[RESOLVED] The automatic collection "Never Played" shows pdf from "Library" category and i can't remove them from there

Hello everyone!
I'm loving customizing this amazing piece of software that is Retrobat but lately i've encountered a problem:
i have added few of my old magazines to retrobat adding my pdf scans inside the "library" folder. This makes them show inside Retrobat in the collection named "Library" and that's exactly what i wanted to do. Now, the problem is, the collection "never played" also show all this pdf files as they were games i never played and doesn't matter how many times i open those pdf, they never gain a "played count" and so they never disappear from the "never played" list actually flooding it and making it not usable anymore.

I've tried opening them in every way possible, nothing. I've tried disabling pdf file format from "never played" but that collection actually doesn't allow you to disable specific file's format like other collections so i don't know what to do.

Any tips on how i could make all those pdf not appear in the "never played" collection?

Thanks for the help!

I found a solution and i'm posting here if someone encounter the same problem:

this happens because the automatic game collection "never played" uses gamelist.xml files inside systems's folders to determine if a game was ever played. Usually when you play a game the file gamelist.xml get automatically created and edited with your playcount, actually removing the game from the "never played" collection. This doesn't happen for the library collection because what's inside isn't actually a game.
To fix the problem i created a fake gamelist.xml with just the infos i need to remove those pdf from the "never played" collection.

Code:

</gameList>

As you can see, i just copied an existing gamelist.xml from another rom folder, edited what i needed and removed what i don't.
"Game id" is just random numbers i put it for the sake of its existence, i started with 99991 and adding 1 every new entry.
"path" is the path of the pdf i want to remove from the list
"playcount" need to be 1 or higher, that's what determine that the game was played before
"gametime" and "scrap name" i don't even think they are needed, i left them there because why not lmao

This way the problem is actually fixed and none of the pdf present inside the fake gamelist.xml appears in the "never played" collection. Yes, it's boring cause you need to edit it by hand and add your pdf one by one but it's the only way i found the fix the problem, if someone have better ideas to automate the process i'm all ears!
Hope this will help someone else
