Have you tried re-sizing the game screen? It could
be that somehow your 'game screen' has been re-sized and/or moved from the visible area of your TV, thus giving you a black screen but with sound... ie the game graphics are
playing, just on a part of the display that you can't see. This would also explain why you can see it on the preview screen when you pause the emulation.
If this has
happened, and you've played around with the configs, this config could have been set to 'use globally' thus over-writing all your previous settings and explaining why none of the games now work, when previously they all did...
Just a thought... Also, as Retroplay says, try WinUAEX v18 - it is an awesome Xbox update and may just fix this issue for you.
