25" CRT TV Nvidia 6800 Svideo Resolution Help
« on: November 26, 2010, 08:01:45 pm »
Hi I wasn't sure where to post this but here is my dilemma.
I'm using a 25" CRT TV for an arcade cabinet that I have built. I have a 6800 AGP video card with the latest drivers installed. The resolutions I can choose from are 800x600 and 1024x768. This is great until I decided to play a game called Super mario war. The game runs in windowed mode but as soon as I put it in fullscreen mode my screen goes black. I posted on there forum as well and they mentioned that the game runs in 640x480 resolution. I'm wondering since this is not an option for me on my desktop properties that is why I'm getting a black screen? Is there a particular driver version that will allow me to have all three resolution options and the game will work? I have the tv connected via Svideo cable. Any help would be appreciated? If there is no driver is there a graphics scaling program that will scale the window mode to be 800x600?

The reason I ask about a scaling program is I have some of the Touhou games and when I try and run them at full screen my screen turns black.  I found a program called vpatch (vsync) for them and it contains an .ini file I change the resolution to 800x600 in the file and the game runs magically in fullscreen mode.



Thanks

Are you using a front end? The reason I ask is because I'm using MaLa and that allows you to specify a custom resolution up front.
I'm running a 27" TV in my vert cab and force everything to 640x420. This fits all the games perfectly on the screen and the TV has no problem with that resolution.

I'm using Hyperspin as my frontend.  I have my desktop running at 800x600.  If I right click on my desktop and choose properties the only resolutions I can pick from are 800x600 or 1024x768.

Sorry, I'm not familiar with Hyperspin. MaLa lets you put in whatever custom resolution you want.
I also don't know if you're talking about setting your resolution in Windows or Hyperspin. If its in Windows, when you right click and get to properties, is there an Advanced tab? There should be a setting under Advanced to List All Modes.

Yes I do have an advanced tab and I then click list all modes.  If I select 640x480 with 32, 16 or just 256 colors my screen turns black.  If I choose 640x480 with 4 colors It works but the screen looks like crap and it still doesnt play the games it then gives me a video error.  Maybe my TV just doenst support 640x480?
