[Microbee] Which mode is 160x48?

Post by Fabrizio »

Hi,

Which mode should I use for the MicroBee built-int 160x48 graphics mode, which supports UDG?
The documentation at https://github.com/z88dk/z88dk/wiki/Platform---Microbee
only mentions this resolution but no corresponding mode is given.

I see text modes 0,1,2. Is this mode 3? or one of the text modes? Which one?

Support for UDG on higher resolutions would also be nice (if technically possible).

> The MicroBee port supports three graphics variants. Low-resolution (up-to 160x48) is built in by default. This form cooperates with the generic console and allows the use of custom fonts and UDGs.

Lores graphics in z88dk means that "block graphics" are available these typically divide a character into 2x2 or 3x2 pixels.

So, mode 0 which is 80x24 provides a graphics resolution of 160x48. Mode 1 which is 64x16 provides a graphics resolution of 128x32. Mode 2 which is 40x25 provides a resolution of 80x50.

Thanks for the reply!
Do the other higher resolution graphics modes currently support Z88DK software sprites?
Are these graphics modes only meant for special extra hardware or do they target standard Microbee models?

I have just read that the high resolution modes are based on redefined characters (PCG) and that not all models had the same number of available PCGs.

Shouldn't UDG graphics in Z88DK be possible by just doing a mapping to PCGs?

https://en.m.wikipedia.org/wiki/MicroBee
look at the section referring to the Premuim version (1985)

The SW Sprites are supported.
