I come back with another issue now. I chose the games and exported them using the LaunchBox settings. I removed the arcade set from LaunchBox and started importing the games I exported earlier, but they don't start. There's a 1-second black screen, and that's it. What do I have to do? And I also want categories like beat-ups, fighting, vertical fly, etc. I suppose I imported them correctly. I tried to import them via ROMs in LaunchBox, and I selected the ROMs folder.

Finally managed to fix everything by adding them manually via launchbox; most were already in the full set, others were just downloaded one by one from the internet. Now all good and working. Thank you for the help.

I managed to download MAME 0.284 (non-merged), imported the set into LaunchBox, and was looking for the game Gunforce2. Nothing. So I downloaded the game, and I imported it manually from LaunchBox—still nothing. Like before, the game is not imported at all.

The question is how to delete the games from the complete set so I can reduce its size to 4GB. As I said, I need, of course, to see the game picture or gameplay so I am sure of what I delete. I want to delete directly from LaunchBox. Will it be entirely deleted from the name set folder? Please elaborate on the steps. Thank you!

And how do I properly curate the games from the non-merged set? I mean, I want to make it the same 4GB only games that I want, but to delete the games that I don't need, I need to see the games from the set like pictures or videos, so I can choose properly. Can you guide me, please? And you say that it is better to remain on the non-merged version? Can I add new games, or do I always have to create a new set?

So I need only ROMs for 0.253? I worked a lot on this set to make it only 4 GB of the games that I like. Now have to do a new one again? Also, my set is merged. Is it better to have merged or non-merged sets? And how do I do if some games are not available from the beginning in the sets, like some hidden gems, for example?

My MAME set is 0.253. I have everything well organized in folders, games, and emulators. Regarding that plugin, what should I do with it? I have never used it before. This is what i receive from the plugin gunforc2.zip.txt

I am using Launchbox 13.24. I managed to add the game with CTRL+N, but it is not starting, just a 1 sec black screen and that's it.

I tried via Tools - Import - Roms - Single Platform, I chose the rom file, then I selected platform Arcade, then emulator MAME 0.253, then chose copy file to my launchbox games folder, then next, next, and when arrive at ready to import window there is no game, 0 games, bassicaly is not see it at all to import. CTRL-N does not even find the game, only the first Gunforce and another Gunforce for SNES, no Gunforce 2.

I Im trying to add some single ROMs for Arcade, but none of the games show up, so they can't be added. I downloaded the ROM game Gunforce II, but it doesn't add. What do I have to do? The ROM I downloaded from here xxxx Im just looking for some hidden gems that I don't have. The platform I have is MAME 0.253, if that matters. PLEASE HELP!!!

At the end, I chose a different one; it seems to be working well, but I will also try your way. Thank You! I would like to know if there is a similar menu system like MAME's on other platforms, such as NES, SNES, Xbox, and Xbox 360. PS123, etc

I tried, but it doesn't let me choose the guide button; all other buttons work, so I have to select any other button, unfortunately

Good to know, but I see it's only possible on the keyboard. I want to assign the menu key to a specific button on the controller, but pressing that button does nothing. Is there a way to select a button on the controller instead of the keyboard?

Does anyone know how to open the service menu in MAME on LB using an Xbox controller? I want to add a specific button on the controller that opens the menu. How do I do that?

Man, you are unique; you make my day. Thank you. Now it's working. Many users told me I must have a new set of MAME ROMs. I work a lot for this set of only 4 GB. I import the ROMs from Android transfer via LB on Windows, which is very easy. One thing I want to know is how I enable the screen to appear in MAME settings, like on Windows, via the TAB key. Where I can choose cheats and other stuff, I don't want to do it via RA; I prefer old school via MAME directly. Is it possible? Also, I prefer the Xbox series Bluetooth controller 🎮 Is there a way to configure one time for all systems? Or do I need to do it for each? Update: I tried more arcade games from different systems, and I noticed that not all are working, for example Capcom system III not working at all, other systems working, but has glitches in the graphics. Can you tell me please what other settings should I change?
