This core is a RW-FPGA dev team project implemented by Ricardo Martinez (KYP) initially in ZXUno. A port to Altera has been made, covering the boards, MiST, MiSTica, SiDi and MiSTer by KYP and rampa069. This core has been designed from scratch.
The Colour Genie was released in 1982. It was an attractive machine, with a solid full-stroke keyboard and 16K BASIC in ROM. As well as the 63-key typewriter keyboard and powerful BASIC, it featured the trusty Z-80, running at 2.2 MHz, 16k-32k of RAM, 3 channels of sound, 8 colours (4 for text), 40 columns x 24 rows for text (initially) and 160 x 102 pixels for graphics.Ports which included RS-232, Joysticks (2), light pen, RGB and audio.
