I just wanted to play SEGA GT on Dreamcast to get some fast new cars......but then this idea hit me once again!
Here's the download (binary executable + ISO):

Texture Coordinate Test
for SEGA Saturn by The Rockin'-B, www.rockin-b.de
This demo was entirely made on one evening to demonstrate that my
Saturn Game Tutorial & Demo
http://www.rockin-b.de/saturn/SaturnGameTu...ameTutorial.htm
is indeed doing a good job.
The Saturn hardware can't do texture mapping with texture coordinates. I'm just trying to do it nevertheless...
About & Controls:
You see the source and target texture (each 128x128 pixel, 16 bit) and furthermore a blue rectangle on the source texture and the coordinates of it's 4 corner points.
The target texture is just what is inside the rectangle.
The control pad buttons
X Y
A B
are assigned to the 4 points of the blue rectangle, just like you see it on the screen.
To change a point's position, select the points to move by holding down the assigned button (X Y A B) and then move them with the D-PAD.
Now how holding down one of the buttons L or R will compute the new target texture from the content inside the blue rectangle.
L - let master CPU do computation
R - let slave CPU do computation
You will notice a slight slowdown when activating target texture computation while moving points.
You can do funny things with it!
