José Pereira #1 Posted June 22, 2011 GTIA 16shades controls all Luminances in Backgr.register and there isn't PF3 (and any other PF used). Probably silly but PF3 is part or not of GR.7/15? Quote Share this post Link to post Share on other sites
Synthpopalooza #2 Posted June 22, 2011 GTIA 16shades controls all Luminances in Backgr.register and there isn't PF3 (and any other PF used). Probably silly but PF3 is part or not of GR.7/15? There is no PF3 in Graphics 7/15, only PF0-PF2 and COLBK PF3 is used in Graphics 12/13 (Antic 4/5) which is the text mode equivalent of 7/15. Inverse characters which use bit pair "11" in their character grid replace PF2 with PF3. Apart from Graphics 10 and any other modes derived from it, no other graphics mode makes use of PF3.
