# SNK M68000 (Ikari III) FPGA Implementation
|
||||
|
||||
FPGA compatible core of SNK M68000 (Ikari III based) arcade hardware originally written by [**Darren Olafson**](https://twitter.com/Darren__O). FPGA implementation has been verified against schematics for Ikari III (A7007). PCB measurements taken from Datsugoku: Prisoners of War (A7008), Street Smart (A8007), and Ikari III: The Rescue (A7007).
|
||||
|
||||
Ikari III PCB donated by [**atrac17**](https://github.com/atrac17) / [**DJ Hard Rich**](https://twitter.com/djhardrich) and verified by [**Darren Olafson**](https://twitter.com/Darren__O). Other SNK68K PCB verification done by [**atrac17**](https://github.com/atrac17). The intent is for this core to be a 1:1 playable implementation of SNK M68000 (Ikari III) arcade hardware. Currently in **beta state**, this core is in active development with assistance from [**atrac17**](https://github.com/atrac17).
