How do I show sprites in the border on C64?
I think the “init VIC” code at 0xC148 mainly sets up sprites in the border for the sprite scroller (It’s connected to disabling the border.) But the sprites have to be there otherwise the timing of VIC/raster lines is different and the whole thing does not work. And you want to be sprites there anyway :-)– Peter KoflerSep 28 ’09 at 9:25
How many sprites are there on the Spectrum Next?
The Spectrum Next has a hardware sprite system with the following characteristics: Total of 128 sprites Display surface is 320×256 overlapping the ULA screen by 32 pixels on each side Minimum of 100 sprites per scanline* Choice of 512 colours for each pixel Site of each sprite is 16×16 pixels but sprites can be magnified 2x,…
How many patterns can a 4 bit sprite identify?
N6, despite the name, is the least significant bit. This 7-bit pattern number can identify 128 patterns in the 16k pattern memory, each of which are 128 bytes in size. The full 7-bits are therefore used for 4-bit sprites. For 8-bit sprites, N6=0 always. The remaining 6 bits can identify 64 patterns, each of which is 256 bytes in size.
How many pixels does it take to qualify a sprite?
The sprite hardware is able to plot one pixel cycle and uses one cycle to qualify each sprite. Since the number of cycles there are in a scanline varies with video timing (HDMI, VGA), the number of pixels that can be plotted also varies but the minimum will be 1600 pixels per line including overhead cycles needed to qualify 100 sprites.
How are sprites controlled on a Commodore 64?
Sprites are controlled by a separate picture-maker in the Commodore 64. This picture maker handles the video display. It does all the hard work of creating and” keeping track of characters and graphics, creating colors, and moving around. This display circuit has 46 different “ON/OFF” locations which act like
How do you make animation in Commodore 64?
A way was also shown to POKE character codes in specific screen memory locations. This would then place the appropriate characters di- rectly on the screen in the right spot. Creating animation in both these cases requires a lot of work because objects must be created from existing graphic symbols.
How do you draw a grid in Commodore 64?
Number down the left side of the grid 1-21 for each row. Write the word DATA at the end of each row. Now fill in the grid with any design or use the balloon that we have. It’s easiest to outline the shape first and then go back and fill in the grid.
