Hello - please forgive me, i'm new to LaunchBox. (previous Hyperspin user...)
I've updated my ROM set to .178 (clrmamepro) and I'm uses MAME64.EXE .178 to match (MAMEDEV version - no custom compiles). I've got LEDBlinky setup too.
My 'test' ROM is Metal Slug X (mslugx) - Everything runs fine when I start MAME by itself / from the command line. When I launch it from LaunchBox (regular or big box mode), MAME gets to 100% "loading rom", then hangs for a second or two, then crashes.
I've got LaunchBox successfully launching NES games with Nestopia and Wii games with Dolphin.
I'm at a bit of a loss as to whats going on here - but it feels like something the way LaunchBox is starting the emulator is causing it to crash.
Any ideas?
