In Reply to: Vertical games on Horizontal arcade monitor posted by Krusty on 21, 2000 at 3:01 AM:
You have to pay attention to the original res. of the game.... Some games are more 'vertical' than others. Galaga is one that is 'more vertical' than other. It is 224x288. Unfortunatly an arcade monitor cannot display 288 lines of resolution, so you get stuff cut at the top and the bottom. Other games dont use as may lines. Mr Do is 192x240. I think that is about all an arcade monitor can do(around 240). SO it fits. Others are just a tad longer and they will be playable or you can force them to run at a res that will MOSTY fit. 1943 is 224x256. You can force it to run at a slightly smaller rez and fit it on the screen. But tons of the older games like Galaga and Xevious and Dig Dug etc are 224x288. That seemed to be the standard. You will have problems with a lot of them. You may be able to get some of them close with fiddling with adjusting the settings of the monitor or forcing different resolutions.
The reason that the double thing does not work here is the in 640x480 mode, (which is not a TRUE 640x480.... it interlaced which is really tricking 240 lines to be 480 by alternating the signals) is that doubling the res is a number that is still more than the number of lines of resolution.
Options as I see it. (sorry not a lot of them)
1) USE a PC monitor. It can switch resolutions. A arcade monitor's res is fixed. (I didn't like this option cuz I think it looks like crap on a PC monitor.
2) Force a different rez in arcadeos that will be close and adjust the monitor size etc. to get as close as you can. Some will still probably cut off.
3) use 640 x 480. You will have to live with a small picture.
4) rotate the monitor.... a lot of work but everything fits great. (this is what I did)
That, in a nutshell is about all you can do. Maybe someone else knows something else to try, but I don't think there are any more options.
Good Luck
: I am doing some testing for my MAME cabinet project, and I have my video connected to an ATI Xpert 98 PCI card. When running horizontal games on my horizontal monitor, everything looks fine. However, when trying to run vertical games on the horizontal monitor, the top and bottom are getting cut off. I can run them rotated and they look great, except that I don't have a rotatable monitor. I have played with the resolutions, but none seem to let me see the whole screen, always cutting off the top and bottom, except for 640x480, which is WAY too small on the screen. For example, Pac-Man doesn't let me see the scores at the top or the number of men and fruit at the bottom. It is not a monitor vertical adjustment - it is being cut off by the emulator itself. The funny thing is, Mr. Do (and Mr Do's castle) display the entire screen, although they too are vertical games. This is throwing me off, since I would figure it would be an 'all or none' thing. The games I have tested so far that have cut off parts of the screen are: Pac-Man, Frogger, Donkey Kong, 1942, and Galaga. Mr Do is the only one that I have found that will let me see the whole thing, and I'm running that one at 320x240, like all the others.
: Does anyone know of a 'trick' to get this to display properly? I've seen where people say they've got vertical games to run on horizontal monitors just fine, so I don't know what they're doing...
: Thanks in advance for any help you can offer.
