Running BigBox 11.12 I'll launch a game using MAME (.228 if that matters) and get the startup screen, which is great. However, no matter how long I set the startup screen time for, once it exits, it still takes another 4 seconds to actually launch MAME. During that time, Bigbox comes back and starts playing the video of the game like the launch failed. Of course, the more impatient people that use the cabinet will launch the game again so now we have two copies running. I've tried changing the startup time in the emulator and that doesn't seem to change things. What else can I look at to fix this, or is it a bug?
