anti badline trick
hello, i did the anti badline trick to have open sideborders, grafix and 7 sprites and it works just nice..
simply increment $d011 to avoid badlines witch also repeats or streching charline 7..
my question is. is it posible to do the same trick but instead of streching charline 7, streching charline 6
is it posible anyway to repeat the 6 or 5 or 4 charline?
thanks a lot for reading this topic

iirc you can only stretch the first and last (or only one of them?) line of a char row. |

speculation: to have different gfx on other lines you need to switch video banks. If you don't switch video-bank you will have the same gfx on every line. Maybe I'm wrong. It's long time ago since I played with do11 tricks. |

not only videobank, but also $d018 helps =) |

And if dd00+d018 isn't enough you can double the amount of gfx lines by using Xbows trick from Krestage 1 (I think) where he turned the extended bg-color mode on/off, bringing the total amount of lines up to 56. Only works in single color mode though. |

one thing that i found very smart when figuring it out (probably long after others did =P) was that you can store the same value into d018 and dd00, ie in your rastercode its a simple
lda #something
sta $d018
sta $dd00
examining which bits in do18 and dd00 effectivly do something highly recommended ... =)
@oswald: you already answered his question in your first post, so why shouldnt we throw in some other thoughts after YOU came up with fpp? =D |

ok I realized what's mcd's goal is.
mcd, use sprite fpp, that will give you 256 different any place any times gfx lines. and you can make it even more than 256... |
