This was my first test to see the absolute maximum speed my reverse vertical screen scrolling racing game routine can run. Very early days and lots of "donkey work" to do now with multicolor mode user defined graphics (which are a nightmare for me) and sprite data(simple) to type in so I can show what the levels will look like in part 2. Then I can test how fast the routine will run with 2 or 3 car sprites being updated, collision detection for sprite/sprite and sprite/background, update to "cars passed" variable etc. If I ever finish it I will compile it with PETspeed compiler for a little bit of a speed boost but most of the heavy lifting is being done via a ROM hack SYS call which is not going to be faster when compiled.
