Some more debugger fixes.
Added AM_WRITEONLY as a shortcut for AM_WRITE(MWAx_RAM). Cleaned up Kangaroo driver: * documented MB8841 (needs to be decapped to get code) * proper video timing * full memory maps * simplified and more accurate video logic

Convert the color PROMs into a more useable format.
|
||||
|
||||
Kangaroo doesn't have color PROMs, the playfield data is directly converted
|
||||
into colors: 1 bit per gun, therefore only 8 possible colors, but there is
|
||||
also a global mask register which controls intensities of the three guns,
|
||||
separately for foreground and background. The fourth bit in the video RAM
|
||||
data disables this mask, making the color display at full intensity
|
||||
regardless of the mask value.
|
||||
Actually the mask doesn't directly control intensity. The guns are rapidly
|
||||
turned on and off at a subpixel rate, relying on the monitor to blend the
|
||||
colors into a more or less uniform half intensity color.
|
||||
|
||||
We use three groups of 8 pens: the first is fixed and contains the 8
|
||||
possible colors; the other two are dynamically modified when the mask
|
||||
register is written to, one is for the background, the other for sprites.
