this is an xy problem whatever you can solve with 7 pixel high char rows should be solvable with 8 line high ones |

Quoting Oswaldthis is an xy problem whatever you can solve with 7 pixel high char rows should be solvable with 8 line high ones I thought XY problem as well, but for other reasons. =)
Digger: As in really, why is a scattered memory layout such a big problem that it invalidates the entire technique for your purposes? |

You could possibly do something ungodly with alternating 6 line rows with 8 line rows, so RC would go 01234501234567, but do a FLI fetch on the 8th line to fetch from a second char screen.
In char mode you'd be alternating between two screens, and using the first 14ish rows of each screen. You'd have to use a couple of charsets, where the second one is rotated down a line, and also duplicates line 7 into line 0 for use on line 7 of the even char rows.
(so, you only move on to the next row address every second char row, but it's a lot closer to what you're asking for than never advancing) |
