Description

This project is a port of the 1chipMSX to DEOCM + DE0-CV including modification of OCM-PLD.

How to install

1. Register and SignIn for Intel FPGA Program.
2. Download and install 'Additional Software>Quartus Prime Programmer and Tools'.
3. Download and unzip pof file from deocm-pld-cv Releases.
4. Connect your PC and DE0-CV with USB cable.
5. Set the RUN/PROG slide switch (SW10) of DE0-CV to the PROG position.
6. Run 'Quartus Prime Programmer and Tools' and write pof file to flash memory(EPCS) on DE0-CV.
7. Set the RUN/PROG slide switch (SW10) of DE0-CV to the RUN position.
