You sir are indeed a legend! This has led me down the correct route (I believe). Thank you sooooooo much!!!

I am using the most recent Mame download (0.225) from the site and this rom set.

Ok, so I have dabbled in Mame in the past, but I am now attempting to make a dedicated machine. I have a PC with Mame/Launchbox/and a rom set. I have installed everything and loaded the romset into Launchbox. I Created my INI, set to rom folder. I still have an issue when launching arcade games, that only 2% or so work. almost every game flashes mame on the screen for a split second when launching before sending me back to launchbox.... any ideas?
