This project aims to port the fpgaNES NES emulator (https://github.com/strigeus/fpganes) to the Xilinx KR260 FPGA. The fpgaNES emulator allows you to play NES games on FPGA hardware.
To recreate the project in Vivado, follow these steps:
- Open Vivado and navigate to the "project" folder.
- Launch Vivado and run the command "source project.tcl".
Once the project is compiled in Vivado, you can load the bitstream onto the KR260 FPGA by following these commands in XSCT (Xilinx Software Command-line Tool) in sequence:
- Connect
- targets -set -nocase -filter {name =~ "*PSU*"}
- mwr 0xff5e0200 0x0100
- rst -system
Then, via Vivado, click on "Program device".
The project directory has the following structure:
project: contains the TCL project file for recreating the project.sources: contains the project sources.tools: contains scripts for converting a NES ROM file to COE format for loading the ROM into the Cartridge IP.
To load a new NES cartridge, generate the COE file and load it via Vivado interface. Follow these steps:
- Generate the COE file using the provided tools/scripts.
- Load the COE file in Vivado in the ip called Cartridge.
For VGA output, you can use a PMOD VGA adapter. We recommend using this PMOD VGA adapter by Digilent. Connect the PMOD VGA adapter to the PMOD 3-4 ports.
The audio output is mapped on PMOD 2 on pin 1 (left channel) and pin 2 (right channel).
