A few years ago, someone created a homebrew (NX Activity log) that allows you to display the time on the switch. This homebrew does not allow you to modify the game time stored on the console. I would like it to be possible to add an option that allows you to modify the time displayed on the user's real page and not just on the application

To explain my situation, I recently changed consoles and when I recovered my account, I created a new user on the console and link it instead of transferring it locally. This causes the play time on my user page to not update correctly. For example, my playing time displayed on Mario Kart is 100 hours. For it to be updated, I need to reach 105h on the new switch (205 hours total). And it's like that for all the games I have.

I ran several tests to understand how the Switch changes the play time on the user's page. On the console, there is the save “8000000000000080” which manages friends and the save “80000000000000F0” which manages the play log. However, each user of the console also has their own save of “F0” and “80” to display your own information. The user's "80" has the playing time of the last 20 games played and the "F0" has the total playing time of all video games by the user since forever. The playing time displayed in the user's "80" file is only updated when the playing time of the "F0" file is greater. So we would have to find a way to modify this file directly.

Since I don't have any skills in homebrew development for the switch, I was wondering if someone could add this functionality to this homebrew.

JKSV can open all of those already. My activity feed used to say I played ungodly amounts of hours of every game I owned when I found em. Enable the account system save option and writing to system saves options to do it.

I already have JKSV, but I haven't found how to modify the game time. The only thing I can do is backup/restore the system save where the game time is stored, but not modify it with the information I want. I also can't backup the save 80000000000000F0 because it doesn't appear in the list. I had to use TegraExplorer.

There's an extra step involved before it will show up, and you can just do what I did: Figure out the save format and edit it.

Yeah especially the flairs. It leads to think that you're actually releasing a homebrew, not that you're looking for one
