Black screen when opening ROMs

[james-martin-engineer]

Hi all,

When I attempt to run a game using the MAME 0.256, I see a normal loading screen for a few milliseconds, then a dialog with black contents.

I've tried this with a simpler game like Double Dragon and a more complex game like Ultimate Mortal Kombat. Both have the same outcome. Both ROMs are tested using IVPlay with MAME 0.256

Eventually I get an error saying "timeout waiting for status update from MAME"

What am I doing wrong here?

I think there is a legit issue here.

For some reason the version of MAME that I build myself doesn't have this problem, but before I discounted this report I wanted to make sure that I didn't see the problem with the off the shelf binaries from www.mamedev.org, and I reproduced the problem.

I'll look into this - and thanks for the report!

I was able to trace this to something that happens to be present when I build MAME myself, but is not on the MAME 0.256 release binaries

Fixed with the BletchMAME 2.17 release
