@uhhhhhhhhhhhhhhhhhwyanwunt I'm thinking out loud some ideas. Try the following;
- In your current version, instead of selecting the add game button, just go to the folder where the games are in Windows explorer, and drag and drop them into Launchbox. Import them like that, and then close Launchbox and reopen it, see if they are there.
- You could try maybe backing up your current PS2 xml in the Data folder, and use one of the older backup files from it (in case the xml got corrputed somehow and is not letting you write in it.
- Try what @Headrush69 said; in a completely different folder, install the previous version it worked for you (9.8 was it?), and import those PS2 games, close the app, relaunch it and see if they are there.
- Last option, install a clean current version of Launchbox (the one you are having problems with) in a different folder, and then try importing those two games in it. See what happens after relaunching the app.
Hope you can resolve this as Launchbox is a great app for managing games.
