Multicolor text mode 4x8

Hi!

I was read on the wikipedia, some information about text mode Commodore C64 - 4x8 multicolor:

| Text mode: 40×25 characters; 256 user-defined chars (8×8 pixels, or 4×8 in multicolor mode); 4-bit color RAM defines foreground color.

But as an example, show only the standard text screenshot.

Somebody can explain to me what is it this in text mode, as it turns on and preferably with an example.

I would be glad if you bring in a sample screenshot.

Many thanks in advance.

Hehe yes, ofcourse. I meant the independant choice per 8x8 block. $d021,22,23 would account for the entire image (unless splits are used)

Quote: I have an idea for a gfx mode using the char method (in combination with sprites)

Limitation ofcourse is that for Hires, only the first 8 colors can be used (same for Multicolor. 8-15 is mapped onto 0-7) hence careful selection of the two main multicolors are required ($d022-$d023)

This is why you dont see any hires parallax (as in turrican/turrican2/phobia/mayhem in monsterland etc) or any hires combo using any hires color (8-15)


since when are colors 8-15 called hires ? :)

Hehe i certainly worded that incorrectly. I meant that colors 8-15 dont appear in a 8x8 hires block if using the mcol char mode (unless $d021/22/23 is used)

Isn't it an oxymoron stating:

XXX doesen't appear in a 8x8 "Hi-Res" block if you use "Multicollor"?




I know... I'm just out for some shit and giggles 8-D

Multicolor Char mode i meant (Which can comprise of hires and mcol blocks) instead of multicolor.

The mode has some potential. Combined with multicolor underlay and $d021/22/23/25/26 splits I will see what i can come up with
