Hi again,
sorry for not answering for some time, but I didn't have the time to.
At first thanks for your input. Thanks to you, I read some more about the topic and the aspect ratio of actual arcade screens. So, yeah, I learned now that the native view is indeed not the correct way to display the screen. (Unless of course you want to analyze pixel by pixel.)
But in general, the suggestion with the LAY file, mentioned by DMala, is a good solution for my original question. This way, you don't need any MAME derivate and can use the original one. With LAY files, you can force the game screen into any size you want. So, even with Direct3D, you can get the pixel-exact look if you want to (with black borders on all four sides) or you can get a smaller image on a screen where MAME would stretch to the whole width or the whole height. You just need to set the right screen bounds and you can bring the screen into any size or form you want.
