I found a really old CD that has a bunch of game demos from 1998. It wasn’t too scratched up so I bought it for like $1 at a donation warehouse. I was originally hoping I could pass it through to a windows vm I already have working and use their compatibility options to run an old version of Windows that could play. I tried mounting it as read-only to see if the contents were safe but while running “sudo mount -o ro /dev/sr0 /media/rom” - I get an error “/media/rom: unknown filesystem type ‘iso9660’” Things I searched up on this suggested editing boot options and I wasn’t really expecting to mess with my system too much. Does Cachy have something in place for this kind of thing?
