Launchbox is not launching a Arcade ROM with MAME Arcade Full Set

[ABOhiccups]

I use MAME Arcade Full Set (0.276 Split). Everything was all setup by the wizard.

When I tried to launch a Arcade game. It does not launch into a ROM. I just open MAME and pushes spacebar.

The only option is to open up MAME and launch a ROM manually.

To better help you, can you please share some screenshots of how it's setup in LaunchBox? 

Edit your MAME emulator and show screenshots of 
- the Main Details section
- the Associated Platforms section

Edit one of your Arcade games and show screenshots of 
- the main Metadata section
- the Launching section
- the Emulation section

Thanks for the screenshots.  Are your MAME ROMs really located in the root of your D drive?  If so, that's fine. A little unusual. But fine.

Also in the same location, do you have the file namcoc71.zip?  (required along with timecris.zip for Time Crisis to run)

Yes and Yes.

It's not just Time Crisis. Same issue to other MAME ROMs. Instead of launching a ROM. It just pushing spacebar few times in MAME Menu.

When launching a MAME game from LaunchBox, I can't say I've ever heard of it only opening the MAME UI. Unless of course when you right-click a game and select Open MAME. Usually if there's an issue, you'd see a flicker of a black screen, then it goes right back to LaunchBox.

The only thing I can think of that may be the issue is the ROMs being in the root of the drive (vs in a folder), in conjunction with using the -rompath parameter to tell MAME where the ROMs are located.  Not that using the parameter is bad. It's it pointing to a root drive instead of a folder.

As a test, could you put a rom into a folder, change the games path in LaunchBox to this [test] location and try launching it?

I always use 1942 (1942.zip) because it's near the top and easy to find.    So maybe try something like D:\games\1942.zip and see if that launches correctly.

 

EDIT:  Just did some testing and appears MAME doesn't like (or doesn't know how) looking in a root drive for ROMs.  aka, you need to place the ROMs into a folder.

You can create the folder name of your choosing and move the ROMs there.  Then in LaunchBox, in the Arcade platform, select a game then press Ctrl+A to select all games.  Then go to Tools < File Management < Change ROMs Folder Path for Selected Games... and point to the new folder they're in.
