I'm talking about the web database, see the link. It sound like you might be talking about the desktop client. I just uploaded an image using the web UI and select Box - Front. There is no game file.

I figured it out, but it's not perfect: 1. I converted the merged set to a split set. 2. I set up HBMAME as an emulator and used this emulator for importing the hbmame split set 3. I googled and downloaded an unofficial hbmame core. Now many of the games I try to launch work (the "rom not found" message does not poop up anymore). However, not all of them work. The problem I believe is that the hbmame core represents the version 220 while the romset (and teh HBMAME emulator) is version 245. I think that might be a reason that not all of the games work.

I've been having a lot of crashes as well and it seems to happen when I right click on a game to bring up the context menu or expand the left systems arrows although it doesn't happen every time. The program will close without any message about a crash and will restore immediately upon launching.

In LaunchBox, edit your MAME emulator and uncheck Extract ROM in both the main Details section the Associated Platforms section If there's still issues, share a screenshot of both those sections so we can have a better look.

Depends on the platform. MAME (and a couple others) aside, ROMs are typically named after the games Title. For MAME (Arcade), LaunchBox will parse the xml result from mame.exe -listsml to "convert" the ROM name to the games' Title. I didn't realize Daphne had its own set of ROMs. I've only ever used Hypseus Singe for LD games, which uses MAME ROMs (and can be scraped as Arcade). You can watch a tutorial here. Provided Daphne has an accessible means of "translating" ROM name to game Titles (e.g. the -listxml parameter or a definitive source), you might want to put in a feature request (top of this page under Help & Support) to add it as a Scrape-As value.

@Jabb3rJaw Yeah, I know exactly what you mean and welcome to the real world of LaunchBox themes. It’s not that you did anything wrong; it’s simply that the ecosystem was never designed to be plug-and-play like Hyperspin. Here, if a filename doesn’t match the LaunchBox database perfectly… the theme just won’t show up. And yes, a lot of creators upload their videos “as is,” without following the official naming conventions, which breaks the automatic sync. @CTRL-ALT-DEFEAT does amazing work ; seriously but like many veterans, he posts his themes raw, without always renaming them for automatic compatibility. So you end up sorting and renaming everything yourself. And yeah, it takes time… but it’s not your fault. That’s simply how Big Box works. The real difference in LaunchBox is naming discipline. As soon as you use No-Intro names, everything lines up. No surprises, no invisible themes, no missing videos. No-Intro is basically the backbone of the whole system. And then there’s @Suhrvivor really clever guy who organized everything into predefined folders. Check out his post: he set up a structure so clean that it’s basically plug-and-play. You download, drop everything at the root… and bam, it just works. Honestly, this kind of standard should be enforced by the staff. Not to restrict creators, but to make everyone’s life easier. When the base is clean and filenames follow a universal logic, the entire user experience changes. And despite the little headaches here and there, what you wrote is really motivating. Knowing that a single theme makes you want to turn your PC back on — that’s exactly why we keep creating. For that little spark. That moment when you dive back into your collection just because the vibe pulls you in. In the end, you’ll see… you’ll spend more time looking than actually playing. And that’s where the magic really happen

i also have this problem in attract mode. after a few hours BB just closes and i'm left with the desk top. Does it with beta 13.25 also.

I have upgraded the MAME romset to 0.283 if I run MAME from its folder, it loads correctly and plays the selected rom. when I start MAME from the context menu and the select the rom within MAME, the roms load correctly Every attempt to start via Play in LB fails.

HBMAME Roms =/= MAME Roms MAME cores in RetroArch are looking for MAME Roms, not HBMAME roms. They're not compatible. And why are you using RetroArch for MAME / HBMAME?

The real question is, what did you do with the image? Where did you save the image and what did you name it? Is it a PNG? The image must have the exact same name as the game file --> ending with -01.

I have uploaded box image art for Dark Chamber - Limited Edition, however it does not seem to use it as the default box image to display. I get the grey box "Box Image Not Available" on listing pages. What have I done wrong?

I was able to import a merged HBMAME romset and they launch fine with the HBMAME standalone emulator. However, I would like to use retroarch and here I encounter some problems. When using Retroarch and manually navigating to the rokm file and launching it, it works with the regular mame core. However, when trying to launch the imported roms from LaunchBbox with retroarch selected as the emulator, I sometimes get an error message saying: "The ROM file you've specified does not exist." I guess that might be an issue because I have a merged set and not a split set, whereas the additional apps for the rms are listed as separate ...zip files. However, I can importa standard mame roms from a merged set just fine. So do I absolutely need a split HBMAME set? Why won't a merged set work even though it does work on regular mame?

I updated to beta 13.25. Initial testing shows randomness is better. It will scroll through games starting with letter A for and handful of games then move to B for a handful of games, then C. Didn't seem totally random. Though at times it would deviate from this pattern and just pick games with a totally different starting letter. I hope you can under stand what i'm trying to say. One thing that is happening is after a few hours of scrolling though games, LB will just close completely and leave you at the desktop. Not sure why. previous versions id have LB just crash and stay frozen on a screen having to reboot to get it back up and running. I just realized this occurrence and behaviour is happening in attract mode. Not screen saver. I will test further in screen saver mode. Sorry for any confusion.

Does anyone have a recommended controller mapping for LaunchBox? I’m looking at the X-Arcade mapping (see below) as an option, but changing Player 1 up/down/left/right to arrow keys and adding “Enter” somewhere as one of the keys.

Is it a MAME ROM? When I looked, "lair" doesn't exist. But "dlair" does. (Maybe 'lair' is an old ROM name???) It’s not a MAME rom. I’m trying to do this with Daphne roms for now, with the ability to do it with any roms in the future. How does LaunchBox know whether or not the rom name is part of the set? (I’m looking for a way to fool LaunchBox into thinking that it’s a valid rom name so it will import it under Arcade. As-is, I have to import all of the Daphne games as MS-DOS games.)

I also encountered this issue and came here while searching for a solution. I'm experiencing the exact same symptoms. When I use Launchbox to run RetroArch with the FBneo core, it exhibits the same symptoms as in the video. The screen repeatedly flickers, showing and disappearing text strings.
