Sets an advanced/miscellaneous option to use during operation. Returns the previous value. See definition of GM_MiscOpt_t32 type for a list of available options and their descriptions. The filename values take a const char*. For on/off options you can also use the special value GM_MiscOptVal_Toggle to toggle the value to the opposite of the current value.
