Homebrew Others Help Managing Multiple Mario Kart 8 Deluxe Updates on FAT32 SD (No exFAT)

Hey all,


I'm trying to set up multiple update versions of Mario Kart 8 Deluxe on my modded Switch so I can easily switch between them depending on which cheats/mods I'm using.


Here’s what I’m trying to do:

• Store multiple MK8DX update NSPs (e.g., 3.0.1, 3.0.2, 3.0.3) on my SD card
• Use DBI to install/uninstall whichever update I need
• Keep them organized in folders like:
  /switch/updates/mariokart/3.0.1/
  /switch/updates/mariokart/3.0.3/
  

The problem:
My SD card is formatted as FAT32 (for compatibility with other tools), and some of the update NSPs are over 4 GB, so I get errors trying to copy them onto the card.


I do not want to reformat to exFAT.

What I’ve tried so far:​

• Using DBI’s MTP Responder to install directly — works, but it overwrites the old update, and I can’t keep multiple NSPs stored on the SD this way.
• I read about splitting NSPs into .nsp.00/.01 parts for FAT32, but I'm not totally sure how to do it cleanly.
• I’m using DBI to browse and install NSPs from the SD card directly.

---

What I need help with:​

• What’s the best way to split large NSP update files so they can be stored on FAT32 and still install fine through DBI?
• Can someone walk me through using NSC_Builder or another method to split properly?
• Any other tips for managing multiple update versions cleanly like this on a FAT32 setup?

Thanks in advance!

You can only install one update version at a time, so doesn't matter if you keep multiple versions.

The easiest way is to install the update, dump it to your sd card. Install the next update, dump it etc. That will automatically split the update for you. You can use DBI for the installing and dumping.

There are pc tools that will split the files for you, but the above is probably the easiest as it will just work (tm).

alright so i did install a new update via DBI's mtp responder but when i go to view the contents of the game it just shows one update. if you are talking about a different dump method thru DBI can you pls tell me?

You could if you want but you need to format to exfat if the files is larger than 4gb, ideally not convenient since you are on fat32.

Just buy usb c flash drive and put your files in there, and install with tinwoo.

Yeah that's why I was wondering if there are other methods

Wait, I can put the c drive in my switch and it will read the files on it?

This is your answer but you have to use the tool to dump and install the various updates when you want to switch versions.

Doesn't simple mod manager meet these requirements? I have two different mods on mine i can switch between at will as well as my own kart mods.

Can't ask for warez. No one here is going to tell you where. You just gotta keep searching

Think there's a misunderstanding, im not using mods im just trying to install and keep multiple updates on my switch system itself via SD card or system storage.

Thanks for the clarification — I think I’m starting to get it now.

So just to confirm, the process is:

1. Install the update I want (like 3.0.3) using DBI.


2. Use DBI > Title Management > Installed Titles > MK8DX > Dump Installed Update and choose a folder (e.g., /switch/updates/mariokart/3.0.3/). DBI automatically splits the NSP so it fits on FAT32.


3. Repeat for the other versions I want to store.



Then whenever I want to switch versions, I:

1. Go back to DBI > Installed Titles > MK8DX > Uninstall Update to remove the current one.


2. Go to Browse SD > switch > updates > mariokart > [version] > and install from the .nsp.00 file — DBI reads the rest of the split files automatically.



If that’s the full method, then awesome — that’s exactly what I needed. Appreciate the help!

Let me know if I got any part of that wrong.

This is your answer but you have to use the tool to dump and install the various updates when you want to switch versions.
