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.
