|
Changes:
|
|
18/01/03
|
|
MMIO is no longer used, sidestepping cache issues on EPIA-800
|
|
TV-Out modes are now better supported - this should be the end
|
|
of the magenta stripes :)
|
|
Brightness/Contrast controls disabled for the time being - they were
|
|
seriously degrading picture quality, especially with TV-Out.
|
|
|
|
To Do:
|
|
Implement Hue/Saturation controls
|
|
Support / Test multiple frames
|
|
Test colour-key code more extensively
