Hello Joe, I wanted to give an update about this weird situation. I found on my own the problem, but I took inspiration from your last answer and pics. For some unknown and weird reasons, it seems this issue happens very often (there are other threads in this forum), LaunchBox apprently does not run automatically the command -run=naomi -rom= . As you can see below this command is set in the DEMUL emulator setting, but not in all games (execpt for psyvar2, which was working with no problems). I had to put the command manually to every game, and now LaunchBox finally opens automatically every NAOMI game, despite the Setting options in the DEMUL emulator are all unchecked (Remove File Extension and Folder Path, Remove Space Before ROM and Remove Quotes). It is weird LaunchBox Team apparently did NOT take action against this very weird issue. In fact, there are threads even older than 2015, with this same issue! I hope I could help anyone else who will have the same issue. Thank you for your answers.

Hello Joe, I solved partially alone this enigma. I have to put the command, not only in 'Details" section of the Emulator (DEMUL) but alos in the 'associated platform' section of the Emulator (DEMUL): -run=naomi -rom= ON top of that, I had to UNcheck all the options ('Details" section): Remove Quotes Remove File Extension and Folder Path Remove Space Before ROM On this way, only the game psyvar2 can be opened automatically, if selected in Launchbox. For all the others Win/command prompt window shows very fast, then not even DEMUL opens up... I listed the ROMs folder (path of DEMUL), where are all NAOMI ROMs (the yellow folders contain the CHD files). Every game opens normally, If I open DEMUL, selecting them from the list! Why is only psyvar2 now opening automatically, if selected in LaunchBox, and all the other don't?

Hello again Joe, for now Sega Naomi is the ONLY platform associated to DEMUL. I looked at your settings. You have only in the section 'on associated platform' a script: -run-naomi -rom= You have no 'default command line parameter' in details section. I tried your settings, but it does not work. The issue is always the same. Just to know, do you have DEMUL in the LaunchBox/Emulators directory? Do you have the full-set Naomi games (with all variants)? Since I do not have all the Naomi game and all Naomi game variants, I am just supposing that LAUNCHBOX is not able to let DEMUL automatically find the file selected in Launchbox. Is that possible? I also did some coding with a file .bat, as testing, it seems LaunchBox could have an intrinsic limitation in passing parameters to batch files for configurations on external drives, but I am not sure since I am not a programmer. Thank you again for helping.

Hello Joe, Thank you for answering so fast. The ROMs Path was already setup inside DEMUL itself, before applying your recommendations, which unfonrtunately did not work (as you can see in the pics below). Something, I did not mentioned, is I have Launchbox on an External Drive. DEMUL is not in the Emulators Folder of Launchbox, but I think this is not a problem, since Launchbox opens it, when I choose a Naomi game, but it is the game itself, which does not open itself automatically. I still have the issue, and I do not understand what is wrong. Do you have the same problem? Could you please be so kind sharing your correctly working Naomi settings with Demul in a picture, here? Why is the idea to make a file .bat as a DEMUL BOOT, like the following, wrong? @echo off set romname=%1 "<path_to_demul>\demul.exe" -run=naomi -rom=%romname% Thank you in advance.

Hello to anyone, I started to use LaunchBox yesterday. Today, I realized I have the same problem you had in 2015-2016 (reading your threads). I open a Naomi Game from Launchbox, Demul opens up with the opened game list to choose instead of opening straight forward the game already chosen in Launchbox! I also tried to use the following commands as default parameter command of DEMUL emulator, but they did not solve the Launchbox issue: -run=naomi -rom="%romfile%" -run=naomi -rom= -run=naomi -rom=<romname> Did anyone solve this issue?... Thank you in advance for helping for helping.
