Hey guys. So I finally was able to get the crappy box resolution off of the video settings. I went thru Mame / tools / manage / emulators / edit / default command - line parameters / you have to erase no filter on the command line. I saved it and it looks so much better .But the new question is how to I put HLSL scan lines for it to stick on thru Launch box. This is a project . Please share insight. Im almost at the finish line.
