Summary
- An SNES owner has developed a replacement for the console’s CPU based on an FPGA.
- The FPGA is both affordable and available, and has sufficient logical cells to be a suitable replacement.
- The project is based on the SNESTANG FPGA, which provided the core functionality of the CPU replacement.
- Two flexible PCBs connect the FPGA to the SNES hardware, via a connector with enough pins to support the required functionality.
- This is not the first time FPGAs have been used to replace components in legacy hardware, and the team welcome stories from other projects.
