synacor-emu

This is an Synacor challenge emulator. It is complete.

Building

make (gmake on BSD) will build the emulator, synacor-emu.

Simple Emulation

Invoke synacor-emu <romfile>.

Tracing

Use the -t=TRACE_FILE option to synacor-emu to log a binary trace of all instructions executed to TRACE_FILE. Use the -x flag to dump in hex format instead of binary.

Save and Restore

Send a USR1 signal to the emulator to save the current machine state to "synacor.save." Restore a saved machine state with the -r flag, like: synacor-emu -r foo.save.

Hacking
