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.
Port to MiSTer by alanswx, CAS tape support by Flandango.
