Yeah i have seen the same actually as well.

Ill let Jason be a bit more diagnostic here as he obviously knows the code, but it sounds more like a firewall/antivirus issue to me. Its getting so far before its blocked from internet/quarantined by AV. Its not a issue i have seen come up before that i recall so does sound limited to your specific system. Are you running any third party firewall or AV tools at all?

Yeah that wont work, you will need a version of actual MAME for your version. The MAME importer has been re-written for 11.9 and now allows you to accurately import any romset version, but it needs the emulators matching version itself in order to get all the info it needs to filter and import the roms. New Feature: The MAME full-set importer is now MAME-version agnostic and will work much better with older or bleeding-edge MAME releases (manual MAME updates on the LaunchBox server are no longer required)

Are you actually using MAME as the emulator, or are you trying to use a Retroarch core?

Right click it and "open with" notepad or notepad++.

With the new Plex Arcade you still have to go and download the cores, so not really any different to Launchbox in that regard, this is due to licensing reasons, you cant supply retroarch or its cores with a paid product. Launchbox has a paid option, and in order to use the Plex Arcade you have to pay a monthly subscripion, $2.99 for existing Plex Pass users, or $4.99 if you don't have a Plex Pass subscription, so due to the license Retroarch uses it cant be provided with products that charge for there use.

This.

Also, struggling to read through your bad original image, as it has a awful shader on the whole screen.

WOW, really?

no mame rom should ever have a - in it, all mame roms are lowercase letters and numbers only.

There is no such rom called 1943-2.zip, thats why, you are trying to load a non MAME rom there, where did you get your rom pack from? If you right click that game in Launchbox and go to edit/launching what is the path and file there?

Also uncheck the "dont use quotes" and the "use file name only" checkboxes in your third image, those should not be there for MAME.

copy the mame.ini from the ini folder to the root mameui folder.

Because your romset version has to match the emulator version to actually be compatible, and also the MAME2003 romset is probably the most popular set there is as its compatible with a ton of devices unlike the most up to date sets. Everytime MAME updates it gets harder to run as the emulation becomes more accurate, so there is a very good reason to support older romset versions. For this very reason every release of the MAME emulator ever is available for download on the mamedev website.

Retroarch already has a option to auto load save states in the UI.

This doesnt make any sense at all, Launcbox cannot control the resolution of external programs like that unless they can be via command-line, and you have specifically added said command. I have a 4K TV also and retroarch loads at 4K if that is what Windows is set at (although i actually have Windows set to 1440p so i can get 120hz, and Retroarch loads at 1440p just fine). You have something else on your system interfering i'm afraid.

You can add systems, just double click the empty cell at the bottom of the list. As for Beetle, it's only called that in the Retroarch UI, the actual core is Mednafen_Saturn.

Sort of true but not exactly. Obviously they are designed to make money, thats a no brainer, but they by law have to pay out a certain percentage of money taken. This can usually be adjusted by the machine owner, but can only be adjusted within a built in range, a owner couldnt make it 1% payout for example, as that would be against gambling laws, sort of why there is such a big discussion about thigs like FIFA packs that offer random odds of less than 1% and are purchased with real money.

Maybe that whole list should be "Skip" then alphabetical order???

The problem there is Launchbox extracts to the temp folder and not where your roms are, so on the second launch it will just look at your specified rom path for that game again, and the temp folder is removed when you close Launchbox. At the end of the day this would be a waste of space as you would have two copies of the same game, one zipped one unzipped. So in that case why do you have the roms zipped in the first place? just extract them and cut out the middle man.

Yup, good spot.

Sounds like a waste of money if its deleting perfectly safe files if you ask me.

You will need to contact the criminal that sold you all this stolen content for support i'm afraid, we wont be providing any support here.

Uncheck the "remove roughly matched images" option in the import wizard. That examines every image downloaded for every game to see if they are duplicates, and takes a very long time to do.

Thats a video file isnt it? Its not a startup theme, if you want that to play as you start Bigbox it needs to go in your Launchbox/Videos/startup folder.
