Subjectscreen aspect ratio arcade games? new Reply to this message

scroller and fighting games like
StreetFighter 2.
astynaxe, strider

etc..
what is the screen ratio of those games?.

actually want I want to do is have the best ratio for my Mame setup.

my HDTV 16:9 aspect ratio seems too wide when I stretch it all the way but when I enter 4:3 ratio on the setting the screen seems alittle shrunked for games like SF2.

anyknow what is the best compromise?

check on the resolution...
For example, SF2 is 384x224.
384/224 = 1.7142
4:3 = 4/3 aspect ratio = 1.3333
16:9 = 16/9 ratio = 1.7777

Therefore I would say that 16:9 is more appropriate if you can run at the original resolution. If not, try using 800x600 at 2x zoom with black borders on the top and lower halves of the screen (400x300 is closest to 384x224).

And so on... a bit of math can tell you what's the best to use depending on your available resolutions.

Except games where the monitor should be rotated; those are 3:4.

There's a few multimonitor games that use variations of those aspect ratios (12:3 in Darius, for example).

That's a common misconception (which I also believed in the past...)

Almost all arcade games are 4:3 or 3:4 (vertical) as RoushiMSX points, with the exception of multi-monitor games and a couple of games which have LCD displays attached. The pixel resolution is meaningless for aspect ratio. For example, Burguer Time has a resolution of 240x240, but it was shown in a standard 4:3 arcade monitor, and it was designed so. You can see that odd resolution games are designed always for 4:3 monitors just looking at round graphics in them. For example, the car tires in the beginning of Robocop are squashed if you think that the pixels were square, but projected on a 4:3 ratio the car tires are perfectly circular. This includes the CPS games, which have to be "crushed" a bit so they look properly.

All this senseless blurb should be rewritten properly and added to the FAQ, IMHO.

I remember seeing arcade machines of SF2 at different aspects ratio, so I suspected there was some amount of configurability with arcade monitors...

Good tip :-)

Agreed, no need to rewrite though.

Same goes for Neo Geo games, really. In some of the custom MAME builds people rolled, they'd "correct" the resolution of some of the games to discard the garbage on the side of the screen when in reality it was always there to begin with and arcade operators were expected to adjust it off the screen.

Since MAME takes pixel perfect screenshots it doesn't really help kill off the aspect ratio confusion (look at the CPS2 shots on MAWS, for example), which is another reason why I so strongly advocate using a program like FRAPS for snagging screenshots within emulators.

too long; didn't read version: My wife picked up Cooking Mama today for DS instead of picking up food to actually cook, so I'm eating a soy bean burger on a piece of white toast with a glass of pink lemonade for dinner.

Don't suggest that on the mame boards. I posted something similar to what you wrote above and was shot down by rbelmont and crew.

Someone probably just messed with the adjustment knobs on the monitor. I had seen a machine where the vertical was stretched to the point that you couldn't see the scores at the top.

actually it won't really be right. if you thinkg about computer monitor/lcd have square pixels if I remember older CRT and TV screens have rectangular pixels. so a 10x10 pixel box will be square on a monitor and a rectangle on a arcade screen.

I once owned a cab with 16:9 screen, came with neogeo MVS - never found out what games were supposed to run on that in 16:9 though

I don't know of any but I'd love to hear of some if they exist.

16:9 monitors are pretty rare in arcades, but they do exist. Almost certainly just a generic jamma cab that the operators just put a random pcb in, thinking that wide screen will attract more people.

Operators can adjust the monitor to get the display just right. Different boards may need slightly different adjustments however, so it's likely that the operator never changed the setting for any of the jamma boards they put in the cab. So exactly what aspect ratio you got was pretty much random.
