I created an editor with copy&paste, draw tools, pattern fill, undo/redo, export/import... for Blake's7. It is written in C# and intended for my OASIS engine, and also quick and dirty code for my use only, but I could share if someone is interested.

Re: Sprites for your games

yes !! I played with the sprite demo D.tap and i find it is smooth and fast. It might slow down a little bit when the cleaning of sprite's former location is added but it is ok because there seems to have margin. Good starting point. Thank you JBé 8) the most difficult remains : the handling of the...

Re: set color and paper

I don't think the "inc writeink+1" is correct, because if the value was 255 it will not increment the high byte value, but instead you could do that: ldx #1 suite (...) lda inkcolor writeink sta $1234,x Also by starting at 200, you are accessing the screen address array off by one (it goes from 0 t...

Re: set color and paper

If you search in OSDK\lib, you will find a "library.ndx" file, which contains the list of all supported routines, including paper and ink: -graphics.s (...) _paper _ink (...) from that you can see that paper and ink are in "graphics.s" which is at the same location: _paper ldx #1 ;Get one parm jsr ...
