Error When Clicking "Configure" Under "More Options" Menu on a ROM

[DenjinTV]

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.

The "problem" is, Configure shouldn't appear there.   

That is (I'm pretty sure) just for MS-DOS/DOSBox games.  Edit the SNES game and look in the Launching section.  Is there something listed next to Configuration Application Path:?  Is whatever's in there, part of the game? My shoot-from-the-hip guess is, No. Remove it and click OK to save and close.

So, I don't know why that Configure option was showing up under some platforms in the first place - but I restarted LaunchBox before checking back here again and that seems to have resolved the issue. The option no longer appears, and there's nothing in the Configure Application Path (but maybe there was before the restart - who knows). Maybe wires get crossed after the initial imports and before a restart, not really sure, but something wonky was definitely going on. Either way this is resolved.

Thanks for the info! 😄
