Based on Gregory Estrade's Work.

I have ported the PC Engine System to DE0-NANO, why don't you have a look?

I made some changes:

Booting the PCengine from EPCS memory instead of a flash memory of DE1 or DE2-115.
Audio works with Delta Sigma instead of WM8731 codec, ideal for the DE0-NANO.
Here you go the DE0-NANO Sources
- Here you go the PCB Design.

Connect the DE0-NANO using your USB to power it on.

Click on "Open", select "Open USB Port 0".

Select the "EPCS" tab, and click on "Chip Erase".

Check "File Length", then click on "Write a File to EPCS".

Choose a PC-Engine ROM.

Once the write operation is done, close the "DE0-NANO Control Panel".

The switches(SW[3:1]) depend on the type of pceeng image.

- SW1 : header present or not (usually, ROMs do have this header, so set it to "1").

- SW2 : set it to "1" if your ROM is 768 Kb.

- SW3 : set it to "1" if you're dealing with a TGFX ROM instead of a PCE ROM.

NEC created a very basic region-lockout by swapping data bits on the cartridge

and cartridge connector on US (TGFX-16) consoles.

So, for the (very few) ROMs that have been dumped off a US cartridge, set it to "1".

If unsure, set it to "0".

Then program the .sof.
