Any chance for an update? I'm running LaunchBox 13.0 and it's not showing up in my Tools menu. It's not blocked by Windows or anything, it just doesn't show up at all. Other plugins are showing up - this is the only one that doesn't. This plugin is exactly what I'm looking for to help get MAME system roms working quickly instead of individually editing them. Not sure why bulk command line editing isn't in Launchbox Proper, but until then, I'd love to get your tool working! Thanks!
