Title: MAME not displaying correctly, MAME32 works fine?!?!
Post by: nintendoid on January 04, 2011, 02:53:09 pm

Hi

I need some help with my mame PC.

I ran mame32 on the system and its displays perfectly (as pictured below):

However when I run a frontend (mala/mamewah) it seems to mess the displayed image (shown below) all DK games look like this, vsSMB full screens but also does some crazy stuff with the image.

Originally I thought it was a display problem. Though when I screenshot the problem the screenshots show a perfect image.
So I thought it maybe a monitor problem, just tried a new monitor (lcd) same problem.

Anyone know of this problem? any suggestions if this is a graphics card problem or mame config? and how to fix it?

bad / broken graphic card drivers.... i know some intel integrated ones had issues like this.  try updating them.

the mame32 is probably just an older version which used a different way to output the video.

Or try switching to ddraw. Im guessing its a triangle because that's a d3d surface.

direct draw (vs direct3d).

D3D uses hardware acceleration to do the things like the bilinear filtering (for the smoothing of pixels). Hardware 3d acceleration almost exclusively relies on rendering textured triangles. As I understand it d3d output in mame is essentially texturing a single 2D surface composed of two triangles.
