Everything looks good except nothing runs...

[TroyBear12]

I have downloaded and installed Mame and pulled in a few games.  Everything shows up and acts like it is all good but when I attempt to run the games the screen just flashes up and goes away.  I found the debug log option and enabled that... all I get is a bunch of messages that appear to be checking controllers and such and then it increments the played counter for said game and then logs a few more messages.  I can probably grab some lines if that helps... I'm probably too old to be attempting to make this arcade but I'm just trying a small test at this point to make sure I understand what/how all this works.

Anything more I can check?

Have you tried just running your roms on the actual Mame emulator without running it through Launchbox?

As the prior post mentioned test the games directly in Mame (without using LB) to see if they run. If no, then that's your issue. Could be a rom issue, could be you have your roms somewhere Mame is not looking for them. Could be a few other things. It is always best to test directly in an emulator first. 

If they do run directly in Mame then it is likely a LB setting. 

>In LB go to >Tools >Manage >Emulators and edit Mame. Post 2 pics. 

          1: Details tab.

          2: Associated Platforms tab.

>In LB right click on a game and edit. Post 2 pics. 

          1: Emulation tab

          2: Launching tab.
