When you edit your RetroArch emulator in LaunchBox, in Associated Platforms next to the platform name you have your selected core_name to use for that platform. RetroArch needs -L to prefix the core_name. Next to that are the parameters you want/need to use for that platform. Depending on what checkboxes you have checked in the Details section, when you launch a game, LB will suffix the command with "full/path/to/rom.ext" or rom or a variation there-of. The parameters and ROM_file need to be encapsulated in quotes. Put that all together and you get: -L core_name "parameters rom" or if you use the full path, no quotes -L core_name "parameters \"full/path/to/rom.ext\"" Note that the quotes added to the full/path/to/rom.ext need to be escaped (forward slash). Using Atari 2600 as an example, from the Window Command Prompt, you'd type retroarch.exe -L mame_libretro.dll "a2600 -cart \"D:\ROMs\Atari 2600\frogger.zip\"" Or just follow what @sundogak wrote. (he types faster than me )

jplstw22.zip didn't import because it's for a 'Mechanical' Pinball machine (but sounds like you eventually un-checked Skip Mechanical Games). And for that same reason, it unplayable in MAME. For The Lost World: Jurassic Park, the ROM (in your full set) you're looking for is lostwsga.zip. But using the MAME Arcade Import Wizard, that won't import either because it's Unplayable in MAME (unless of course you un-check Skip Games That are Unplayable). The emulator you want to use for that game is Supermodel (a Sega Model 3 emulator). You will also need the Device file segabill.zip (also found in your full set).

This may help with what you're wanting to do.

Emulators and Their Games / Platforms and Their Emulators View File View all games associated with an emulator. Can't remember which games in your Nintendo Wii platform use the Dolphin emulator and which ones use the Dolphin-TriForce branch? Use this plugin see which games are used by a specific emulator. Setup: With LaunchBox NOT running, download and copy the **contents** of the 7z (zip) file into you /LaunchBox/Plugins/ folder. i.e. D:\LaunchBox\Plugins\Emulator-Games\Emulator-Games.dll Using: Stat LaunchBox Click Tools Click Emulators and Their Games Select an emulator to see a list of all games that use that emulator. If a game uses the selected emulator but is NOT in one of its Associated Platforms (go figure how that happens. ), it will appear in Red. A list of Associated Platforms for that emulator will also show. Click on one of the Associates Platforms to view only games that use this Emulator AND are in the Platform. Click Reset to go back to showing All games using the Emulator. To create a Playlist of the games shown, click Create Playlist. The Playlist will automatically be given the name of the selected Emulator. (Change it to whatever you want) If you had selected an Associated Platform then clicked Create Playlist, the auto-fill name will be "emulator (platform)". The playlists will be added to Platform Category "Emulator Games" As always, all comments and suggestions are welcomed and encouraged.

Yeah, it's not yours nor the LaunchBox Games Database's fault. This has been fixed in v1.2.7. Download the latest release (top of this thread, View File) and let me know if you have any further issues. And thanks again for letting me know. Version 1.2.7 - Fixed: Games that don't have a Release Date cause the plugin to crash. (Introduced v1.2.6)

I which I could blame it on The Matrix, but it's a "glitch in the" last release. It has to do with the "Improvement" that attempts to match to the game's Title and Release Year. If your game doesn't have a Release Year in its metadata, the plugin 💥 blows up. Thanks for binging this to my attention. I'll have my team 'get on it'.

When selecting multiple files, then start the plugin, you still need to go through them one-by-one (use the << and >> buttons to go to the previous/next game). If the game doesn't find an exact Title match, you will see a popup where you can select a 'close match'. (Same thing as if you start the plugin with just one game selected.) When having started with multiple files selected, you can optionally click "Just Grab 'em All". Select the image type and size and click Start. For 'Grids' Try selecting "600x900" (the most common size). If no images of your selected size [and type] are found, well... it won't download anything. If that doesn't help clear things up, can you be more specific with "it will do nothing"? Are you saying you select multiple games, then right-click one of them and select "SteamGrid Scraper", nothing happens? As in, the plugin window doesn't even appear? I suspect you mean edit the 'Game'. The plugin won't (and can't) delete existing files to replace them. So if you have an existing Clear Logo and you download another one using the plugin, you'll have 2 [for that game]. When you have more than one image of a specific type (say, Clear Logo), LaunchBox will randomly alternate which image is displayed. So if you click a different game, then back to the one with 2 Clear Logos, the 2nd image may show. If not, do that several times and it should eventually appear. If it never does, then it's possible LaunchBox doesn't alternate Clear Logos like it does other images (i.e. Box-Fronts, etc.).

For emulators that are geared towards MAME ROMs from a specific source, you can use the Advance Search functionality to filter those out, then 'select all' and then either, bulk-add a Custom Field or bulk-add to a playlist. i.e. For Sega Model 3 (Supermodel), in Search type in source:model3. (Where here, the source is model3.cpp) Maybe not an end-all, cure-all. But a start, nonetheless.

Thanks for the update. Any chance you've been testing between 2 emulator setups? (Same .exe, but 2 different entries in LaunchBox) In an earlier screenshot, your emulator name in "Demul". And in you latest one, it's "Demul (NAOMI)". Regardless, glad your method is working for you! Now go play some games.

I tested Border Down (bdrdown.zip), Cosmic Smash (csmash.zip), Giga Wing 2 (gwing2.zip) and Power Stone 2 (pstone2.zip). Border Down was the only CHD-required game tested. All 4 worked without issue when launched from LaunchBox. But I could NOT get them to work with Remove File Extension and Folder Path and Remove Space Before ROM un-checked. They did work with Remove Quotes either checked or un-checked. Beyond my screenshots above (with the noted exception for Remove Quotes), based on you saying they do work when ran directly from DEmul, the only thing I can add is make sure the ROM paths [in LaunchBox] are pointing to the root ROM files (the .zip files) and not the CHD files in their respective subfolders.

Sorry. I missed this in your previous post. Do NOT check Extract ROMs. Also, is Sega Naomi the only platform you have Associated with this emulator? If you have more than one Associated Platform(s), you need to put that command line parameter in for that associated platform. And then, of course, the respective parameters for the other platforms. If it is the only platform associated with this emulator, you can leave it as you have it shown in the Default Command-Line Parameters. Just un-check Extract ROMs.

Looking at the Sample Command in your 1st screenshot, you end up with 2 sets of double-quotes. Remove "%romfile%" from you default command-line parameters. Check the other 2 boxes ('remove quotes..' and 'remove path and files extension'). Keep the 3rd checkbox ('remove space') checked. If it still doesn't work, you need to setup the paths to the ROMs inside Demul itself.

When in the Arcade platform, press Ctrl+N. Type in the games Title. In the Launching section, Browse to where the ROM is located and select it. Click OK to save. If it doesn't appear in with your other games, make sure you don't have 'Hide games missing media' (worded something like that) checked. It'll be in the View menu.

I keep a full non-merged set and update monthly. And from the same folder, have a curated set of games imported into LaunchBox. After a MAME update, I read through whatsnew.txt to see if there's anything new I feel should be added. If there is, I just manually import those ROMs to LaunchBox.

Ahhh... pick/scan a game from the bookshelf and 'blow on the cart' to get the dust out.

What a cool concept!! Sometimes when feeling hands-on-nostalgic, I want to look through my [physical] collection on the bookshelf, pick a game from there and play my backed-up copy on the PC. I never even fathomed being able to scan the box/case/cart/disc/whatever-medium and have it load, ready to play. Too cool!

There's no built-in way to bulk add additional apps to multiple games. But there is a third-party plugin that can help with that.

In short. No.
