@JoeViking245 After getting the new version I deleted all my associated platforms attached to Mame. I imported the Casio Loopy software list and didn't have a associated platform built with any command line parameters. I am using the latest beta version of Launchbox so maybe that could be related? Besides that I also use exodos, exoWin3x, and the bulk command line editor plugins. I wouldn't think any of those could be causing issues as most of them don't touch the mame emulator stuff at all but I thought I should let ya know.
