Summary	00033: aof2: High difficulty settng and freeze.
Description	When you select difficulty 8 in the service mode and exit back to the game, and after you select your characters and begin the fight, it displays "IRQ2 enabled, need raster drive" at the bottom and the screen goes completely black. All other difficulty levels appear to work fine however, it's just 8 which causes problems. Worked up to Mame 37b7 them from 37b8 onward the bug started. Updated by Kitsune Sniper in 0.105: Previously the game froze with the 'IRQ2 enabled, need raster drive' error being displayed in the screen. In 0.105, the error still happens but the text is no longer displayed. Also, in previous builds I tested a while back, the freeze seemingly appeared once the screen faded in completely, but now it doesn't even do that. It freezes in the middle of the fade-in.
