The Enterprise has custom video and sound hardware.
The video chip is called "Nick" and it executes a display list. This allows the mode to be redefined every scanline.
The Enterprise has a variety of bitmap modes, ranging from cell based bitmap modes similar to the Spectrum, to bitmapped modes like the CPC. It also supports hardware text mode, and 256 colors (8 levels of red * 8 levels of green * 4 levels of blue).</br>
Therefore converting graphics and code from either platform was easy, although mode 0 of the CPC was made somewhat more difficult by the fact that only the first 8 colors of the palette can be chosen freely, while the second 8 colors are generated by using the lower 3 bits of the color index as the most significant bit of the red, green, and blue components, and the remaining 5 bits are added from a "fixbias" register. For this reason, a 16-color CPC conversion usually needs to find a good "fixbias" value, and convert all pixel data to the changed order of colors in the Enterprise palette. In the case of Spectrum conversions, it was also necessary to convert the attribute data.

The sound chip is called "Dave" and has 3 channels of sound (square wave or noise), and a fourth channel that can only generate noise; it also has 6-bit stereo volume control for all channels, simple (digital) filters, ring modulation, various noise waveforms, has a selection of interrupts and can play samples easily.

The fact it could mix Character attribute system or Amstrad like Graphic modes, with a greater freedom, means it could easily benefit from both Softwares Library with a bit of hacking.
