|  Software Sprites on the Plus/4 (a question)?
One of the things I have thought about is to "shadow" bitmapped dots on
top of areas of the screen where a sprite bit is turned on, those
overlapping the sprite with bitmapped dots with 100% accuracy. The
bitmapped screen is then saved, and the bitmapped version of the sprite is
then LOADable on the Plus/4 (or C-128).
The sprite doesn't need to move, at least not in this case, because it is
for a title screen for an adventure game (a port of my game "Mystic
Castle" on over to the Plus/4...I figured out how to do Windows on the
Plus/4 by using ESC+T and ESC+B...took me several years to realize that
the Plus/4 *can* do windows, it just lacks a Window command).
The exact sprite I want to emulate with a bitmapped copy is:

The Mystic Castle title screen sprite is simply the "Mystic" graphic above
the "For the Commodore 64" yellow marquee.

You mean the title graphics on the top? Why would that need to be a sprite? A software sprite is definitely doable, and there are even some existing utilities that do just that, but in your case all you need is a custom (or redefined) font. Very simple to do, TONS of basic games here on the site do it.

All he really needs is a shadow of the ROM font and to replace the unused characters with the graphics for the logo. It'd be a bit of a tight fit because the game is using lower case and inverted characters so there aren't going to be many free chars to "borrow" space from...

I said redefine the font, you said replace the characters. Aren't those exactly the same?  (I think we do mean the same thing.)

We do, but i was expanding on the answer and pointing out how few characters were available to replace. =-)
