Your Friendly A.I Overlord

Make sure that in LaunchBox > Tools > Manage > Emulators > RetroArch, the checkbox "Extract ROM archives before running" is unticked.

Not to mention, do your games run in RetroArch directly? If they don't, there's no point in troubleshooting LaunchBox yet.

This is necessary because LaunchBox pulls metadata from mame.exe. Metadata RetroArch doesn't have. I do not use RetroArch for Mame emulation, so I can't help you much. But this is important: - The games must run in RetroArch first. - Make sure that in LaunchBox > Tools > Manage > Emulators > RetroArch, "Extract ROM archives before running" is unticked and that in the "Associated Platforms" tab, everything is set up properly. - All games must be set to use RetroArch as the emulator. You need to tell Mame standalone the location of your roms. Either via the Mame gui > Configure Options > Configure Directories > Roms, or by editing mame.ini. Yes, this is a hard requirement.

That is not enough. During import you told LaunchBox to use Mame standalone for your games. You have to select all your games (ctrl + a) and bulk edit the emulator to RetroArch. Make sure that in LaunchBox > Tools > Manage > Emulators > RetroArch, "Extract ROM archives before launching" is unticked. But do your games run when launched in RetroArch directly?

Have you selected all your games to use RetroArch rather than Mame standalone?

👍Great! Leave all your sorrows in 2021. Have a nice new-year!

I'm on the latest version of LaunchBox (12.6) and for me video snaps show up in the Emumovies tab. Let me stress you need a paid Emumovies membership. A free account won't suffice.

The LaunchBoxDB does not offer video snaps. For Emumovies they're only available with a paid membership.If you have a paid membership for Emumovies, make sure you have entered your credentials in LaunchBox > Tools > Options > Integrations > Emumovies.

Put the command-line argument in the Epic Games Launcher itself. This requires you to launch your game via the Epic Games Launcher url. (Like when you have imported your games from the Epic Games importer into LaunchBox or use the shortcut created by the Epic Games Launcher.) Open the Epic Games Launcher > Left click your gamer tag (in the upper right corner) > Settings > Scroll down to "Shadow of the Tomb Raider" > Expand > Tick "Additional Command-line Arguments" > Enter -nolauncher in the field below. See my screenshot as an example for Borderlands 2. *Edit* To clarify, if done this way, you don't need to add command-line arguments to LaunchBox. Also: Now I understand your question. Shadow of the Tomb Raider is free on the Epic Games Store. 😁 (All three Tomb Raider games are.)

No problem. Glad you got everything sorted out. Like you said, there are many bad or old bios dumps out there. And if the documentation lists the MD5 checksum, it makes it a lot easier to find the correct one. You just have to know what you are looking for!

https://www.lifewire.com/validate-md5-checksum-file-4037391 But if you copy / paste the MD5 checksum from the documentation pages I linked into google, you are guaranteed to find the correct bioses. After downloading check if the files have the correct name according to the documentation. Then place the bios files in the "RetroArch\system" folder.

@RaiderX1212 Don't forget what I wrote here. This is very important.

From the documentation pages you can copy / paste the MD5 checksum into google. You will find the correct bioses.

Beetle Saturn documentation Genesis Plus GX documentation In the core options of both cores, for "System Region", you must choose "Auto" or "Auto Select". *Edit* To be clear. The bios files do have to be named exactly as described in the documentation. Even the MD5 checksums must match.

This RetroArch docs page lists all the bioses you need for arcade emulation with the Flycast core. Like neil9000 mentioned, the easiest way to find them is in a (recent) Mame romset. But google will do too. Just make sure the bioses are fairly recent and naomi.zip contains the romfiles listed in neil9000's screenshot. Place the bios files (zipped) in the RetroArch\system\dc\ folder.

I am guessing you have added Doom to your Windows platform. If you change the platform to MS-DOS, LaunchBox scrapes the 1993 version. Note: In the link you posted to the LaunchBoxDB, the platform is also listed as MS-DOS.

LOL. Game on!

Make sure that in LaunchBox > Tools > Manage > Emulators > RetroArch, you have "Extract ROM archives before running" unticked. And that in the "Associated Platforms" tab you have the platform name exactly as you've named it while importing your games. Then make sure the appropriate core is selected.

LaunchBox does have a debug log. You can turn logging on in Tools > Options > Debugging. The log is written to LaunchBox\Logs. But do you have multiple Mame installs or Mame rom folders? Because in that case I would triple check if LaunchBox points to the correct Mame install and mame.ini points to the correct rom folder. If you have multiple Mame rom folders or Mame installs it's easy to mix them up. Also, mame 0.238 is new. Did you have this problem before updating / upgrading? *Edit* To clarify why I ask about multiple Mame installs: you stated the location for mame.exe as C:\Emulators\Mame. But your screenshots show ..\mame_0.238. (Maybe just a typo but it can't hurt to check.)

Maybe it has something to do with the order in which LaunchBox sends the command-line for the core / extra command-line parameters / game path to RetroArch. But hey, if it works, it works!

From running RetroArch in a command window with the -h switch: -c, --config=FILE Path for config file. Defaults to retroarch.cfg in same directory as retroarch.exe. If a default config is not found, the program will attempt to create one. --appendconfig=FILE Extra config files are loaded in, and take priority over config selected in -c (or default). Multiple configs are delimited by '|'. I myself use (for example): retroarch.exe -L "cores\flycast_libretro.dll" -c "config\flycast_libretro.cfg" or

I just downloaded a Dreamcast game in .cdi format and it imports just fine. I use RetroArch for Dreamcast emulation, but the emulator does not matter for the import process. As I already added the game to the correct folder where I keep my Dreamcast games I selected "Use files in their current location". As you see here, LaunchBox picked up the game just fine.

I do not remember what the defaults are. But yes, in BigBox you can select what image type to show. Also BigBox adheres to the media priorities you have set up in LaunchBox. But if I'm not mistaken, the image type shown can also be theme dependent. Some themes might only support 2D boxes.

I forgot to mention. If you have a licensed version of LaunchBox, you can set up the image priority in Tools > Options > Media. Here you can set up the order of which image groups LauchBox should display if you have missing media.

Look for "Image Group" in the LaunchBox top menu bar. Most pc games have a quit or exit menu option in the main menu, but those who don't usually exit with Escape or a controller button (B) from the main menu. I have one game that exits with the q key. In that case I use a keymapper (JoyToKey) to map the q key to my controller. (Although I could use a script that sends a q keystroke, so it will still close in the intended way.)
