Demul - Rom Selection?

[Biz101782]

So I have been able to set up the Demul and the commands.  Of the 8 Roms I am trying to use, 1 of them boots up from Launchbox and BigBox with no problems when selected.  The other 7 roms, when selected from launchbox they bring me to the Demul window and "Select a Rom"  window.  I can still select the rom from that window and it will run, the problem is I like to use Big Box, and if I do it this way it freezes and the Rom will not load up.  Any idea on what I am doing wrong with the other 7 Roms?  Thanks

You have several versions of the ROMs, does LB know which one to run? Otherwise it probably just open Demul and asks you to select one.

LB does not know which one to run.  How to I direct it to run certain roms?  Do I need to put something in the command line?  Thanks

You have set up Demul correctly in LaunchBox.

You mean you have not imported the roms into LaunchBox?

Anyway, you have to add the path to your roms and bioses to Demul itself as well. Open Demul > Config > Plugins and Paths > Roms and Bioses Paths > Add.

*Edit*

Seeing as your screenshot shows you want to play Sega Naomi games, these days the RetroArch Flycast core or Flycast stand-alone are better options than Demul.

demul 0.7 - V sync?

Seeking some advice:. When I turn V sync on, the roms run very slow and choppy, basically unplayable.  When I turn V sync off, the frame rate is great, but bad screen tear.  Running on a widescreen 50" TV.

Any advice on what to set the setting to or what plug ins I should set?

My desktop PC is a i7, 3060i care, 32GB ram

Thanks
