    It is not so difficult, but you may run into timing problems as you have twice as many accesses to the HUB.

    And remember also that "Text" works in 2-color mode only!

    Checkout my Blackjack game here:

    It shows bitmaps and text on either XGA·(VGA 1024x768) or TV...

    Ah, but that's close to cheating smile.gif
    Of course you can bent any address in a tile to a corresponding piece of bitmap!

    Sorry, I thought of a true overlay, but just arranging the tile addrresses is most likely powerful enough.
    Also, I was confusing above, saying 2-color mode. The ROM characters need also 4-color mode, but you have to carefully chose the coloring! This would have been the problem with a true overlay concept...
