Hello everyone and thank you very much to all of you for all the work you do, especially the creators of Groobymame and the crtemudriver.
I have an Ati HD6870 and Ati Hd5770, which I have used doing all the steps to have a 15Hz signal on the TV, getting it.
The problem I have is that once the drivers are installed, even before taking the 15Hz signal, Groobymame does not work from version 0.27, and version 0.27 and earlier if they work, taking the original resolutions, but leaving some potions of video such as bilinear filtering, enforce aspect ratio, synchronized refresh and wait vertical sync.
If I edit these options and save them when I exit mame, they appear activated again in video d3d, the only thing I can change and it appears saved is the Video Mode.
if i uninstall crtemudrivers drivers , open all grooby mame and save the settings, I can play 15Hz with 640x480 resolution.
I have tried on 2 different computers and the same thing happened to me, I don't know if it is a bug in the drivers with those cards or what the problem will be, but I would appreciate any help because I am going crazy, thank you very much.
This is what I get when I run groobymame with the crtemudriver drivers installed, with cmd
