i thought i saw a tutorial of how to flip the monitor screen vertical and horizontal somewhere on the net..i cant seem to find it..anyone know where i can get it? or assist me on this? thanks
-
waht ya mean, lifting the Monitor and flipping it vertically ? or you mean the game oriented vertically (-ror, -rol etc) ?
-
oh..my cabinet has a horizontal monitor..but i got a game for vertical screen (Aero Fighter)..so i want to know how to flip the screen to vertical without using your hands to actual flip the whole monitor vertical..thanks

better call X-men or the A-Team unless you want to play it with your head turned sideways or have the whole cabinet on its side :P

what do you mean?

There is no way to play a real vertical jamma pcb on a horizontal monitor. You have to manually remove the monitor from the cab, and put it back in vertical.
-
then those tutorial about flipping the screen monitor were applied for what kind of game?
-
Are you talking about a yoke flip? That is for mirroring the image from left to right, or up to down, or both. It is not for turning a horizontal monitor into a vertical...a vertical cab has the same kind of monitor as a horizontal, it is just physically turned on its side.
-
ok, i see..so what cause the game to be flip upside down or mirror errror?
-
monitors were mounted differently in different cabinets and different mfg assumed different orientations.
Therefore some older games require the monitor to be rotated correctly.
GENERALLY, a horizontal game will work with any horizontal monitor that is mounted with the anode cap facing up.
However, a vertical game will typically vary depending if you rotate the monitor left (counter clockwise) so the anode cap faces left, or right (clockwise) where the anode cap faces right.
Newer vertical boards typically include a dip switch to draw the graphics rotated 180 degrees so you don't have to rotate the monitor.
The "quick fix" for a badly oriented monitor in vertical orientation is to flip both pairs of yoke wires.. red for blue and yellow for green. However this *can* lead to a slight change in color and convergence, so you should inspect the image with a pattern generator to ensure it is correct in the rotated mode.
No game can convert the output of a horizontal to vertical and vise-versa.... EXCEPT for the mame emulator itself (the real boards can't).
As to why you might have a mirrored image (only one set of yoke wires flipped, not both) is that some games actually have the monitor mounted face up, right behind the coin door, and use a mirror slanted in the back facing out. This allowed additional graphics or other effects taped on/around the monitor or projected onto the surface.
A common one like Kick(Man) comes to mind as that was used in their upright. Some newer (late 90's) games include some rifle/shooting ones. I think there was some black and white ones from the mid 70's that used them too.

My Space Invaders (when it's working) uses a mirrored monitor image. Gun games like T2 also used a mirrored monitor.
Back on topic, though. If you want to play your vertical game properly, you'll be needing to pull the monitor out and rotate it. Some cabinets do this more easily than others. What sort of machine is it? Do you know what it was originally?
-
the marquee is a Time Killers..and thats all on the machine..i dont think i can pull this thing out and rotate it..it only have screw hole on the left and right mount..and the lenght of the monitor is shorter than its width..
-
Yeah it sounds like you'd have to make your own mounts. It's really not hard. It can be done in less than an hour if you already have all the parts. I just don't know if you want to do it.
-
i just probably let it like that..i dont want to mess up the monitor or kill myself from trying to rip the monitor out..even though i know how to discharge it..i just scare to do it cause i never do it before.. :'(
