Beta 10 is out now with game controller support for LaunchBox.Next (finally). I took a slightly different approach than OG LaunchBox, but I believe this provides much better accessibility throughout. Basically, the controller just acts as the standard Windows mouse cursor. The buttons can still be assigned to do the same various tasks, sans for two of them: full screen (which doesn't exist and isn't planned to since .Next is already full screen when you turn off the sidebars) and top menu, which is pretty much irrelevant.
@MadK9 Any update on that issue you were having?
@kmoney I'm not sure if your issue is the same as @MadK9's. It sounds like it's not showing in the list at all for him, though I could be wrong. I haven't been able to replicate .Next not scrolling to the new game though. Does it happen every time for you?
@Retro808 That's an odd one. The only thing I can figure is some kind of darn video driver bug, but if it's freezing .Next, there may still be something I can do to get around it. The problem is figuring out where it's happening in the code. I'll at least see if I can replicate it by changing MAME.
