I think the "start" command might be the problem.

I can run MAME directly in a batch file all day and capture the output in a log file.

Also, I'm not sure but you might need to add: 2>&1
to the end of your command line to capture both standard out and standard error...


C:\Games\Emu\Arcade\Mame0.198b\mame64.exe -v -help > mameLog.txt 2>&1


EDIT: I found more about redirecting the output when using "start"...

Quote:



Escaping Redirection (not to be interpreted as "Avoiding Redirection")

Redirection always uses the main or first command's streams:

START command > logfile

will redirect START's Standard Output to logfile, not command's!
The result will be an empty logfile.

A workaround that may look a bit intimidating is grouping the command line and escaping the redirection:

START CMD.EXE /C ^(command ^> logfile^)

What this does is turn the part between parentheses into a "literal" (uninterpreted) string that is passed to the command interpreter of the newly started process, which then in turn does interpret it.
So the interpretation of the parenthesis and redirection is delayed, or deferred.
Note: Be careful when using workarounds like these, they may be broken in future (or even past) Windows versions.

A safer way to redirect STARTed commands' output would be to create and run a "wrapper" batch file that handles the redirection.
The batch file would look like this:

command > logfile

and the command line would be:

START batchfile
