Try copying your mame.ini file that should be located in the ini folder into the root folder where the mameui.exe file is. This issue started around 0.186 and that was the fix.

Glad your sorted. Just remember anytime you add a new platform make sure it is listed in the emulator you are using under the associated platforms tab.

Should look something like this. Your name of the associated platform make sure it matches how you have it named in Launchbox. The -run=dc -image= does not need to be in the emulation details tab since you have it in the associated platforms already. I don't put it in that tab since I use Demul for Sammy Atomiswave and Sammy uses a different paramater.

I do not see that you added the other two platforms in your associated platforms tab. Since you added platforms called Sega Dreamcast (homebrew) and Sega Dreamcast (imports) those also need to be listed under Sega Dreamcast in the demul associated platforms tab. Otherwise Launchbox does not know to use that emulator for that platform.

So if they run direct in demul there is a disconnect somewhere in Launchbox. Can you share a pic of your manage emulator screen showing the emulator details tab and the associated platforms tab. Also right click, edit a homebrew game and share a pic of the launcher and emulation tab.

In launchbox did you add these to the associated platform of your Demul emulator? In the image below you should also have those two platforms listed so launchbox knows to associate the new platforms with demul. Use the same command line parameters as Dreeamcast too. Also make sure the associated platform name matches exactly how you have the name of the platforms in Launchbox.

The homebrews should work as well. I just tested a couple homebrews and they work fine through Launchbox in Demul. When you say most games work do you mean normal Dreamcast games? Did the homebrew roms get added to the same platform in Launchbox as Dreamcast games or did you create a new platform for the hombrews and imports?

They both work well and definitely a preference thing. Mame is actually a breeze. Just point it to the folder where the roms are, make sure in the roms folder you have the coleco bios zip and make sure you have the following command line in launchbox associated platforms tab for ColecoVision: coleco -cart

Are your drivers update? I have two machines one with a dual monitor and another with a triple and in each set up the monitors are all set to their recommended resolutions and have no issues with LB displaying correctly. I am not an expert in this area just sharing that it should work as you would expect. On my dual monitor one I had this issue but when I upgraded the GPU and then upgraded of course the drivers to go along I no longer had the issue.

@snarfo67 Don't sweat it. Like @neil9000 said we have definitely seen it before. Missing quotation mark, 3 L's in .dll, missing space, missing "-". You are sorted that is all that matters.

That core no longer exists. It is recommended to use standalone Mame. I would take a look at this post. The bios for coleco when used in Mame will need to be zipped.

Same here as @Lordmonkus Windowed Fullscreen set to off.

yeah I have the iPac. The Xarcade is a keyboard as well so I am not sure why the normal Mame configuration in RA is not working for you. Can you post a couple pics of what a game looks like and pics of your video settings? Maybe I can replicate it on my test pc.

I would download a new RA and put it in a different folder. then download only the Playstation core, copy your bios into that folders \system folder and test. If it works well then you know something is corrupt in the original folder.

If you go into the \cores folder of your Retroarch do you see the core .dll there? Should be something like mednafen_psx_libretro.dll If it is showing in RA in your list of cores to load it should be but just figured check in case.

For PS1 you just need to make sure you have the correct bios in the \system folder of your Retroarch structure. There are several out there SCPH1001.bin (I think this is the older PSX bios), SCPH5500.bin, SCPH5501.bin, SCPH5502.bin you need the correct one for your roms.

Welcome to Launchbox and the forums. Edited: I see @neil9000 beat me to the punch again We recommend setting up RA and making sure your roms all work before importing into LB. That way if it does not work after import it is easy to tell if it is a Launchbox issue or an RA/Roms issue.

You should probably share what type of encoder you are using than so those that have the same one will know to do what you did. With my iPac and the Xarcade I simply launch a game and hit Tab and set everything up just like I would in standalone mame. Under the \saves\Mame folder RA will generate a default.cfg as well as inidividual game .cfg files if you set specific machine controls. RA retains and launches those controls regardless of what is set in the RA input menu. For the aspect ratio I cannot say. I have mine set to core provided and no matter what game I launch it launches as it should. Are you using a custom aspect or just "core provided"?

Works fine with my arcade cabinet controllers. The bartops and the standup.

Definitely something missing in your Launchbox set-up causing a disconnect. I did not have C64 loaded in my arcade but I just set it up and tested 2 games and they launched fine through Launchbox. I would say post a couple pics of the Emulator Details tab and Associated Platform tab from the manage emulators screen just so we can see if we notice anything.

I would also recommend hoping onto their reddit/forum/discord and reading/researching as Cemu requires tinkering. I have been recently messing around with specific game graphics packs as some are non-resolution fixes and their site has been helpful in navigating through all the tinkering you can do.

@faeran Another great addition to your theme set. Keep 'em coming!

I use the below script anytime I have issues closing and need an AHK script to close. Currently have it on a few emulators on my test pc and It closes well with no pop up error showing up. The delay allows it so random button mashers do not accidentally close the emulator when playing. This is set for my 8Bitdo "Select" (hold) and "Start" (action) buttons so you would have to figure what your controller buttons are. Joy11:: If GetKeyState("Joy12") { SetKeyDelay, -1, 110 Process, Close, {{{StartupEXE}}} } Return

That's what @neil9000 was advising. You can have game details screen off as default and then set a key for it in BigBox. When you launch a game the details will not show. When you scroll and stop on a game if you do want to see the details to remove or add to favs you then just hit the key you set. This gives you the option to only see the game details screen if you hit the key you set. Otherwise it will not be shown if you just launch a game.

Steam import is currently broken with Launchbox right now. There are a few threads in this subforum on the issue. Here is a recent one. Hopefully a decision on the issue will happen soon.
