3DS Titles Disappeared From Home Menu

This page lists multiple examples of 3DS titles dissappearing from the 3DS Home Screen and provides recommended solutions.

Note: This issue does not affect anything installed as DSiWare, including TwilightMenu++ and games forwarded via nds-forwarder.

On the 3DS, Going to System Settings → Data Management → Nintendo 3DS → Software results in...

Titles with gray X's on them:

Install and run Faketik.

Titles appear listed normally, but still missing from Home Menu:

If this occurred after installing 300+ 3DS titles:

Delete some games from the Data Management screen until you’re under 300 titles.

If this occurred and you have less than 300 titles installed:

Install and run Chalenged's gm9 title fixer per their guide.

If you run into any issues with the above option, join the Nintendo Homebrew Discord and mention that you've tried to use the title fixer script.

Alternatively, you can manually generate a file that describes the contents of your SD, join the Nintendo Homebrew Discord, and send it in the #bot-cmds channel for further instructions. To generate the file, you will need a Windows/Linux/Mac computer, and a way to access your SD on said computer. If you wish to follow this route, choose your operating system below. (WIP)

Note: When the 3DS finds missing or corrupted data in the titles folder, it refuses to load the whole folder. the easy solution is to remove said missing or corrupted data. the hard part is finding the data. The gm9 script and the discord command do just that. The file the bot asks you to upload, 'title.txt', is a list of all the files and folders in the titles folder. this allows the bot to look for any folders that are missing files so you may delete them, which usually brings everything back. However, the title in question is presumably inaccessible and needs to be reinstalled.

"The microSD/SD card software management information is corrupted. Reset it now?" message:

If you have any games or saves you'd like to keep, follow this guide to Rebuild your Title Database. If you do not care about your current data, you can hit "Reset", which will render your current games and saves unplayable, and you can reinstall your apps afterwards.

"There is no available software data" message and/or installed custom theme is gone:

Your SD Card is not being read by your console. Ensure it is properly inserted into the console; if it is, backup the contents of your SD Card to a computer or phone, reformat the SD Card, then test its integrity.
