So they say the OP made a "low quality post" for discussing how using vibecoding is dangerous for 3DS owners and we all aren't allowed to speak about it?

What's the deal with these mods lmao. This is a DISCUSSION forum on a DISCUSSION forum app. If we wan't to DISCUSS why AI slop is bad for the 3DS, why shouldn't we?

Ban me if you want, as someone actively learning real code in school it's beyond fair to call out the slop and warn others.

I was yesterday years old when I discovered CTGP7. Guys I own Mario Kart World, and I'll be brave, this is better.

I'm sharing this in case someone else runs into the same issue, because I almost thought I had lost all my installed games and homebrew apps.

What happened:

I have a modded Old Nintendo 3DS XL running Luma3DS.

I noticed two strange, empty icons on my HOME Menu that didn't launch anything and would crash when opened.

I went into System Settings → Data Management → Nintendo 3DS → Software and found two suspicious entries showing black icons and 0 blocks. I tried deleting the first one, but the system said it couldn't be deleted.

When I returned to the HOME Menu, ALL my installed games and homebrew apps had disappeared. Only the default system applications remained.

I went back into Data Management and noticed that the first corrupted entry was gone. I managed to delete the second one normally, but that didn't bring my games back.

The weird part was that all my games and homebrew apps were still listed normally in Data Management, with their icons and sizes. They just weren't showing up on the HOME Menu anymore.

How I diagnosed it:

After some troubleshooting, I found a tool called GM9 Title Fixer.

GitHub: https://github.com/chalenged/gm9-title-fixer

I ran version 1.1.8 and selected Quick Test. It detected exactly one broken title.

The log contained this error:

Failed checking in folder: could not opendir .../title/00040000/0d921e00 (5). It also suggested manually deleting the problematic folder.

What actually fixed it:

I connected my SD card to my Windows PC and navigated to:

Nintendo 3DS/<ID0>/<ID1>/title/00040000/

The entry named 0d921e00 was supposed to be a folder, but Windows was recognizing it as a regular file, approximately 2.8 MB in size. This explained why GM9 Title Fixer couldn't open it as a directory.

After backing up my SD card, I deleted ONLY that specific file (0d921e00), safely ejected the SD card, and put it back into my 3DS.

And that was it! ALL my games and homebrew applications immediately reappeared on the HOME Menu!

No reinstallations, no factory reset, and no need to rebuild my entire game library.

TL;DR:

If all your installed 3DS games suddenly disappear from the HOME Menu but still appear normally in Data Management:

1. Back up your entire SD card first.
2. Try running GM9 Title Fixer's Quick Test.
3. Check its log at SD:/gm9/out/title-fixer_log.txt.
4. If it reports a broken title, inspect the corresponding path on your PC.
5. In my case, a title directory (0d921e00) had somehow become a regular file.
6. Deleting that specific malformed file restored every missing HOME Menu icon.

Important: Don't blindly delete random files from your SD card. Make sure you identify the exact broken entry first, and always back up your data. A malformed directory entry may also indicate filesystem corruption or an SD card problem, so checking the SD card's health afterward is a good idea.

I don't know exactly what caused the directory to become a file, but I hope documenting this helps someone facing the same issue!
