Hi!
I used own VDC modes and it needs to customize C128 Editor default 80x25 dimensions. I found not any note where can be Editor code in ROM stored. I don't want to write own Editor - need not to reinvent the wheel. Better is also first to see how it is created and then apply own changes.
Thank you for your support. Miro

C000-CFFFF, however the VDC init routines are E000+ and part of the KERNAL modifying it for things that are not 80x25 is not trivial, if you want to go smaller it should not be that hard and honestly just use the Window Command to get it, if you want to larger in the X or Y you will run into pain, see my post in VDC about 80x50..
Computes mapping the C128 will be invaluable to you.

I know that smaller area can use WINDOW command, but I used 100 characters wide mode.
I try to find it, maybe it will be possible.

for 100 characters wide but the same number of lines, probably do able, I don't think people will care if the tab stops don't go into the extra 20..

I used 50 lines non-interlaced with help of Torsten Kracke (aka tokra) but yet it flickers for VSync, so it needs adjusting.
This is reason why I mentioned not height.

How does the 50lines non-interlace work?

Yet is it possible to display it correctly in Z64K (Z64K problem emulates not, even emulates incorrectly 100x50 with attributes) - no flickering.
Two modes - 80x50 and 100x50.
Also on C1901 monitor without flickering by adjusting VSync, but C1084 and others have not available VSync correction, to it flickers - but not characters, flickers whole screen.
It needs to adjust VSync to lower value, so also it will be not 50 lines, it needs less lines, but I want to use as many as possible.
But without Editor for 100x50 it is for direct mode useless and 80x50 allows use only 25 lines even when is 50 displayed - it is possible use whole screen in both modes only by direct write to VDC-RAM.

Can you list the register changes you made? I would like to try this...

I couldn't get this to display at all  Both my monitors just said out of range, with and without the linedoubler. That IS a shame, I guess I don't get to play with it. |
