 Re: New discoveries on graphic CHAR command

Yes MMSZ I agree, but even to design a dedicated charset for Multicolor could not be a good solution, because with a 4*8 matrix there are definition problems. For example how to draw an "M" with only 4 horizontal pixels?

Another bad issue is the blocked charset #1 used on graphic modes. It should be easy to have set a RAM cell with the number of set to be used. And, since the HW reverse mode is not used, the characters from 128 to 255 are theoretical availables...

When I upgraded the PlusGraph, I met these problems, and bypassed them by copying the routine to the RAM in order to be free to set witch set to use (BTW O.S. can use both the sets in the same screen).

*EDIT*
I've found a way to use Charset #2 by CHAR command in graphic screen. Just set $02E4 = $D4.
...and the readability too is not so bad :)
