it works exactly the same, except you need cycle exact timing. (that said, it doesnt really work terribly well with $d011 ... try $d021 first to get the idea, and to get the timing right). |

This one simply switches the border color. (Try hitting RESTORE repeatedly. :)) Making a graphics/text split gets more involved. Since you can't make a split in a middle of a badline, you'll have to abort (yes, begin then abort) the badlines. Also, the modes won't work the way you probably expect since the VIC won't do any C-accesses.

uhm. wouldn't a horizontal be much easier than vertical?
becauase, afaik:
left to right == horizontal
top to bottom == vertical.
...or I just misunderstand the question..

Yeah, left to right == horizontal, but if you want left and right to be different (i.e. split), it's vertical ;-) |

A vertical split on $d011..
I doubt you can change graphic-mode from text to bitmap , but you will explore some nice and strange effects

Here goes a little experiment. Assemble with ACME and make sure you write something on the first charrow before running (so you can see the problem caused by lack of C-accesses). Be warned that it will take a lot more effort before you can display "proper" graphics/text.

..so i say what most others seem to be trying say, only being hardly understandable.. :)
There is no easy trick to split the screen vertically between gfx and text. However, it may still be possible, depending more precisely on your interpretation of "gfx" and "text". Do you want multicolor bitmap gfx, or is it ok with 3 colors + background? Maybe we're talking gfx in hires!? And the text, is it ok with a 7 pixels high font? Does it have to be text on a char-screen, or can it be text on bitmap?
..need more info to solve the problem. |

i still recommend watching a few of the demos which demonstrate this :) in most of them you can also clearly see the problems connected to it (eg the fli-bug alike mess you almost certainly get somewhere across the screen) |

After all, has seen many demos (from the old days) =), which raster lines divided up in many different colors from left to right.
These are split up, some ideas how it is done? |

color splits are a lot easier to achive than text/gfx :) the stuff seen in really old demos (with say 4 or 5 splits) doesnt even need precise timing, since all you do is covering the screen with a multicolor pattern and do rasterbars in d02x. and the "40 splits" stuff is just...fli =) |

If all you want is to have regular gfx on one side of the screen and text on the other, the easiest way would probably be to simply have a picture which uses only half the screen and then plot the text into the blank side of the bitmap. It would not be hardcore coder pr0n but it will work and it will take no timing at all for the display routine, as there will be no display routine to worry about at all.
All you need is to understand how the bitmap works and is setup in order to be able to put the text wherever you want it. You probably need to setup screen and color ram for the text area as well.
In order to to a regular horizontal text scroller on one part of the screen and you want to use $d016 for softscroll, you need pretty precise timing to set $d016 accordingly between the moving part of the screen (the text) and then change $d016 back when the rasterbeam hits the picture part, and then do the same over and over for every line your chars are displayed. Also you need a routine to plot the letters on the screen from the charset, as you are working in bitmap mode.

what about, filling sprites on the side of the image of text.
should be the easiest way =) |

Using sprites is surely one way to go, but i still don't really get what you want to do. You talk about splitting between graphics and text, and then you show us some demos with raster splits. That's something completely different, really <:). |

what about converting the gfx to 3col, leaving the first $0200 bytes free for a regular 1x1-charset and then showing it on screen... switch on mc in $d016 and use $d800&0x07 you get singlecolor for the charset. using some fine rasterroutine behind that for the mc-colors ($d022/23) gives you a pretty colorful logo... wisely used ;)
or take a look at crest light... vision moved the logo up and down, plotted huge balls on the screen and had even an upscroller in 1x2 size.. killer back then. |

yes it is true =)
thought it was the same thing splitting text and graphics.
if there was a way similar like use D012 to splitt from top to bottom
understand there are 2 different things
any idea, how to splitt raster like in the demo's |

No need to install it, just type "ACME <name_of_source>" and you get a compiled prg file. Also, it works like a charm on 64-bit XP, so I see no reason why that would not be the case with 32-bit XP. |

You might want to add ACME to your PATH (this is not absolutely necessary, but it will make life easier :)). Let's say you unpacked the assembler in C:\Acme. Right click on My Computer and select Properties. Go to the advanced tab and click Environment Variables. In the "System variables" listbox, select "Path" and click Edit. Now, in Variable value, at the end of the string (make sure you don't delete anything you might have here), add ";C:\Path" (excluding the quotes).
If you already have a DOS shell opened, close it and open it again (so the changes can take effect). Now go to the directory where you source code is. Once there (assuming the source code is named Exmaple.asm) type "acme example.asm", and that's it. The resulting filename is the one you give in the !to directive (in the source code).
