Ok I can get the game working now if I start the game and hit tab and change the slot to sgm and reset. How do I get this to launch without doing this all the time? Create a ini? If so what would I put. What would be the command-line?
Thanks
EDIT: mame coleco -cart smg asteroid
works
Now what would I put as a ini so the games launch? I tried making a coleco ini and inside putting -cart smg but that doesn't work.
