Changes
== Advanced testing ==
* Only horizontal timing of the CRTC is affected.In order to get a stable image , you need to program register 0 at 95 (96 characters line) and Register 2 at 61 (centering for 40 characters default)* Pixels pitch is 66,.7% of their original pitch.Theses pictures show this fact (320*200 320×200 mode 1 pixels with black border)

* This speed improvement is 16.66667%.This has been tested with this simple program :
10 i = 0 20 after 500 goto 100 25 cls 30 i = i +1 40 ? i 50 goto 30 100 end
(Theses results can be subject to discussion as we are not sure interrupts timing is not affected)
