GM 2nd monitor marquee issue

[jitu]

Hi again,

I now have a cab up and running powered by pc running GM with Bigbox frontend. Everything looks beautiful! Since, bigbox can output marquee to a 2nd monitor, I added an lcd to test this feature and it works great except when I launch a game, the marquee shifts up. Any idea what could be causing this and if there's is a fix?

This is how the marquee looks on the 2nd monitor. Looks normal.
Main monitor displaying the games:

...and this is what the marquee looks like once a game is launched:

Running an emulator on fullscreen exclusive mode will affect whatever is placed by another app on a different monitor. The only way to get this working is to use MAME itself to display the marquee on the second monitor.

Ahh I see. Appreciate the feedback!

Calamity, I tried outputting marquee using GM, following the suggestions from another post from 2018, and doing so output the game in both displays.

Arcade crt being the main display and lcd being the secondary extended display. for screen0 I have \\.\DISPLAY1 (for crt) and screen1 I have \\.\DISPLAY2 (lcd)

I verified those displays are correct using arcade osd.

You have to use the view options in mame.ini, one has to be set for the marquee view. I can't remember the details.

Hi Calamity,

I have set my mame.ini like this and it now somewhat working. No longer getting dupe output.  However, the similar shifting is happening with the lcd where the marquee is suppose to be displaying.

I think I have it figured out! Just took some tinkering and bunch of trial and error lol!

Not sure if I should ask this next question on here or over at BigBox forum...I will start here just in case tho. So, I have GM outputting marquee to lcd, but now BB wont respond to keyboard or joysticks when a game is launched. Started doing this after configuring mame.ini to handle marquee.

Problem resolved after restarting PC.

Guess I spoke too soon. The issue persists. What's happening is when BB launches a game, GM also opens as a separate window due to marquee now being enabled. This causes the focus to change from BB to GM running in the background, therefore no joystick or keyboard inputs are being registered in BB.

Anyone know if I can use some kind of script to let BB to stay in focus when launching games?

The whole point of showing marquees through MAME is not using the frontend for that. GM will not work properly with a background app using the screen at the same time.

Oh ok well let's scratch that idea lol!

Went back to using the marquee feature from BigBox instead. Since the marquee shifts once the game starts, I just wanted to see if it would make a difference if I used 2 lcd screens. So, I unhooked vga cable coming in from the crt and hooked up a another lcd in it's place, loaded up BB and fired up a game and the marquee is displayed properly.

My simpleton brain trying to understand why it doesn't work when a crt is plugged in even though crtemudriver is sending 15khz out the vga port.

I don't know what kind of game this pc playing with me but marquee works fine now with crt plugged in. Must have done something to registry or wherever after hooking up the second lcd. I don't know anymore lol!
