Running CERF from the command line

The launcher is the normal way to start CERF: it downloads the ROM bundle and boots it. Everything below is for running cerf.exe directly.

Commands

Command	Action
cerf.exe	Boot the default device
cerf.exe --device=devemu_ce6	Boot a specific device
cerf.exe --guest-additions	Boot with Guest Additions
cerf.exe --log=ALL	Enable every log channel
cerf.exe --flush-outputs	Force-flush logs - avoids truncation on a crash, but is very slow

cerf.exe --help prints the full command line, including the list of board ids.

Logs

CERF writes cerf.log next to the executable. It is quiet by default: only critical lines are written. Turn channels on with --log=ALL, or name the ones you want:

cerf.exe --log=BOOT,JIT,MMU

If CERF dies, it also writes cerf.crash.log next to the executable - every other thread's register state and a snapshot of its stack at the moment of the crash. Both files are what a bug report needs.
