You need to check out a tool called setdmd http://www.pinballbulbs.com/files/setdmd.html
Change your DMD to snow its so much better than orange
General options:
Anti Alias - Sort of sets the sharpness / blur of the DMD. Default is 50%. I like lower.
Border - puts a border on the DMD. No idea why you'd want it.
Title - puts a title on the DMD window. No idea why you'd want it.
Scanlines - puts CRT style scanlines on the DMD. Probalby also best off. DMD's were plasma and had no scanlines.
DMD Only - this is a default setting. Without it, the pinmame window pops up. Probably want this checked.
Intensity - The DMDs work on 3 levels of on and off for each pixel. This sets the intensity value for each. Sorry, but my preview cannot handle changing these values. You would have to change them and run a game.
Rotation - For cabinets you probably want none. This is the window rotation. Note that this is a registry setting but many table scripts have this hard coded. You would have to also edit those tables and search for the ror or rol = 1 settings and remove them for this tool to have impact on those tables.
X pos, Y pos, Width, Height - This is the DMD window location and size.
Change color - If you check this, all the tables will be updated to the color you have selected. This is useful if you want all your tables to be a standard color. For some reason many tables are often in different color DMDs. While these looked neat, they were not authentic, so hence this switch. The checkbox is present so that if you do not want your DMD colors changed you can uncheck this and it will not be impacted.
Set Default - This will load the default PinMAME color.
Click to change - you can set the color you want, can be any RGB (red, green, blue) value.
Some of the other buttons at the bottom::
Load MAME Defaults - Loads into the form from what I can tell were the defaults pinMAME uses.
Load First MAME ROM Values - If you have already configured your tables, or you just want to first manually configure one table and then use this tool to apply to the rest, then this button is for you. You can click this and it will load the first configured MAME ROM value from the registry into the form. The ROMs are stored in the registry in alphabetical order. You can open the registry if you want and find the first ROM or maybe look in the ROMs directory on your disk.
Save As Default - Should save the current values in the form as a default that is loaded next time you load the app.
Install ROMS and Update - This will scan for ROM files in your ROM path that you specify (in the next box that pops up) and will add a registry entry for each of these. It will set the default values you have in the form to each of these added ROMs. It will also mark each game as "Played" so you do not get that super annoying box asking if you legally have the right to run the ROM. I assume that if you load this tool, you have that legal right to run the ROM. This will not update all other ROMs with current settings. Only new ones that it scans and finds.
Update All Installed ROMs - You should use this each time you want to make a change across all your ROMs. This is sort of the "save all" button.
