ROM Hack Question How can I retrieve saves from a Nand backup? (SX Core)

[Nerdtendo]

I had a Switch that broke a while back. I'm in the middle of backing up the nand by plugging the chip into my SX Core-enabled Mariko unit. I had some save files that I would like to recover. I know that HacDiskMount is usually used to mount Nand backups and operating on them, but can this be used without the actual title keys? I can't use tools like Lockpick or biskeydump on my unit. I know I have a key backup somewhere from before I installed CFW on the original Switch. Could I use those in conjunction with my new Nand backup?

Title keys aren't used for decrypting save files...

No but they are used to use hacdiskmount. I figured it out on my own in the end though
