  1. 2021.05.16 A2 Turbo card scroll test on Game

Dear Friends and cutomers,

 

Below is the speed test screen in the scroll game.
In APPLE II, it is  the best scrolling screen on the game.
(The sound was not recorded, but there is sound as well)

https://youtu.be/5UQ8SOpKwig


On the Demo, It shows the screens at 7.16Mhz, 3.58Mhz and 1Mhz respectively.
If you compare, you can see how much difference there is.

if you play the game, there is a sound of shooting a gun, and the sound of dropping a bomb and being detonated.
But, I'm not sure what is the purpose on game.
I guess that It doesn't seem to be made properly due to speed problems.

If made for accelerator cards, a much better screen and smoother look of enemies and friendly planes and  the blast planes.

If I think to make similar as this, set the CPU to 3.58Mhz and reduce the scrolling speed a bit, and handle other things more, 
It woulbe be much better game appearance would have been possible. Of course, if the speed is based on 7.16Mhz, it will be possible to drive more spare CPU power.

If I try to make a game later,
I would like to make a game that supports a merking board or a music card on such a scrolling screen.
It is almost impossible before the accelerator.

With A2 Turbo, programming with Apple 2 will be more fun. 

Thanks
Ian Kim
