NO!
that fails mysterious!
the entire Screen is shifted one Position.
it started not at the leftmost Position!
and the Color block of eight is moved too
see Picture
Try to go thru things in debugger.
The thing with using 0x4000 as write address gotta work, coz that high byte much smells like it was the result of an AND 0x3F OR 0x40 operation.
And the colorblock shifted because colorRAM is not onscreen like C64 ZX, but part of the char itself.
To get color text you need to go screen 2 and then render it bitmap style.
it really fails.If I activate the and and or lines, it works, otherwise not.
I think it´s better to code it right, elsewhere I spend a lot of time later if it Fails again
