*Switchblade : the GX4000 cartridge version is displaying extra features such as large vertical ditherings in a lot of Red shades (sky) or PLUS Hardwired sprites "patches" as extra coloured tiles...this is more than enough to get a properly coloured feeling.
Some Speccy port "done right" may also use Mode0 instead of Mode1... hence being graphically fully CPC (yet tiles or sprites are still compairablein dimensions).
The result may vary from awfull (the code is not optimised enough for CPC) to great (alles ist richtig...).
