Homebrew Custom .TGA only take effect in the Wii U and HOME menu.

I've been dealing with this problem for a long time, but I never bothered to look for a solution until now that I started using the quick start menu again.

The problem I have is this: I made a custom icon for Super Smash Bros, the new icon shows up on the Wii U menu, HOME menu and data manager.

Spoiler: Custom icon

But in other places of the OS, like the friend list, activity log, warawara plaza and quick start menu, it still shows the old icon:



Something I've noticed is that whenever I start an app or game for the first time, the icon and title being used at the moment seems to be permanently stored somewhere to used on those mentioned places until I factory reset the console (I assume it is some kind of cache). but I didn't try to mess with my NAND files because I don't want to risk bricking my current console.

So my question is, is there any way I can update the icons in these places too? Especially on the quick launch menu.

UPDATE: I got an answer from @GaryOderNichts on Discord. It is safe to delete the .dat file mentioned on my second post, after you do that the console creates a new file with a clean cache.



The only side effect is that all games will be hidden in the activity log until you start them individually.

I've been looking through the console files, and found this file: BaristaIconDataBase.dat

Here's the location where I found it:

/mlc/usr/save/00050010/10040100/user/common

Opened it in a hex editor just to make sure it was the file I was looking for, and indeed it has all the icons for every game installed on my console, as well as their title strings.

As it is in the saves directory I would assume that by removing it the OS would generate a new one the moment I access the Wii U Menu again, but I'm not experienced with this so I don't want to take the risk of being wrong.

So now my question is, is it safe to modify or even remove this file?
