Summary 06683: suratk: Visible area is too small and missing background rotation
Description The visible area of Surprise Attack is 288 x 224 and it's too small since it was added to MAME 0.36b4.
See Surprise Attack_Arcade-MAME0189.png or compare with the video from Corrado Tomaselli

You can see there's much space after "INSERT COIN". In MAME the screen end up right after "INSERT COIN".
Also, the full text "Clearance point of this mission" at the end of the first mission can you only see if you set
the visible area to 320x224. That is the complete screen of the game (see Surprise Attack-Text.png).
Change line 191 in drivers\surpratk.cpp from
MCFG_SCREEN_VISIBLE_AREA(14*8, (64-14)*8-1, 2*8, 30*8-1 )
MCFG_SCREEN_VISIBLE_AREA(12*8, (64-12)*8-1, 2*8, 30*8-1 )

Also missing background rotation. Corrado Tomaselli wrote:
The background is rotating while in Mame emulator is steady.

All Konami games from that era probably should have 320x224 which was verified with some games (Bell & Whistles, Super Contra, 88 Games, Crime Fighters).
