How to change default video options for all roms?

[aldub516]

Hey guys, and first off, thank you as always. As I am nearing the end of my new machine, im trying to clean up a lot of the roms to make them as uniform as possible. I noticed as i play some games, they are all coming up different sizes. I know all games had different resolutions and proper proportions, but some games are booting into marquee mode, or artwork mode, while others boot full/max size. This is going to be for a friend who isnt toooo anal about original resolution, hed just rather not play a game where 85% of the screen is not being used. For example, joust boots up into "upright artwork US" which has the game very small and centered in the screen.. I have to manually set it to standard or even pixel aspect which does slightly stretch, but atleast utilizes more screen space. As i said i fully understand resolution, and even that vertical games will have room on the sides. My issue is mame is opening some roms with video options that just shrink everything down.

I talk a lot, so to shorten it, how to I make mame boot all roms in either standard or pixel aspect? Or other suggestions?

If I understand what you want correctly, you can do that by just opening the mame.ini in notepad. There should be some options something like VideoStretch 0, or ShowArtwork 1. Change the number on those. 1 = yes, 0 = no.

I believe is the "resolution" command in the mame.ini file.

It's currently set to (by default):  resolution                auto

Simply change it to:  resolution 800 x 600 (or whatever fixed resolution you desire).  If it's not there you can add it anywhere in the mame.ini file.  If you don't have a mame.ini file, you can create one clicking on run in windows and typing CMD in the box.  It will open up a command line.  Navigate to the mame directory and type mame -cc    This will create a default mame.ini file in the directory that mame is in.

Not sure if everyone knows this, but if you are using Windows Explorer you can navigate to a folder and Shift-Right-Click and select Open Command Window Here to get the command prompt to be at that folder location. Just an FYI incase it makes anything easier for the OP or anyone..

Good tip! I normally just open CMD from windows and type CD and paste in the directory via right click. This is even easier.
