This is a different problem and can be caused by several things: Are you sure its a Naomi game, not a Naomi 2 or a Sammy game. Does that game need a corresponding CHD image as well? Some games you have to use the service key to go into the settings of the actual arcade game and change things like cabinet type to work corretly. Can you specify the game you are trying? Are you sure LB is pointing to the same Retroarch install as when you start it manually?

I went ahead and tried it and it did respect the previous Show/Hide settings. The only additional games that appeared are newly working ones. Even more important, roms that I had set to use a different variant/clone as default, stayed set that way, Need to make sure I still can pick characters for those 4 player games, TMNT for example. ?

Try setting it manually to the specific system type and make sure to save a game specific option override. (top item in that same menu) Than restart the game. You mentioned you grabbed the rom from a mame set, was that a current set? (Or close to it?) Just to be safe, Once you load the core, I would double check in the Retroarch menu -> Information -> Core Information and double check the bios checksums match as well.

Once you start a game, if you go into the Retroarch menu (F1 by default) and look under Options, is System Type set to Auto?

I initially used the full Mame importer but my displayed games are relatively small, around 400 games. I always run the latest Mame but don’t bother re-importing as very few of the roms in my collection ever change. If one needs an update, I just grab the rom from my update HD and move to my Mame rom directory manually. If I was to re-run the full Mame importer, does it respect the Hide/Show property set for individual games? I know I could make a playlist before importing and mass edit back after, but curious how the importer handles it.

Did you install Retroarch using the installer? If so you should have a debug version in the Start menu that will produce a log file that might help. (If you used the Retroarch zip, the debug version should be in your Retroarch folder)

Can you be a little more specific? Which LED should be lit that aren't. If a key isn't mapped for a specific function it won't light? In MAME, is that some games or all games? Do you have any animation options set in LEDBlinkyConfig?

Sundogak answered this on the first page, the roms don't have headers and the internal Altirra DB doesn't have a checksum for that rom either.

Are you sure you don't have the "Use filename only without extension or file path" option selected in Emulator Settings for Retroarch? Your problem didn't make sense so as a test I enabled that and guess what, all my Sammy games start the Dreamcast screen. (Makes sense since emulator isn't passed a proper filename/filepath so it defaults to DC) If that isn't the problem, I would suggest deleting all flycast configs in the Retroarch/config folder (backup if you have some custom configs saved), and trying again, including setting system type in Retroarch and saving a game options file if needed. Also, make sure your Sammy roms are still pointed to the correct location as you are manually loading when using Retroarch directly.

Sure it does. M.A.C.H. 3 status plus I use MAME for it ? Can you run it from a command line with the -v option and that should tell us what the issue is.

I think his/her issue was a little different as his/her Flycast roms were imported as a mame set and mame64.exe was set as the default emulator. Changing the default emulator doesn't automatically change the previously imported roms. (Although LB does now ask if you want to do that)

Yes all my Atomiswave games run via the flycast core. Like I mentioned, I've started each game, used the Retroarch quick menu to manually set the system type, and saved a game options file for each game. I've done that with all Naomi roms as well. Did you try setting the system for that problem game to Sammy Atomiswave and then try launching from LB again? (You have to save a game options file or that setting will apply to all games with that core)

Start a game, hit F1, there should be an Options item, there isn't? Didn't notice that. Would have to see your emulator settings for Retroarch and the associated platform tab as well. Any chance you have a custom command line option? I generally don't trust auto settings for things like that and have manually set all my non Dreamcast roms with Flycast core. Stab in the dark but but maybe Retroarch hashes against it's internal DB when loading through it GUI, and doesn't when started and from command line and passing a filename or some other difference? If your settings are correct you would think it should be the same.

Bring up the Retroarch menu and look under options and see if System type is set to auto. If it is already set to auto and it's not detecting right for a game, set the correct value for that game instead of auto (Atomiswave in this case) and in the same menu at the top save a Game options file. Now when you start that game it should switch to that system properly.

Start Retroarch and than plug your gamepad in. Bring up Retroarch menu, go to Settings -> Input -> Port 1 Controls and select Set All Controls. Do the same as you did for the keyboard but use the gamepad buttons. Once complete, select the Save Controller Profile option in that same menu. Now that profile should load automatically in Retroarch when connected. If you want to re-arrange the layout of buttons for a specific core or game, you do that in the Quick Menu of Retroarch (once a game is loaded) under controls. You make the changes you want and than save a remap (in that menu) and it will be loaded automatically depending on whether you to save it as a core remap, directory remap, or a game remap. Hope that helps.

Looks like it. More info here: P-UAE libretro github

FYI, you need to turn on game bar in Settings -> Gaming first. Are you recording full screen, or just windowed? I have yet to get it to work with Retroarch in full screen or full screen windowed mode. Edit: I just got a message that I need ms-gamingoverlay app when trying in windowed mode. My guess is this is part of the Xbox gaming stuff that I don't have installed on my cabinet.

Definitely. My dual core i3 @ 3,9 GHz out performs my old quad core i5-6500K @ 3.5 GHz on MAME games.

It's makes it simpler for importing by platform though.

I use Flycast in RA exclusively for Atomiswave and no black boxes for me. Options make a pretty big difference with this core, what settings are you using Johnny T and what are your specs?

Same for columns and batmanfr. Only played 2 rounds on vf. Only played for a bit but MAME seem to play Batman Forever on my lowly i3 just fine.

I played with this previously and since LB has LEDBLinky support, I hijacked this process with an AHK script and used the video player mpv to play a video on my marquee screen and then passed the call to LEDBlinky, I never finished it since I really didn't have the right media for it, but it would need some monitoring functions to quit if the emulator quit and things like that, but the process did work.

Yup it's that easy. Use it a lot with my iPac, one of the reasons I leave it in keyboard mode. The AHK script in the running tab of LB will end when program is done.

Not sure. A couple variants to try:

Right click on the file and choose open with Choose another app, Click more apps. and at the bottom of list you should see Look for another app on this PC. Now navigate to your Launchbox folder and look for AutoHotkey.exe. (If you are on the latest version, it's in LaunchBox -> ThirdParty -> AutoHotkey
