good question :)
i'd like to try toggle :) i dont think it needs a 2^n
screen resolution :) you can get the available bitmap
depths using an API.. we'll just have to check if it is
12 rather than 16 :)
for compatibility purposes, they may use 16bit windows
internally and adjust to 12 bit at runtime:
5:6:5 --> 4:4:4
r >> 1
g >> 2
b >> 1
a lookup table could easily be put in rom for this purpose
- they units are not flashable :) it'll be nasty with pixel
boundaries since 12 bit = 1.5 bytes per pixel :)
will probably give the desired effect.. however, a lower
bit count on the green might give it a red/blue tone.. i
would like to see it personally and do some tests myself
