![]() ![]() A small introduction into graphics: Hires graphic with the C64 at cbmhardware.Again, color is a limiting factor and only 1 color can be used in a High Resolution sprite. The color data for each 8 x 8 character location is taken from corresponding screen memory: the higher nibble controls the set pixel (foreground) color, and the lower nibble determines the cleared pixel (background) color.įor sprites (which are not limited to the main display area), a High Resolution image can be 24 (horizontal) x 21 (vertical) pixels although aligned sprites can make a larger image. Software control for switching between 6581 or 8580. Added: Chameleon support for two emulated sid chips. And will then ask you to center Switch 1 to allow for software control of the sid chips. Although the palette of 16 colours can be used in a full screen image, for each 8 x 8 pixel character location, only 2 colors can be used 1 for the background and 1 for the foreground. Software control for switching beween 6581 or 8580. One limiting factor of High Resolution on a C64 is that of colour density. The result is a program which can load and execute C64 machine code programs which produce music and sound. This is comparable, although not identical, to the Color Graphics Adapter ( CGA) standard introduced by IBM in 1981. Sidplay is a music player that emulates various components from a Commodore 64 (C64) computer. High Resolution can be applied to images made from characters, bitmaps and/or sprites.Ĭharacters and Bitmaps įor characters and bitmaps (which are limited to the background area), a High Resolution image can be a maximum size of 320 (horizontal) x 200 (vertical) pixels. High Resolution images can be created statically from data in a program (such as for games or pictures), or created dynamically during program execution (such as for charts or mathematical effects). Sprite Machine v2.0 illustrates the color limitation when drawing a sprite. On RF display devices (such as televisions), the vertical resolution can be hard to visually define, and a clearer image will be achievable on a composite display device (such as monitors). Whereas High Resolution is the highest graphical standard that the VIC-II can produce, there are output display issues. Notably, a High Resolution output is not necessarily limited by the maximum size of the background area (320 x 200 pixels) as there are techniques which allow composite images into the border area (384 x 272 pixels). Here you can find almost anything which was ever made for the commodore 64, and more is being added every day. Table 1 shows a comparison of resolutions. CSDb (Commodore 64 Scene Database) is a website which goal is to gather as much information and material about the scene around the commodore 64 computer - the worlds most popular home computer throughout time. In reality, CPU clock cycles prevent a 1:1 PAR accuracy but is a fair approximation for this description and helps to contrast against other resolutions on the C64. It has a theoretical Pixel Aspect Ratio (PAR) of 1:1 with 64 elements in an 8 x 8 pixel character location. High Resolution is defined as the maximum pixel density which the VIC-II can produce in a given screen area. ![]()
