You need to download "rogue64_v1.03.zip", which contains a rogue64.crt file. This you can drag&drop into Vice. Let me know how that goes 😊
Thank you for your quick reply. After a bit of search I finally found the files. Lol. My bad. But it is a bit like a roguelike to find them ;-) Thank you. It is a really great game. It is so nice see devs care about these systems.
