Please forgive me for being a bit dumb but i am coming back to this tuff after a break of a few years!

I have recently installed QMC2 and have SDLMame running nicely, but unfortunately when i boot to the Arcade it starts up but i just get a black screen with no games of images etc. the startup is
21:10:56.263: arcade mode: launching QMC2 Arcade, command = '/Applications/qmc2/qmc2-arcade.app/Contents/MacOS/qmc2-arcade -theme ToxicWaste -console terminal -graphicssystem native -config_path /Users/karljeffery/Library/Application Support/qmc2'

I have tried a few different options but nothing seems to have made a difference, it used to work a couple of years back and i don't remember having to do anything to it to get it to do so so am a little flummoxed!

Again, please try to forgive the newbieness, but i have a lot of catching up to do and am just surprised i managed to get mame running again with the filters etc! I havent even tried to get stuff like Atari 2600 going yet, one step at a time!

Cheers for any advice, and thanks for a great bit of software!

I suppose you're missing some Qt module that the default theme requires. Does the "darkone" theme work for you? Otherwise use console-type "window" and post the log here.

Thanks for the quick reply - I have tried using the 'dark one' theme but there is no change, although thanks to your suggestion of outputting to a window I think I can now see where the problem lies, but solving it is another matter...

I have tried reinstalling the SDL2-2.0.4 framework in the Library folder with no effect.

You seem to be missing "QtMultimediaKit". I would have expected it to be part of the official package, but I can't check (no Mac). How did you install it? Official package?

Yes, official package for QMC2 and also SDL2-2.0.4 - very odd!

Well, actually not so odd (now that I remember that there are major problems building QtMultimedia 4.x on Mac OS X smile )... it's only required for the video snap support which you can - and have to - disable for QMC2 Arcade to work! With "-video off" QMC2 Arcade will use QML that doesn't import QtMultimediaKit.

and with that one option off it works! For some reason the preview image is too large but that is a job for later as i have just got in from work - thanks for all the help!

Can you provide me with a screen shot showing it?
