Eh nothing interesting. The water would be in the bucket but pool and bead much quicker, instead of spreading and getting the bucket ‘wet’. Kind of like a hydrophobic windshield coating.

Anecdotal, but when I was just messing with qBittorrent and its search feature, I found some ROM sets just by searching for system and sorting by size. This torrent for example is not necessarily comprehensive but contains a lot of roms of which can be shared with friends and family :)
