Updated T65 to latest version by Gyurco (from MiST)
Added loading of custom palettes (*.a2p)
Included several example palettes
Added readme description of shortcuts
Explanation: the Apple II hardware was originally a fully black & white machine, which created color by NTSC artifacting on a television. These colors depend heavily on the settings of the TV ("knobs" e.g. brightness, chroma, etc).
Later on in the Apple II life additional hardware was added to create color, but these also vary in the choice of exact RGB colors... even by Apple themselves (Apple IIgs and LCD hardware emulation). Other variations include PAL modes, modern expansion cards for VGA output, etc.
The ability to load palettes allows users to define their own settings (using e.g. colodore.com to select "knob" values); thus removing the need to replicate complex NTSC hardware (or the other options) in the FPGA.
