Summary	06155: adam, a2600, c128, c64, sms, sms1, nes, snes, snespal, vic1001: Cannot select multiple inputs in some MESS sets
Description	When defining controls for the sets included, you cannot pick multiple inputs for the same control. i.e.: You cannot pick Kbd 1 _or_ Joy 1 Button 7 for the start control. When you enter a control the second time, the new control overrides the choice, instead of appending the choice with an "or." This occurs at least in the MESS sets above. It may occur in more; I only tested machines I know you can hook up a joystick. The expected behavior is that the interface will keep appending controls with an "or" statement until you press "delete" and start over. Some sets work, such as aes. I am unsure of the regression version as this is my first time trying out MESS.
Steps To Reproduce	Launch game, attempt to define multiple controls in the TAB menu. May need to press "scroll lock" to activate the UI (e.g.: in c64).

No.12441 Zaghadka Tester Mar 8, 2016, 09:02	Seems to affect clones of these sets as well.
No.12445 NekoEd Senior Tester Mar 8, 2016, 17:41	Altered report to remove driver as multiple drivers are referenced.
No.12447 Tafoid Administrator Mar 8, 2016, 19:25	Looks to be a limitation of those devices which are obtained/used via the slot functions. You can tell if a driver has this by examining -listslots output for any type of controller. Anyway, I confirmed in a few instances listed above.
