Title: Mode 1 half width characters, 80 columns
Post by: kolleykibber on 20:41, 12 December 23

I remember in Commstar HoneyView that they use mode 0 with half width characters to get the 8 colours for Viewdata's 40x24 screen.

I was wondering if anything like this has been done for Mode 1 so as to get 80 characters and 4 colours?

Hello !

Yes that's what Antoine P. used to use in his tools back in mid-90s.

For an example, click here to see some screenshots of one of his tool: cheese cruncher 1.1 © _public_domain_ (1994) (cpc-power.com) (https://www.cpc-power.com/index.php?page=detail&num=9729)

i also remember a post from @ZbyniuR from 2016 somewhere here in the forum? where he showed a sample basic code doing that in mode 1 ( Lemmings walking ), but the principle is a half width character in mode 1, so 80 characters in a line with just some pokes... i also used it for a program... have to look for it

Wow. Thank you. That stuff is great. I was thinking it would have to be done in machine code writing each pixel to the screen.
