LaunchBox XML Cleaner (great for MAME merged roms) (keep entries for games that you have) View File Latest version and support here : https://github.com/gravelfreeman/launchbox-xml-cleaner --- This script cleans a LaunchBox platform XML so it only keeps entries for games that actually exist in a local roms folder. It is especially useful when a MAME platform XML was created from `MAME Arcade Full Set...` import but your local ROM folder only contains part of that set, and you want the XML reduced to the games you actually have while still preserving additional applications (clones) from merged romsets. LaunchBox's Scan For Removed MAME Roms... feature removes clone entries from merged sets because those clone files are stored inside the parent rom.zip. Although it was designed around this MAME workflow, it can also be used with other LaunchBox platform XML files. What It Does The cleaner scans the current ROM folder and compares it against the provided LaunchBox XML. It keeps a game when a local ROM exists for that game, including: - the main Game and ApplicationPath - any linked AdditionalApplication entries for the same GameID After the main game pass, it removes orphaned metadata entries that no longer belong to a kept game: AdditionalApplication GameControllerSupport AlternateName How to Use Paste a <Platform>.xml file in it's corresponding roms folder Paste _LB_XML_Cleaner.ps1 and _LB_XML_Drop.cmd files in the roms folder Drag and drop the Platform.xml file onto the _LB_XML_Drop.cmd launcher Command line If you prefer using command line, run the PowerShell script directly and point it to the XML file and ROM folder you want to validate. powershell.exe -NoProfile -ExecutionPolicy Bypass -File ".\_LB_XML_Cleaner.ps1" "C:\Path\Platform.xml" -RomsPath "C:\Path\Roms" powershell.exe -NoProfile -ExecutionPolicy Bypass -File ".\_LB_XML_Cleaner.ps1" -XmlPath "C:\Path\Platform.xml" -RomsPath "C:\Path\Roms" powershell.exe -NoProfile -ExecutionPolicy Bypass -File ".\_LB_XML_Cleaner.ps1" -PreviewOnly -XmlPath "C:\Path\Platform.xml" -RomsPath "C:\Path\Roms" powershell.exe -NoProfile -ExecutionPolicy Bypass -File ".\_LB_XML_Cleaner.ps1" -OutputPath "C:\Path\Cleaned.xml" -XmlPath "C:\Path\Platform.xml" -RomsPath "C:\Path\Roms" powershell.exe -NoProfile -ExecutionPolicy Bypass -File ".\_LB_XML_Cleaner.ps1" -InPlace -XmlPath "C:\Path\Platform.xml" -RomsPath "C:\Path\Roms" Flags - `-XmlPath`: LaunchBox XML file to clean. Can also be passed as the first positional argument. - `-RomsPath`: Folder containing the ROMs or CHDs to scan. - `-PreviewOnly`: Run the cleanup without writing any file. - `-OutputPath`: Write to a specific output path instead of replacing the source XML. - `-InPlace`: Replace the source XML directly. If `-OutputPath` is not provided, the default behavior already performs a safe backup-and-replace workflow. - `-RomExtensions`: File extensions treated as ROMs. Default: `.zip`, `.7z`, `.chd`. The script never modifies or deletes files or folders. It only reads the folder content and writes a new XML based on local roms. Submitter Light Sock Submitted 03/09/2026 Category Platform Media  

I simplified the AHK script and fixed all issues from this thread in this tutorial : Probably works for other emulators like PS2, etc.

Hey, just sharing a quick tutorial because, I spent a few hours making this work. Basically I'm using Retroarch for most of my emulators and shaders. Especially the koko-aio crt shaders that are in my opinion the most immersive and realistic. The issue is that some consoles doesn't have a retroarch core yet making it impossible to add shaders. Fortunately someone called mausimus created an open-source app, ShaderGlass, which overlays any glsl or slang shaders on top of pretty much anything. Sounds fun, but it doesn't work as simply as you'd want. Here's how I made it work : 1. First you need a working Xemu emulator configurated. 2. Now let's modify some Xemu parameters : First, under Display tab, you need to disable fullscreen and fullscreen on startup : A little further down the page you'll want to set the display mode to Stretch and set the aspect ratio on Native : 3. Now you'll want to install the latest stable version of ShaderGlass from their official GitHub : https://github.com/mausimus/ShaderGlass/releases You can then import any missing RetroArch shaders like the missing koko-aio that are fullscreen : Set the input mode to Clone : Save your setup as a custom profile, call it something like xemu.sgp : 4. Now in Launchbox modify your Xemu emulator and remove the -fullscreen flag in the command-line parameters. Should be looking like this now : 5. Now, still in LaunchBox's Xemu emulator options, replace the Running Script by (update paths accordingly) : WinWait, ahk_exe xemu.exe WinWaitActive, ahk_exe xemu.exe Run, D:\LaunchBox\ThirdParty\ShaderGlass\ShaderGlass.exe -f D:\LaunchBox\ThirdParty\ShaderGlass\presets\xemu.sgp Sleep, 1000 WinActivate, ahk_exe xemu.exe WinWaitActive, ahk_exe xemu.exe WinWaitClose, ahk_exe xemu.exe WinClose, ahk_exe ShaderGlass.exe Basically what it does is simply : Wait for Xemu emulator to be ready Run ShaderGlass fullscreen with your profile Give back the focus to Xemu so that your controller works When Xemu end, exit ShaderGlass You would think it's done but unfortunately you still require borderless gaming to get Xemu fullscreen without being actually fullscreen. Otherwise your shader will clip on both sides and look like this : 6. Install the legacy open source version of Borderless Gaming which is still working great up to this day on Windows 11 : https://legacy.borderlessgam.ing 7. Add Xemu to your Favorites which means it's going to fullscreen window the app automatically : 8. Check Run on Startup under Options dropdown. Now everything is automated and working! You might wonder why I'm not using ResizeRaccoon which does the same thing? I tested it and it's working if you're not using BigBox as Windows shell instead of explorer.exe. In my case I'm shelling bigbox.exe so Resize Raccoon doesn't work because it's a system tray only app. It would be great if the dev fix this but I don't have time right now to raise an issue on their Github. It would be best in the future because it's open source compared to borderless gaming which is now paid. By the way this is working perfectly in BigBox. Enjoy!

