Hey there fellow Launchbox Devs, this is my first attempt to develop a plugin that attempt to read all zip files in a a rom folder recursively and create a new Platform and Games for those. So far I've setup the full .NET 9.0 development environment and confirm LB can load this plugin and I can see it in the Tools menu. What's strange is despite calling `PluginHelper.DataManager.Save()` after `AddNewPlatform` and `AddNewGame` I don't see any XML created. I've checked the Plugin docs but couldn't find anywhere that mention how to save other than this. A snippet of the code. public void OnSelected() { var platformName = "JAKKS Pacific TV Games"; var romFolder = @"c:\temp\mame_curated_romset\jakks-pacific-plug-and-play-tv\"; // Your curated folder IPlatform platform = PluginHelper.DataManager.GetPlatformByName(platformName) ?? PluginHelper.DataManager.AddNewPlatform(platformName); platform.SortTitle = platformName; //platform.Save(); foreach (var file in Directory.GetFiles(romFolder, "*.zip", SearchOption.AllDirectories)) // This makes it recursive { var fileName = Path.GetFileNameWithoutExtension(file); IGame newGame = dataManager.AddNewGame(fileName); // STEP 4: Set game properties newGame.Platform = platform.Name; newGame.ApplicationPath = @"C:\MAME\roms\bubblebobble.zip"; newGame.CommandLine = ""; // optional newGame.EmulatorId = dataManager.GetAllEmulators().FirstOrDefault()?.Id; // optional newGame.Version = "Softlist"; newGame.SortTitle = "Bubble Bobble"; PluginHelper.DataManager.Save(); } MessageBox.Show("Import complete!", "JAKKS Importer", MessageBoxButtons.OK, MessageBoxIcon.Information); } public bool ShowInLaunchBox => true; public bool ShowInBigBox => false; public System.Drawing.Image IconImage { get { return Resource1.logo; } } public bool AllowInBigBoxWhenLocked => throw new NotImplementedException(); } Edit: Solved. Turned out I just have to refresh the menu! This will be a first step for a plugin to come that will handily import a curated MAME MESS list.

As a long time licensed Launchbox / Bigbox user i want to give you my thougths.... Maybe i am to critical but i think it is beneficial for developers and all users to have this discussion. I love Lauchbox / Bigbox however.... There are some serious performance and stability issues. Last week i have been doing fresh installs on my 2 cabinets with a lot of problems. One was with a fresh windows 10 install and one was with a half year old windows 10 install. First the performance. It is really really bad right now (12.6). As mentioned in other posts sometimes the menu's react very slow. Seems the longer you run launchbox the worse it gets. As i read in another post there is a 12.7 beta that sort of improves the problem. The word "improve" in the post triggered my attention. Sometimes the menu hangs for 10 seconds. This is not an improvement but a bug. I have also seen for years now that graphics load very slow in big box when you enter a large system like mame. If you scroll to the letter S for example the wheel art loads very slow. Sometimes it takes a couple of seconds to load the wheel art and sometimes it takes 10 seconds or more. I have never seen this poor performance on other front ends. It is not that i have seen this once. Have seen it over the years on many installs. Second the stability. I have seen different stability issues over the years. Now with my 2 installs i encountered: A couple of system freezes. On both cabinets. I have also seen that when launchbox is downloading media and you close launchbox it should resume downloading after you restart it. Most of the times this works. Not always however. I also notice that after importing games downloading media is a hit or miss now. Some other problems that i have forgotten My PCs should be more enough to run a graphical front end: CPU >> Benchmark score of around 5000 on passmark GPU >> GTX 950 RAM >> 8 GB My thoughts. It feels to me like the development of Launchbox is heavily skewed towards developing extra features instead of focus on performance and stability. It feels like we are building the fifth roof on top of a house where the foundation is crackling. Maybe the developers can send out a poll to all users and check if more people experience this. They can ask where the focus should be on the coming year, on Features or Performance/Stability? I am not a coder but the performance of other front ends suggests that better performance should be possible. A raspberry pi can run a decent front end like ES. Maybe the coding is done in a language/environment that asks for too many system resources? Maybe Launchbox itself is too complex? I do not know. Maybe it is a good time to make a fresh start? Maybe not. When you do I would choose the most efficient coding environment and i would start with basic features everyone needs. What is the most important? Add that and make the core stable with high performance. Evaluate what is not important and can be left away. I can think of a few important basic core things to focus on like: Importing systems/rom sets Automatic downloading of media/videos Settings up the emulators Sorry again for the critical message...... I love LB/BB for the easy of use and active development. I hope we can add performance and stability in the near future!
