why not 39 column mode ?
if hiding 1 row is enough for doing vertical scrolling why do we have 38 column mode for horizontal scrollin, why not 39 ?
(and besides anyone can give me a simple random generator ? register readouts doesnt count) |

never mind, i think its a Vice glitch - Ive mucked around with the code a bit, and now it shows a solid black area on the bottom (26th) row instead of chars....
Anyhoo, on with the show.

@Style: Well you CAN get 26 char lines, but only with 25 bad lines. The 26th line is just a duplicate of the 25th, i.e. no new badline. |

The scroller in my part of Panta Rhei also uses the 26th char row... just because I could. ;) But as I said before, it's no new badline condition. |

Quote: I'm just guessing here, but I think it's because they didn't want the screen to be off center. When shrinking to 24 lines, you lose 4 lines at the top, and 4 at the bottom, keeping the screen centered. To get the same effect with 39 columns, they'd have to remove 4 pixels on each side. This would be really hard to do, as that would change the vic timing by half a CPU cycle. They could have shrunk it by 8 pixels on either the left or the right side, but that would leave the screen off center. Thus they went with 8 pixels on each side, leaving the screen centered.
Ehr... This is exactly what I was trying to say... :) |

why would adding 4 pixels on each side be any more difficult than adding 7 on one side and 9 on the other? |

It is a new badline condition, just no fetch of new memory ;-) |
