "A" button on this option, and when it loads up, press the "Start" button. This will take some time to complete, about as much as the original NAND backup, so go take a break while your 3DS does it's work. Once it's done, hold the power button until it turns off again, and you'll be ready for the next step.
Step 4)
Take the big SD card out of your 3DS again, and put it in to your computer. You're going to need to use EmuNAND Tool 1.0.1 now, so, although it pains me to say this, but if you have an antivirus software that isn't fond of this program, you will need to disable it until we're done this step.
Start up EmuNAND tool, and, with your big SD still plugged in, click on the "Extract emuNAND" button. Direct the emuNAND tool to the "EmuNAND Setup" folder of the extracted archive included in this tutorial, and save the backup as "EmuNAND.bin". Next, once it has completed, drag and drop the EmuNAND.bin file you created onto the "drag_emunand_here.bat", and wait for it to finish. It will create a CFW_NAND.bin for you to work with. Once it's done generating the CFW_NAND.bin, go back into EmuNAND Tool 1.0.1 and click on the "Inject NAND to emuNAND" button, and open the CFW_NAND.bin file that was created. This will take some time as well. Once it's complete, remove and reinsert your big SD card into your computer, and then open it again. You'll notice that you have no data there, except for a "LAUNCHER.DAT" file, left by the Gateway EmuNAND creator tool. You can delete this now, as you will no longer need it.
Step 5)
take your big SD out of your computer, and put it back into your 3DS. Power on your 3DS and accept the prompt for the 3DS to create new SD card data. If it prompts you to update, of course, cancel the update and never accept it. If you do, you'll have to put that NAND.bin backup you made earlier to use in order to restore the console to a working/exploitable condition.
Once the 3DS finishes making the SD card data, remove it from the 3DS once more and put it into your computer. You should now find a "Nintendo 3DS" folder on your big SD. Open it, and open the two subsequent folders that are inside that folder. They will have seemingly randomized names, but they are part of your console's ID numbers. As a result, they will be different for everyone.
This folder should be empty, or it might have the following folders in it:
- dbs
- exdata
- title
Any folders that are missing of these three, I recommend you create. The priority one, however, is the "dbs" folder. Create it if it doesn't yet exist. Open it, and delete anything inside it if there is anything. There shouldn't be, so you will not have to do this most likely. Navigate to the included archive for this tutorial, and open up the "Database Files" folder. Inside this folder, you'll find two files. They are "import.db" and "title.db". copy both of them to your big SD card's "dbs" folder. Now put the big SD card back into your 3DS.
Step 6)
Open the "System Settings" app again, and navigate to "Data Management", in there, open "Nintendo 3DS", and then open "Software". This should launch a prompt that says "The SD Card software management information is corrupted. Reset it now? This will delete all software and save data.".
Select "Reset", and wait for it to complete.
Now, take your big SD card out of the 3DS once more, and insert it into your computer. Navigate to the included archive for this tutorial and open the "SD Card" folder. Copy all of the files in here to the root of the big SD card except for "Launcher.dat". Once copied, rename the "Launcher_GW.dat" to "Launcher.dat" on the big SD card. Finally, put the big SD card back onto your 3DS. You can now launch the custom firmware.
Step 7)
This CFW is yet buggy, so it may not actually start the first time... or the third... or the seventh. Don't worry, it will start eventually, but it can take a good number of tries. To get started, with your big SD card inside your 3DS console and your console powered on, open the "System Settings" app again. Now, open "Other Settings", then "Profile", and then, while holding down the "L" bumper like before, open the "Nintendo DS Profile". This may result in one of three situations.
1) The top screen turns blue, and the bottom screen goes from black, to white, and back to black again.
- This means it worked, and the custom firmware will launch in a moment.
2) The top screen turns blue, and the bottom screen goes black, nothing happens after this.
- This means something went wrong with the exploit, and you'll need to try again. Hold the power button until the 3DS shuts off, then turn it back on, and follow from the start of Step 7 again.

If you got the CFW to start, congratulations, on to the next step!
Step 8)
Open the archive included with this tutorial again, and in there, you'll find at the root, a batch file named "run.bat". Right-click it, and select "Edit". It should now open in Notepad. At the part where it says "192.168.2.237", replace that with the static IP address you assigned to your 3DS console during Step 1. As mine was "192.168.2.237", I have left that in there for those who decided to use the same IP. Now, simply click on the "File" drop-down menu and click on "Save". You can now close the Notepad window.
To install, for example, the DevMenu.cia that you, for example, acquired from Govanify's CFW package on his website, simply rename the .cia file to "ciatoinstall.cia" and make sure it is in the same folder as the "run.bat" file. Now, with the 3DS running the CFW and your computer ready, run the "run.bat" file and wait for the installer to complete. You want it to return an "error code index 0", which means that it worked. Next, press the power button on your 3DS. Don't power the console off, just wait for the power off menu to open, and then press the "Home" button on your 3DS to re-load the home menu. A new Present should appear on your home screen. Open it, and you'll find the application has been installed successfully.
If you've converted a game into a .cia file, you'll find that only games with a correctly formatted .rsf file will properly launch from here though, and do not have firmware dependencies from higher than firmware 4.5.0.
You can install CIA files over your network, or through the DevMenu, if you install it.
Thus concludes the CFW installation guide, I hope this helps some of you out, and I'll try to update it as new developments come about.
