Hacking Hardware Homebrew 3ds hombrew heavy loading time after putting in my new SD Card and System settings not loading at all,along with all my rom Games

SquiwarZey · Jul 22, 2026

Hello everyone,
This is my first post on GBAtemp, so if there is anything I could improve about my thread, please let me know.

I'm having an issue with my Old 3DS where Homebrew now takes over a minute to load, they used to load in about 3–5 seconds. In addition, System Settings and all of my DS Roms/Twilight Menu++ no longer load at all (unless they somehow take more than 20 minutes).

I might be wrong but, I don't think this is an SD card issue. I tested both my new 128 GB SD card and my old 8 GB SD card, and the problem is exactly the same on both. System Settings also fails to load even when I remove the SD card completely.

I'll try to provide as much information as possible, even if some of it ends up not being relevant. So

My new SanDisk 128 GB SD card arrived, so I formatted it from exFAT to FAT32 using a formatting tool. After that, I made a backup of my old SD card on my computer and copied all of the files to the new SD card.
When I inserted the new SD card into my 3DS, I immediately noticed that Homebrew took much longer to load, and System Settings, TWiLight Menu++, and my DS ROMs would no longer start.
At first I assumed I had made a mistake while Formattimg the new SD card. However, when I switched back to my original SD card, the exact same problem remained. I also tested booting without an SD card, and System Settings still would not load.

I found another thread on GBAtemp describing a very similar issue. Following the advice there, I previously used the NVRAM/CRC16 repair, which completely fixed the problem For the Thread Creator. However, when i tried the same,Homebrew became so slow that,the NVRAM tool can not finish loading, or maybe its something else but thats what I assume.

At this point I'm not sure whether the long loading times and the System Settings issue are related, but I'm out of ideas. Since its been very long with modding my 3ds
Thank you very much to anyone who takes the time to read this. I'm currently on my flight home, so I may not be able to reply immediately, but I'll respond as soon as I can.
Any help or suggestions would be greatly appreciated!
Best Wishes!

Does that mean you get a black screen, or what?

Usually when you reference another thread it is helpful to provide a link, or at least instructions on how other people can easily find what you are referring to.

Also, usually it's best to actually wait until your are in a position to reply before you make a thread like this.

What is the cluster size when you formatted it? Make sure its set to 32kb.

Use Guiformat when you reformat it.
