, ügyeletes vagyok, 7:20-tól a gép előtt ülök 1 órás megszakítással.
The EP has 8+8 colors in 160x200, similar to C64.And there is another problem, most of the scrolling C64 games uses character based screen, where maximum 1000 bytes should be copied in each phase, on EP this solution is impossible, because character based screen can be scrolled by 8 pixels horizontally, and other problem is the lack of sprites, the other possibility to use pixel screen, but copying the whole screen is very slow, because 16KB data should be copied, we have one good solution, use the pixel screen, and move the starting address of the screen and fill the 1st or last column depends on onto which direction was moved in LPT, by this we can achieve quite fast horizontal scroll, but only by 4 pixels, which can be half if 2 screen is used and it's content is moved by 2 pixels.
I even have a palette setup which is very close to the C64 colors (BIAS makes it impossible to be 100% accurate)
There are smart techniques for smooth scrolling and fast sprite handling, so a C64-like port is possible.
The only problem is that the resolution of the scroll and sprite positions is 320 pixel on the C64, even if the screen resolution is only 160 pixels. This makes the movements on C64 nice and smooth - something what we can not achieve on EP.
