Mario Bros. (Tengen)/Version Differences

Copyright Screen
Trademarks were added after both "Fighterfly", "Mario", "Luigi", "Shellcreeper", "Sidestepper", "Slipice" and "Nintendo", a registered trademark was added after "Mario Bros." and the Tengen logo shifted closer. Also, Version 1.0's copyright screen is displayed for just two seconds; this was extended for 1.1 to eight seconds, although pressing Start after four seconds will take you to the title screen.
