Deleting Roms from XMB menu

Hi, I’d want to delete some roms from XMB menu, or changing the core to use them with, is this possible? Deleting the whole database can be an option, too, how to do it? Thanks in advantage.

That stuff is all stored in playlist files, though I forget the file extension for that. They’re just plaintext files, so you should be able to at least attempt to make some deletions/modifications there.

Open your Retroarch folder

Open the playlists folder inside

Open the .lpl file (with Notepad) corresponding to the system associated with the ROM

Delete the file path to the rom you want to remove

Thank you all for the answers. In Android, without root, you can’t access these files, I solved changing the Playlist path and rescan in folders. Thank you again!
