Hi there-
I'm running into an error I can't seem to resolve. For a little context, I'm on Windows 10 running LaunchBox 13.24 and I've got my ROMs sitting on an external HD in their own folders (e.g. R:\Arcade\Sega Genesis\roms) outside of the LaunchBox directory (which is on the same external HD, R:\Arcade\LaunchBox), and have imported all of my ROMs in the same way using Tools>Import>ROM Files>Single Platform. Arcade ROMs are running on MAME, and console ROMs are running on RetroArch.
Here's my problem: I click the "More Options" (3 dots) menu below a ROM (for example in the Super Nintendo Entertainment System platform), then click "Configure", and I receive an "An error occurred while trying to launch the game: Object reference not set to an instance of an object." error. I've tried Tools>Download>Force Update Games Database Metadata to no avail. I can play the ROMs just fine, so this isn't a critical error, just something I stumbled upon and found strange considering everything else works as expected, as far as I can tell.
Something else I don't understand is that for certain platforms, e.g. Sega Genesis, clicking the 3 dots menu on a ROM only gives the option to "Delete" and doesn't have the "Configure" option at all.
TIA to anyone who can shed any light on this.
