256 Colour and 16-bit Truecolour Modes Working in the Picasso96 RadeonHD Driver

Posted by Hans de Ruiter

The 256 colour (i.e., 8-bit) and 16-bit modes are now operational. In fact, they were working yesterday, but I forgot to mention it due to suspected issues with the graphics memory of the Radeon X1300 card that I have. There is no screen shot with this log entry because the difference between the 256 colour mode and truecolour is hard to notice from a photo. Obtaining a working 256 colour mode simply required writing the colour-map to the graphics card's Look Up Table (LUT). The 16-bit mode was already operational, but the Radeon X1300 hardware issues made it appear as though there was a problem (vertical lines were visible in parts of the display).
