DING

So I tried Mameui and was able to see the error. "Unknown System 'mario-2'. Then it tells me a list of the closest matching roms and they're always the same overall game. If I am right about the source of the problem, is there a place we can look to see where they are at so we dont waste hours and hours guessing? Did I just miss it?

I'm pretty new so this may be a dumb question. I downloaded a full mame romset and then proceeded to update the roms all the way through to 0196. After that, when I try to load most of the roms, I get an error in a mame command prompt that flashes too fast for me to read but I'm able to make out what looks like a list of related files. I'm able to load all of these individually through mame itself and I remember reading a post from a couple years ago having something to do with Launchbox's romset being always a bit behind mame proper. I'm getting the feeling I may have updated too far. I have my directories set right, I'm using the corresponding version of mame, and beyond the update, there's been really no changes made to my software that caused it to stop functioning. My question is, if I'm right in thinking that is the problem, what is the most current romset version Launchbox is compatible with?
