Electron has announced, that his work on new Atari invention: Video Board XE is to be finished soon. The idea is based on the GTIA replacement with a new chip. As a result we've got:
- GTIA compatibility - only old PMG and so called GTIA modes don't work.
- Sprite blitter with it's own 512 KB of RAM. It generates sprites with sizes from 1x1 to 256x256 points in the resolution of 320x192, each sprite in 256 colors. Number of sprites is limited only with blitter effectiveness, at least it wil be 30 pieces with 32x32 size and 256 colors per frame.
- Programmable priorities for sprites and background. Simple sprite collision detection.
- Programmable x and y sprite positions with 1 hi-res pixel presision.
- Two programmable 256 color palettes - one for the playfield and one for sprites. The palette colors are chosen from the 65536 colors (Hi-Color RGB).
- Playfield colors map in 8x8 and 4x4 pixels resolution, for each such block a 1 of 32 color-sets may be chosen (all playfield colors are changed), it is also possible to scroll color map vertically/horizontally with 1 pixel precision.
- Ability to mix hi-res and color modes with appropriate definitions in the map of colors..
- RGB output for monitor/TV.
