Supported platforms

CERF is a 32-bit x86 Windows program (it runs fine on 64-bit Windows). The two executables in the archive do not have the same floor:

Program	Runs on
cerf.exe - the emulator	Windows XP and newer
launcher.exe - device picker / ROM downloader	Windows Vista and newer

On Windows XP there is no launcher: run cerf.exe directly from the command line, pointing it at a device folder you copied across from another machine.

XP / Vista support is best-effort

CERF is developed and tested against the latest Windows. Support for XP and Vista rests on the program never touching an API those systems lack - and that is easy to break by accident, with a single new call in unrelated work. A build can therefore stop starting on XP or Vista at any time, without anyone noticing until someone tries it. If that happens, open an issue - it is a bug, and a fixable one.

Development builds

Every commit is built automatically. The newest build is attached to the top entry of the build list - open it and download the artifact at the bottom of the page. It is the same program as the release, just ahead of it.

How to use?

Unpack the archive anywhere and run launcher.exe: pick a device, and it downloads the ROM bundle and boots it. CERF ships no ROMs of its own.
