I’ve found a bug in the “Analog controls” submenu in MAME2016. This menu is the one where you set the analog controls sensitivity, autocenter and control reverse parameters for systems which uses paddle devices or similar controls (such as atari 2600 which has paddle controllers to some games). When you start scrolling the cursor inside this submenu, it crashes the emulator.
Here’s the LOG file reporting the crash while navigating through the “Analog Controls” OSD submenu in MAME2016:

So I ask you developers to take a look at this log file to see if it’s something that could be fixed. I really hope so. 
Thanks!
