-EmuHawk takes some command-line options which aren't well-documented; you might be able to figure them out from [the source](https://github.com/TASEmulators/BizHawk/blob/78daf4913d4c8e47d24fc14d84ca33ddef913ed4/src/BizHawk.Client.Common/ArgParser.cs).

 On Linux, you can pass arguments to `EmuHawkMono.sh` as expected and they will be forwarded to `mono`. (You can also `export` env. vars.) All the arguments work as on Windows, with some caveats:
 * file paths must be absolute (or relative to the install dir, `EmuHawkMono.sh` changes the CWD to there);
 * `--mono-no-redirect`: if you pass this flag *as the first argument*, it will be eaten by the script itself, and stdout/stderr will *not* be redirected to a file. (It's redirected by default.)
