Sure. If you’d like some videogame samples as a start, you could go search for the Yea Videogame competitions on the site and download any of the sample packs from them. Those are solid. You could also go into the browser page on the site and search for s3xmodit format entries (or small formats like 24K, etc) by clicking the format icons on the left column, and checking out any of the results. Those ones would all include samples and would be openable by a tracker like OpenMPT.
Outside of botb, just a matter of searching around for what you’d like, and if you can’t find it, figuring out how to grab the samples yourself. It’s fun to have a nice personal sample store saved up on your computer
