Hi kedhrin, what ROM file have you specified in LaunchBox for the game? If btimem is the command that works, you'll need to change the ROM file in LaunchBox to be the btimem file instead of the btime file.
That said, if nothing is working, then it sounds like there's something else going on. Hard to poinpoint that though without a deeper look at your setup. Feel free to screenshot us your configuration so we can review.
