Can't launch Naomi game

[Megahurtz]

I'm trying to launch Street Fighter Zero 3 Upper and am completely at a loss as to why it isn't working.  I have an emulator entry set to load retroarch.exe with a switch to specify the core to use.  I have some other games that load and work properly using this method.

Here is where I am really confused.  If I go to the command line and manually enter the command Launch Box should be using, it works fine!

retroarch.exe -L "cores\flycast_libretro.dll" "c:\emulators\retroarch\roms\dreamcast\sfz3ugd.zip"

I can type that in and it loads right up in Retroarch with the correct core.  So what is going on with Launch Box where it displays the loading screen and then just dumps me back to LB?

Ok, I figured it out ?

What tipped me off was when I was in the desktop LB interface, if I right-clicked on Zero 3 Upper, it had an option to Launch with Retroarch which then expanded to another submenu that said reicast (the old DC/Naomi/AW core I was using).

In the manage emulators menu, I edited my Retroarch Naomi listing.  Like I said, I was using a command line switch to force a core load, but somewhere something in LB was still looking for reicast.  The answer was in the associated platforms tab.  Sega Naomi was still set for reicast_libretro even though I had deleted that core from my RA install.  I clicked that and found flycast in the dropdown list.  Picked that, hit ok, and tried loading up the game.  Worked perfectly!