Hey @Retro808! I was wondering if you have any news about this feature request? Guess I should've dig this further a few years ago when I stumbled upon this issue. I tried today on the latest nightly and it's still not implemented. This time I'm kinda sad because I've put quite some time in a theme thinking it was possible to do. But the option was only for Platforms and not about Platform Categories. Basically I want to use this view for Playlists/Decade/Genre : And this view for actual systems : Same view after 4 seconds : I was about to create a dedicated view for the root where all Platform Categories are shown. But it's where I found out the Platform Category views weren't saved per category. I would like to upvote this feature. Thank you!

Hello, I've been using LaunchBox and BigBox for many years now and I'm the creator of the Arcab theme. I'm currently taking on the development for the Slipstream theme which have been abandoned by it's creator. I think he's now working on creating his own front-end. At least that's what I understand from his latest messages. Sorry if that assumption is wrong. BTW I'll have the theme's source code on Github for anyone to contribute in the future. One thing I always had issues with BigBox is that there's no way to use the alpha channel in videos. I wanted to make Slipstream more clean by integrating @viking's system videos. It's great because he shared all of the source AE and PS files. It was easy to remove the coloured background that ties the files to the Colorful theme which doesn't work in other themes. At least as a graphic designer, it would require something very specific to make a great match. I'm currently using his platform images pack which he kindly took the time to make available for us theme creators. Unfortunately everything I tried didn't work in BigBox. I'll share what I tried if @Jason Carr you're open to integrate this. BTW, I'm willing to re-export all viking's work in 4K resolution, 1:1 aspect ratio and alpha channel. This would be a great opportunity for theme developers out there. 1. WEBM Support - https://www.webmproject.org/ Pros is that the file size is much smaller than any other formats. VP8 codec would be great because it requires less time to encode. VP9 would be the greater option since it outputs better quality videos with smaller size. Tried both codecs in BigBox and the alpha channel is filled with white/black color. It's compatible with K-lite and VLC, so I think it wouldn't be complicated to integrate. I tried both with K-lite and VLC getting same results. I would vouch for this format since it's made by Google and it's open source. I don't believe this format will disappear anytime soon. 2. Quicktime Support I tried it out of curiosity because it's what we use in the industry when dealing with alpha channel but this makes huge files since it's meant to be used primarily for production. It does work in BigBox but the alpha channel is replaced with a matte black. In other words, everything under the video can't be seen aka doesn't work. I tried both with K-lite and VLC getting same results. Maybe there are codecs I'm not aware of that outputs smaller size files but I never tried it. 3. Filename Based Image Mask Support If for whatever reason it's not possible to support alpha channel through above methods, perhaps performance issues, etc. The last thing I'm thinking of are image filename based image masks. I tried it by making a mask of everything apart of the actual video layer, exported, added mask and voila! I can "technically" get the equivalent of a "transparent" video in BigBox. Thing is that the image mask will be the same for any platforms which is problematic because not every platforms are the same. So it does work for one platform but, that's it. A simple workaround would be hard coding in BB to check for a .png of the same name of the platform video. If present, it's getting automatically applied as an image mask respecting perfectly the alignment of the video for a perfect match. This idea isn't the best because it would have fair amount of limitations compared to just supporting WEBM format. Plus it's adding more code to support in LB. 4. GIF Will post soon the Slipstream theme.

This is kinda time consuming though! Someone shared an app here on the forum. It parses the xml with all the games and let you sort by rating. I found it after so I had found another way around which might work for someone else. Basically you download a torrent with the fullest and set qbittorrent to pre allocate files. Even if it’s at 0.01% you can stop the torrent and all the roms will be there with their correct name.zip. These can all be imported just like if you had the games. Basically LB can’t tell they’re pre allocate dummy files. Since I kept only like an hundred or 2 it was easy to check them in qbittorrent and only download the ones I want.

That one was confusing! It would be really great to have the choice of the conditions logic. AND/OR is basic and would save a lot of time. For example Disney isn't in every Title. So I would like to have Alternate Name Contains Disney AND Title Contains Disney
