Hi everyone, I'm just starting to get interested in the X68000 and have some questions about the graphics hardware.

I've read through all the FAQs that I could find, and the most helpful thing was the "screen control" section in the wiki here, but I'm still confused by what seems to me to be conflicting descriptions of the X68000's capabilities on different pages.

I'm hoping that someone can help me out or point me to a better source of information.

My (very limited) understanding so far is that the machine has ...

1 Bitmapped "text" screen layer that is always 1024x1024 16-colors, and that can't be hardware-scrolled.

PLUS

1 Bitmapped "graphics" screen layer that can be set to either 256x256 65536-color OR 512x512 256-color OR 1024x1024 16-color. This screen cannot be hardware-scrolled.

PLUS

1 Tilemapped "BG" screen layer at 512x512 16-colors-per-tile or 2 Tilemapped "BG" screen layers at 256x256 16-colors-per-tile. 256 tiles are available (not sure if they're 8x8 or 16x16). These BG screens can be hardware-scrolled.

PLUS

128 16x16 16-color sprites (with memory for 256 patterns) ... I don't know the individual pixel resolution (equivalent to 256x256 or 512x512 ???).

Can anyone tell me if I am I even anyway near close to reality with this???

Do all the layers have to be set to the same out resolution???

Thanks!

Well, I guess that I was almost entirely wrong!  ::)

Looks like the information that I was looking for is "hidden" here ...
