| Mortal Kombat doesn't sync - is it the ArcadeVGA or Arcade Monitor? |

Hi guys I've posting this up as I am hoping to get some help resolving an issue. I'm testing games on my setup, and Mortal Kombat did not syncronise... I got a rolling picture on the screen instead. Now, here's the problem: The webpage on the arcade monitor says it can sync to any vertical frequency between 48 and 65Hz. http://www.highway.net.au/parts/monitor_&_chassis/4808.html Mortal Kombat's 53Hz is well within that range. The arcadeVGA website says it has a special mode timed at 53Hz for Mortal Kombat. http://www.ultimarc.com/avgainf.html And yet, Mortal Kombat is NOT syncing. The question I'm putting out there for the community, is what test(s) should I do to determine if its the card driver or the monitor itself that is the culprit here. Any help would be appreciated. Cheers, Anubis. |

They didn't say any - they said "V-Frequency:48~65Hz" , which can really mean a lot of things. Mostlly it means that it is optimised for 50hz & 60hz modes. But ones in the middle, ie closer to 55 often are often out of range. That Mortal Kombat res on avga cards won't work for most of my arcade monitors, but works well on my Sony broadcast monitors. |

Most of the ArcadeVGA resoluations are 60Hz vertical, but some, which have a large number of lines such as 640 X 288 are 50Hz. So if the monitor syncs to these 50Hz and syncs to the 60Hz ones but not to the 53Hz thats very strange! Is only the one resolution affected? Andy |
| Anubis_au:
I've seen the monitor struggle (ie not work) with games that are designed for 25Hz displays. Pretty much every CGA-res game I've tried (1942, pacman, bombjack, SF2, wonderboy) all worked. I just rang the monitor vendor. They suggested that Mortal Kombat has a setting on the board to select between high, med and low res and maybe this is why I couldn't sync... sounds like BS to me but I thought I'd put the question out there... is there merit to their claim about a res switch? Some seting to flag in MAME? |

This may be a silly question, but have you tried adjusting the VHold pot? How badly is it rolling? Also I assume you are using the 401x256 AVGA resolution for MK? |
