RetroTINK-4K Custom Banner Instructions

 

Banner images should be saved as 320 x 128 x 24 bit .BMP bitmap files. The color R = 255, B = 255, G = 0 (full magenta) is interpreted as a chroma key. Any pixels chroma keyed will be transparent in the OSD.

 

Because of limited FPGA BRAM resources, the color depth of the banner range is reduced for actual display. Of the original 24-bit RGB image, the Red and Green channels preserve the 4 most significant bits while the Blue channel preserves the 3 most significant bits.

 

The file 'default.bmp' will be loaded on power up if the profile does not have another file specified.
