1st, your game is in your "MAME" platform.  Missing the Edit Game - Emulation screenshot, but I assume it's pointing to your "MAME" emulator.

Next, your "MAME" emulator has the Associated Platform "Arcade" assigned, but not the "MAME" platform (which is the platform that the game is in).

But don't think those have anything to do with your issue as the game actually does start (for a few seconds).  But do check that the game (under Emulation) is pointing to your "MAME" emulator.  

In the video, did you press any keys right before it closed MAME and jumped back to LB?  One odd thing is that when it does jump back to LB, it goes back to the top of your "All Games" list.?.?.  (Instead of back to 1942.)

 

In Edit Emulator ("MAME" emulator), is there anything inside Running Script?  If so, what?

1. It's pointing to Mame.

2.  I will change it but it has worked in Ver 12.7.

In the Video, I did not touch a thing, all games load and just seem to time out after about 5 or 10 seconds.  If i quickly load it and insert coin and start, it will actually play the game for a few seconds before it closes.  And I confirmed this with about 30 random games in my library.  All games i tried do play perfectly outside of LB & BB.  I'm a little lost on what to try next.. both my arcade machines have been working for the last 4 years or so starting with ver 9.7 and did not have any issues up till now.  Thank you for looking into this with me.

and i was bored,... well no its driving me crazy that i cant figure this out so i have tried 3 older versions of LB fresh installs on 3 different PC's and 3 different versions of Mame, re downloaded just packman rom for quick testing and none of them will work at all. All do the same thing. All run pacman just fine through mame standalone.  PC's all running windows10.  That testing being done, do you think a windows update may be an issue since there was on last week? idk running out of ideas.

I don't think so.  That fact that, via LaunchBox, the games DO load indicates MAME and your ROMs are fine.  If there was an issue with either of those 2, you wouldn't even see the game. Couple that with the fact that when you run them directly in MAME itself and they run fine.

The issue is that when you launch a MAME game from LB, after it IS loaded, something is telling MAME to close after a few seconds.  Watching the video, it's 'coincidentally' about 10 seconds after you launch the game.  Also note that when it does exit, your selected game jumps to the 1st game in your view.

Experiment #1:  Click (don't launch) on a game lower down on the list.  Say... "1942".  The right sidebar will populate with 1942's details.  Now press the Space bar.  (see "Also note.... jumps to the 1st game..." above).  [this is more of a rhetorical experiment]

Experiment #2:  Edit your MAME emulator.  Go to the Running script section.  Comment out the last 3 lines using a ; (semi-colon) at the beginning of the line(s).  Just like the 1st line is.  Click OK to save and close.  Launch a game.  Is it still exiting the game approximately 10 seconds after being launched? 

[conditional] Experiment #3:  If the game is now NOT exiting itself, does anything happen if you press the Space bar while in-game?

OMG! Thanks, I think that did it.  Experiment#2 it worked on my work PC (test PC) lol.  I let it run for about 20mins or so played a quick game and no crash.  I will attempt on my arcade cabs and let you know. I should have time this afternoon.  Keeping my fingers crossed.

You're welcome!  But to be fair it was @launchretrogirl2562's idea to delete the script (brute force method of commenting out the lines. lol).  

But since that worked, this leads me to believe that when pressing the Space bar while in-game (Experiment #3), it will close MAME.  (Which ain't good. ;))  Especially if Button-3 on your cabs are mapped to Space.  If that's the case, SOMEWHERE you have the Space bar mapped to Exit MAME.  Most likely in MAME itself.
