Title: Major Havoc + MAME = Problem
Post by: - r e n d e r - on September 06, 2008, 03:14:44 am

Hi all,

I'm trying to play Major Havoc on a cabinet I built which is using a 27" tv as a monitor but it is displaying much wider than the actual screen and scrolling the image from left to right when I try to move through the maze.  It essentially makes the game unplayable.  This seems to be the only ROM that produces this problem.  Has anyone else run into this or have a suggestion for a fix?

Have you tried Asteroid, Asterpod Deluxe, Tempest, Quantum or any other Vector games ?

I dunno how good you gonna get with a TV for a monitor for this games. The best Monitor for this games would be SVGA (PC monitors) capable of high resolutions.

I run asteriod on a 15khz arcade monitor and its not that great looking but I'll live with it.

Try forcing the game to run on 320x240 or 640x480, I dunno if TV can accept 640x480.

What do you mean scrolling from left to right. It's supposed to do that as move through the maze, as parts of the maze are off-screen. But, yeah, apparently 640x480i is terrible for these games.

What I mean is, it's as though the screen res is 640x480 and the game is 800x600.  So it's like the game is floating and when I try to scroll, the screen moves first until it gets to the edge and then my character moves.  I hadn't considered that it might just be a problem with vector games in general.  That's a bummer because I don't feel like going through the trouble of switching out the TV.  I guess I just need to buy an original Major Havoc now ;D

Have you tried using 800x600?

 Many video cards that can not go over a certain resolution,  change the way that the
picture is displayed.   They will scroll the larger image around just as you posted.

 Mame typically is set to auto select the best resolution for the game chosen.
However, on vector games it will usually choose the highest resolution possible.

 Try changing the settings from  "Auto"  to  a set resolution such as 640*480.
