Wrong way around, the name table is the tile map, and the gen table is the patterns themselves.

The Gen table is split into Pattern and Colour tables.  There are three tables of 256 patterns for each of pattern and colour (unless you muck around with some of the screen settings ;))

Hmm i am in mode 0 .. is that why i am having trouble giving seperate colors..

Everything else is working in mode 0 i can set the top block color but the lower one ends up matching.. i used a diffrent character for it.. if my top color is a $2000 .. where is my lower one in the color table..i have tried many places..

Opps i posted my response on wrong thread.

 

I have this mode all worked out now .. 256 diffrent tiles with 32 diffrent sets of color combinations assigned to them in blocks of 8.

My mistake was thinking the it was like the zx spectrum where color is assigned to the screen.. but in this mode color is assigned to the tiles. Thanks again for the help.
