@Jason Carr @Retro808 Yes thank you that did it! But this message came up from LB upon saving. I just hit NO and I'm back in action! Thanks for the help to get it working again! I'm currently on Mame 0.208, so if I upgrade to the latest version I would have to put the command line back in?

@Agent47 Attached is my mame optioins in LB... Maybe you can have a look. Again what is there worked fine before the update, but not so anymore

Thanks for the reply @Retro808and @Jason Carr. I am on Win 10 and reason for lack of updates is I dont have my Mame Cab hooked up to the internet. So this morning I decided to hook it up after probably atleast 6 months and update. There was a Win10 update along with the Launchbox update. I don't use Kaprasky or Riva Tuner/MSI Afterburner. I tried your suggestion @Jason Carr regarding the startup but with either setting on or off i get the same results in both launchbox and bigbox mode. SOrry but i dont know what version was before, but I believe it was above 9.2 i have no idea what is going on. when i run the games straight from mame everything works so its not mame itself causing this. WHen I run a test rom with RocketLauncher it also works fine.

My arcade box upgraded LaunchBox to 10.1 this morning and all of a sudden I get this message for all games: Invalid mode supplied: "mame". Nothing is playable anymore.... what happened??? From some googling I did, it seems to be a RocketLauncher error of some kind. I haven't updated Launchbox in probably 6+ months or so; something has obviously changed from whatever 9.x version I was on to 10.1. Anyone have any ideas where to start? It took me forever to figure out RocketLauncher with all the bezels etc, so I'm at a loss of where to even start right now, and not looking forward to trouble shooting lol
