Odd monitor anomaly: repeating display
« on: September 13, 2005, 11:45:17 pm »
Hi everyone, I have some weird stuff happening with my Orion monitor and Advancemame, and was wondering if anyone has seen something like this before.

The monitor is a Orion 20" 510lcb22, connected to a either a Flyback KFS-60314B or KFS-60344A chassis (http://www.jomac.net.au/images/Chassis/img73.gif). I am using the newest version of Advancemame for DOS with an S3 video card wired to the monitor with a custom built vga to arcade cable. The Hsync and Vsync on the cable are soldered together and the remaining wires are r,g,b and ground.

I installed advancemame, and went through a quick configuration, choosing standard 15khz monitor for all options. I then wrote a batch file that automatically starts advancemame, loading the game Tank Force (this game was originally in my cabinet, so I chose it since I figured it would give me the best comparison between mame and the original board).

Once I was sure that the game was booted, I plugged in my monitor and began adjusting the horizontal and vertical dials until I got a picture. My issue now, is that the picture on screen is actually a series of horizontally tiled pictures of the game. They aren't flickering or scrolling or doing anything weird, there are just 6 different identical game screens being displayed on the monitor.

If anyone can shed some light on this, that would be great. Is it possible that my monitor does not like hsync and vsync twisted together (the chassis only has one sync cable), or is it something different.

Please see the screen shots below




Thanks,

/bill

You don't have advancemame configured correctly.


It's not as simple as just answering the basic setup questions.

Get a copy of easy mamecab and try it.
(First see if you get a stable display in 15k setup mode)

Thanks for your quick reponse !!!!

I downloaded and installed Easy MameCab. I got my Arcade monitor working fine in the 15 khz dos setup mode. I then copied over my tankforce rom into the roms folder and launched it, and unfortunately, I got the same result as above.

I'm beginning to wonder if this is somehow the fault of my video card. The card is listed on the Advancemame website as compatible, but maybe it's having trouble creating modes for the standard resolution monitor (just a guess).

Wondering if swapping it for an ATI Rage II might make a difference. Please let me know what you think.

Thanks Again !!!!

Go ahead and try a different card.

Also read this thread for a current review of advmame card compatibility.
