![]() ![]() The AGA chipset was the first real improvement over the original chipset.įurther screen modes where added, the color palette was extended to 24bit and resolutions with up to 256 colors.Īll resolutions could now be used with all color modes. The reason for this was possibly the attempt to squeeze addition features out of the original chip set design without changing to much on the chip.ĪGA (Advanced Graphics Architecture - released 1992) Technical limitations also limited the usefulness of many of these new modes as most had either very extreme pixel aspect ratios or were limited to very few colors. The first five bitplanes index 32 colors selected from a 12-bit color space (4096 possible colors). New screen modes were added to support higher resolutions offered by multisync monitors but at the same time sacrificing color depth. Extra Half-Brite 64 color mode picture Extra Half-Brite 1 2 (EHB) mode is a planar display mode of the Commodore Amiga computer. The enhanced chip set was released with several small improvements over the original chip set. This also meant that the screen modes varied depending on what type of Amiga you had and where you had it. The hardware that was used in the first generation of Amigas still very close to the original concept of the Amiga being used as a video games console.įor that reason the screen modes were tied very closely to the television standards NTSC and PAL that were in use at that time. In reality PAL pixels are a tiny bit wider than they are tall (16:15) and NTSC pixels are a bit taller than they are wide (8:9). The ratios in the lists are pixel aspect ratios and the are rounded to the nearest neighbour. Also, some 8362 R5 chips (in developer/demo machines only), the HAM mode may not have been tested.The Amiga was capable of displaying various screen resolutions.Īll monitors and TV's of that time had a picture aspect ratio of 4:3 but the pixel aspect ratio varied greately. * No Extra Half Bright mode in only this version. The 32 colors per palette is a hardware limitation for the pre-AGA chipsets. ![]() Denise is the ECS & OCS chipset equivalent of Lisa, found in the AGA chipset. Extra Half Brite (EHB) mode is a screenmode of the Commodore Amiga computer. Some versions of Denise (usually those in the ECS chipset) also support EHB mode (extra half-brite) which is up to 64 colours on screen, however the second 32 colours MUST be half the brightness of the first 32. It uses a customized version of the CDXL format supporting the AGA chipset with 24 bit colors. It supports up to 32 colours per screen from a palette of 4096, or 4096 colours on screen in HAM-6 mode. AGABlaster is a video player for the Amiga Commodore computer. The Denise is responsible for handling most of the graphics related tasks, including the native screens and support for up to eight hardware sprites. ![]()
