Home Page Forums MAME MAME MAME 0.172 is out

It was compiled with DEBUG=1, what do I need to do to enable the symbols?

SYMBOLS=1

Ahh, stupid me, of course maybe I should fireup a highlevel debugger too, I've heard that Visual Studio would work?

Yes, for that I believe you just need to do "make vs2015", then load the generated solution file. Be warned, you'll need to tweak the number of concurrent project builds, as by default it will attempt to use all of your CPU cores, which can bog down the rest of your system.

Whoaa, thanks for the warning, I just got the bluescreen from adding SYMBOLS=1 I suspect, but I did a lot of other things too and it could have been a lingering problem from the crash. I will try again later.

No, it's far more likely that too many cores are being used. SYMBOLS=1 doesn't do anything in Visual Studio as far as I know anyway, it's controlled by the Debug/Release drop-down.

Ahh, dead end, I have VS2005, the free edition I guess, so the solution files can't be loaded ad I believe nothing else will work either. I try again with the SYMBOLS=1 adn see if am lucky.

VS2015 is also free (for the Community Edition, which matches the feature set of 2013 Pro), and MAME requires it.

I could trigger it when toggling between extend, mirroring and 'projector only' on my lap top with an LCD screen on the VGA output.

Now with symbols:

You mean Required as to work in VS? Or is mingw64 support dead?
