MAME Full Romset Issues?

[SageOfSong]

Hi! 

I tried using LaunchBox's option to download the full mame romset for my arcade, and I noticed a lot of the games that were imported don't seem to work when I launch them. I get a loading screen for MAME, but then it closes out automatically without the game starting up.

 

Is there any way I can fix this?

Are you using the right emulator for your romset? With MAME, it's best to ensure your emulators and romsets match. I think right now they're on version 0.204.

Just because mame has the rom does not mean it is playable or working.  If you know the rom is from a working system then you may need a chd or bios file that you dont have.  Try running the game straight from the command line and mame will usually give you some info to go on.  Even if its a playable system lots of roms may have issues or be unplayable.  One of the fun things about mame.

Also to add to the two reply's already here, you do actually have a MAME romset right? because you said this,

Launchbox does not download roms, so if you were expecting that it did that will be why they do not work.
