Please don't use any Gateway guides for installing a9lh, they are outdated and dangerous.
Follow https://3ds.guide in its entirety (except keep your emuNAND, don't follow the "Move emuNAND" section, don't tick "Autoboot sysNAND" in Luma settings, and double check your firmware starts with "Emu" not "Sys" or "Ver", before doing anything further, and don't update your system near the end like it tells you to).
Then follow https://gbatemp.net/threads/tutorial-using-luma3ds-with-gateway-on-v2-a9lh.431691/
Then, go into Gateway mode and update your emuNAND with a rom of Yoshi's Wooly World (you'll have to turn off rom update blocking from the Gateway menu).
Then, you're safe to play your console.
I'd recommend also updating your sysNAND to 10.3 using a firmware pack from "that" ISO site and sysupdater. This avoids problems with save encryption arising from having a sysNAND below 7.x and an emuNAND above 7.x. You can enter sysNAND by ticking the "Autoboot sysNAND" option in Luma settings. For the love of God please do not enter sysNAND in Gateway mode!

And, above all else, make NAND backups and keep them somewhere safe.

 

Try this URL to load Gateway: http://go.gateway-3ds.com/old/
Or you can install A9LH first, and use this guide: https://gbatemp.net/threads/tutorial-using-luma3ds-with-gateway-on-v2-a9lh.431691/
to get into Gateway and do what you need to do.

 

Unfortunately the Old Gateway url didn't work either. It took me to the page but never crashed out to load Gateway like it's supposed to. Yes, i could install Luma al9h first, but i don't see how that would help me install Gateway.

You think this might be because I'm on 6.1.0-4U and using Gateway 3.7.1 Ultra Beta which has a launcher for newer versions of Emunand? I tried on 3.4.1 as well but that didn't work either. I think maybe i should try even older versions, but sadly they are no longer available on Gateway's website.

Unfortunately that link didn't work for me....and my saves are inside the roms of my Red Card. If i had them backed up on my computer it might not be such a problem, but i need to access Gateway Emunand to have the Red Card recognized, so then i can use SaveDataFiler to export them.

 

If you install A9LH first, you can use Gateway's A9LH payload. Check the tutorial I posted on it

 

You can leave your sysNAND as is. Just use emuNAND as your main NAND (don't enable "Autoboot sysNAND" in luma config)
If you want to use Gateway, the max version you can update emuNAND to is 11.2. You can update to that version by using a ROM with 11.2 on it (Poochy & Yoshi's Woolly World) and boot Gateway Mode while holding D-Pad Up to disable update blocking. Make sure you're in emuNAND before updating! (check the MultiROM menu)

 

Thanks! Btw would i need a cartridge of Poochy & Yoshi's Woolly World or would a CIA suffice?

 

They do if they were converted from 3ds without stripping them out. I think that's where they come from. I have several. Not sure if it does anything, but it's in there.
Edit: Either that or I'm remembering 3ds with updates in them. It's been a while since I was messing around with mods.

 

But i would be installing that .3ds rom as a CIA wouldn't I?

 

Yeah, I didn't think it did anything other than taking up space inside a CIA if it's even in there. I couldn't find some CIA versions of games so I ended up using cart dumps for a bunch of things and now I can't remember what was inside what.

 

I did initially try the latest version, and when that didn't work i figured that since I'm on such an old OFW maybe an older version of Gateway Launcher would.
