I can confirm you that mGalaxy is working on Windows 10 ;)
Try to be more precise what's not working for you? What it working before 10.1?
When you say 'Can not add new system', do you mean you are in the 'Systems' tab, click 'Add system'...and no window open?
When you say 'Can not update rom', do ...

how did you know about needing the second (CD32) and third (CDTV) file? it's not mentioned in the emulator section of runway... ? is it in a helpfile I've not read ?

To help you, I first wanted to check if I could get everything to work with a .bat file using the command line...and when I went ...

Actually, looking at Emulators.xml inside the 'Data/Definition' folder we can see this:
<Emulator name="WinUAE" hidden="false">
<Systems>
<System name="Commodore Amiga" option="" script="false" cmd="-config=mGalaxy.uae -0 &quot;%path%slash%file%ext&quot;" extensions="adf|adz|dms|fdi|gz|hdf|hdz ...

...because you need to have a Premium license to unlock it!

This is not my case, sorry...but in another post I advised you to try to run it in compatibility mode, did you try it?

This should be due to the pixel filtering setting, which is activated by default.
To request that this filtering not be used, specify it in the command line sent by mGalaxy.
To do this, go to the mGalaxy folder, then the Data folder, then Definition , then open the Emulators.xml file with a text ...

Sorry to ask, but you do have an account registered in the database and entered in mGalaxy? 

After moving my arcade and once on an windows update, windows reordered my controllers. I’ve used devreorder but I cannot control which of the attachments mgalaxy uses for its menus etc. It decided ‘no joystick’ but is probably selecting my guns 💪. If there a way to stipulate them?
I think that ...

Also anyway to slow down the scraper as it’s going so quick it’s maxing out the threads?
I can't reproduce what you're talking about.
In my experience, the only reason the scrape might stop after a few games is if you haven't registered on the screenscraper site...and/or if you haven't entered ...

In my opinion, there are two possible explanations:
The first one (independent of mGalaxy): since then, you use a different version of Mame, without the romset you use being up to date
The second one: when creating the database in mGalaxy, some filtering options are proposed, you can uncheck all or ...

it's systems that actually use all the butttons for something is when I run out of options

I'm not sure I understand you, are you talking about games that require more buttons than your XBox controller allows? Strictly speaking, this is not an mGalaxy issue!

Guillomm69,
I was asking a question that was never replied there: https://www.mgalaxy.com/forum/https://www.mgalaxy.com/phpBB32/viewtopic.php?t=0...is it the same concern?

Bien que je ne connaisse pas Demulshooter je veux bien tenter de t'aider mais j'ai besoin de savoir ce dont tu as besoin exactement.
D'après ce que je vois (https://github.com/argonlefou/DemulShooter/wiki/Usage) on envoi à Demulshooter, par ligne de commande, le chemin vers l'application et le ...

Maybe you could try this:
Open mGalaxy/Data/Definition/Emulators.xml with a text editor
Do a search on "MAME" untill you find this line:
<Emulator name="MAME" hidden="false">
then, replace "false" by "true"
Save

From what I understand, this parameter is supposed to set the visibility of the ...

I don't think mGalaxy freezes. I had this discussion with mGalaxy himself: mGalaxy is simply in a waiting state while the launched process is still running.
In clear, mGalaxy starts a process (MAME) and then waits for it to be terminated in some way!
I'm really confident that the problem comes from ...
