Well, this is awkward. I've installed VICE on Gentoo (Commodore 64 emulator), and... can't start it. I've looked into distfiles and I should have "x64" as a starting command (also a bunch of others programs) but there is no such thing.
Here are the USE flags, which I have:
app-emulation/vice-2.4.22 alsa gtk ipv6 lame nls png sdlsound threads vte zlib
Any advice ?
