Fedora Linux 25 and 26 RPMs for x86_64 (amd64)

VICE 3.1 (packaged on July 1st 2017)

VICE is a Commodore Emulator that emulates Commodore 64, Commodore VIC 20, Commodore 16, Commodore 128 and others.

Use dnf -y install /your/path/to/vice-3.1-kk.x86_64.rpm to install this RPM and its dependencies. I try to provide the latest VICE release here (as RPM) for the latest stable Fedora Linux.

UPDATE 2017-11-07: I do not intend to provide the latest versions any more. Fedora Linux 26 standard RPM-repositories already provide VICE 3.x.
