     4: 	Alpha Mission ('p3.6d' is a bad dump)

     7: Change Log
     8: ----------
     9: 
    10: AT08XX03:
    11: 
    12: [Common]
    13:  - cleaned and consolidated VIDEO_UPDATE()
    14:  - added shadows and highlights
    15: 
    16:  * A.S.O and HAL21 do a lot of palette cycling therefore
    17:    conversion to tilemaps may be disadvantageous.
    18:    Cocktail mode involves changing tile offsets and sprite
    19:    coordinates and is still unsupported.
    20: 
    21:  * Manuals show both boards have noise filters to smooth out
    22:    rings and scratches which are especially audible in HAL21.
    23: 
    24: [HAL21]
    25:  - installed NMI scheduler to prevent music trashing
    26: 
    27: [ASO]
    28:  - fixed music and sound effects being cut short
    29:  - fixed service mode(hold P1 start during ROM test)
    30:  - improved scrolling and color
    31: 
    32:  * Stage 5 boss' sky and the first half of stage 6's background
    33:    appear to have consistent color as shown in Beep! magazine:

    36:      http://qtq.hp.infoseek.co.jp/kouryaku/aso/aso3.png
    37: 
    38:    Compared to MAME these areas are blacked out under pens
    39:    0xf0-0xff. On the other hand pens 0x170-0x17f suit them
    40:    perfectly but they are never used in the first two loops.
    41:    (I played through the game and logged pen usage. Only four
    42:    color codes have blue pen15 so it's not difficult to tell.)
    43: 
    44:    There are unknown bits embedded in RGB triplets and the whole
    45:    upper half of the palette is simply unused. The fact that ASO's
    46:    color PROMs are identical in every set dismissed bad dumps but
    47:    increased the likelyhood of proprietary logic which is quite
    48:    obvious in Touchdown Fever and HAL21.
    49: 
    50: [TODO]
    51:  - find out what "really" messes up ASO's scrolling
    52:  - verify color effects in both games
