I've discovered two MAMEUI bugs that didn't exist in previous versions (they don't exist in .145 u7)
1. Bonanza Bros. (bnzabros) When the rom is loaded the SEGA System 24 Screen & a "Now Loading" Screen appear. Then the screen goes black. This makes the game unplayable.
2. Night Driver (nitedrvr) Every time the rom is a loaded a random set of characters appears on the screen. They never disappear. (See Screenshot)
