Home Page Forums MAME MAME mess/ume 147 -> 149 vectrex bug

Hello everyone,

I think I found a bug in the vectrex emulation with mess / ume.
And this bug is present since at least version 147 (the oldest version I tested).

The bug occurs when I play with minestorm 2.
I made a video of these bugs: http://www.jammaplay.com/en/video-4KXRJP

As you can see, at 2m35, 5m23 and 6m22, the game freezes, the screen goes black and sound bugs occur.
And if I make no input during this time, the game continues normally.

But this is very frustrating: on the original hardware these bugs do not exist.

I do not know what may be causing the problem, but I am ready to help by doing all the tests that you ask me to do.

For information, I'm on linux and I compile myself my own version of EMU.

And from what I'm reading on the source code, Mathis Rosenhauer wrote the vectrex driver, but I can not find his email address.
Do you know where I can contact him ? Or does he visit this forum? Or someone knows him ?

Thank you very much.

I think there might be some 6809 bugs still lurking. There are reports of some crashes / hangs with Qix, and now this..

to be expected when a CPU gets redone completely, try to find a version before the CPU core was rewritten (can't remember the version #)

0.147 is from September of 2012; the cycle-exact 6809 landed mid-March of 2013.

ah, yeah, can't be that then, I forgot our version number increased so slowly these days ;-)

I remember it flashes and that sound playing. I thought it the way it meant to be. I never own any of these games. Anyway thanks for reporting this issue.
