Introduction

A NES (Nintendo Entertainment System) emulator with SD card and menu support for the Raspberry Pi Pico, Raspberry Pi Pico 2 and other RP2040/RP2350 based microcontrollers. Uses HDMI for display.

Supports two controllers for two player games. See "about two player games" below for specifics and limitations

The emulator used is Infones by Jay Kumogata which was ported to the Raspberry Pi Pico by Shuichi Takano with changes done by me to accomodate the SD card menu.

Create a FAT32 formatted SD card and copy your NES roms on to it. It is possible to organize your roms into different folders. Then insert the SD Card into the card slot. Needless to say you must own all the roms you put on the card.

A menu is added to the emulator, which reads the roms from the SD card and shows them on screen for the user to select, flash and play.

See below for possible configurations, supported game controllers and how to setup. There is even a custom PCB (printed circuit board) available and a 3D-printable case design which fits the PCB.

See also the Adafruit guide.

There is also an emulator port for the Sega Master System/Sega Game Gear and DMG Game Boy. You can find them here:

Possible configurations

You can use it with these RP2040/RP2350 boards and configurations:

See below to see how to setup your specific configuration.

Note

It seems that sellers on AliExpress have copied the PCB design and are selling pre-populated PCB's. I do not condone this in any way. For questions about those boards, please contact the seller on AliExpress.

Gamecontroller support

Depending on the hardware configuration, the emulator supports these gamecontrollers:

USB Controllers

  • Sony Dual Shock 4
  • Sony Dual Sense
  • BUFFALO BGC-FC801 connected to USB - not tested
  • Genesis Mini 1 and 2
  • PlayStation Classic
  • Keyboard
  • XInput type of controllers like Xbox 360 and Xbox One controllers and other XInput compatible controllers like 8bitDo.
  • Mantapad, cheap NES and SNES USB controllers from AliExpress.

See also troubleshooting USB controllers below

Note

There is some input lag when using USB controllers.

Legacy controllers

  • One or optional two original NES controllers for two player games. In some configurations, soldering is required.
  • WII-classic controller: Adafruit Feather RP2040 and WaveShare RP2040 Pi-Zero boards only

Parts list for legacy controllers

About two player games

The emulator supports two player games using two NES controllers or an USB gamecontroller and a NES controller.

Note

You cannot use two USB controllers for two player games. At the moment only one USB controller is recognized by the driver. In this case the USB controller is always player 1. Player 2 must be a NES controller.

Player 1 Player 2
USB controller connected USB NES port 1 or NES port 2
No usb controller connected NES port 1 NES port 2

Warning

Repeatedly flashing your Pico will eventually wear out the flash memory.

The emulator overclocks the Pico in order to get the emulator working fast enough. Overclocking can reduce the Pico's lifespan.

Use this software at your own risk! I will not be responsible in any way for any damage to your Pico and/or connected peripherals caused by using this software.

I also do not take responsability in any way when damage is caused to the Pico or display due to incorrect wiring or voltages.

Setup

Click on the link below for your specific board configuration:

Raspberry Pi Pico or Pico 2, setup for Pimoroni Pico DV Demo Base.

Waveshare RP2040-PiZero Development Board

materials needed

Note

The PIO-USB cannot be used to connect the USB controller because DVI and PIO-USB cannot be used simultaneously. See productpage Therefore, connect the controller and the power adapter to the Y-cable, and then connect the Y-cable to the port on the board labeled "USB." While the PIO-USB can be used to power the board, I don't recommend this due to occasional strange behavior it has caused.

NES controller port.

When using a original NES controller you need:

For two player games with two NES controllers you need an extra NES controller port, controller and wire

Several Companies can make these PCBs for you.

I personally recommend PCBWay. The boards i ordered from them are of excellent quality. They have also a very short lead time. Boards i ordered on Monday arrived from China to my home in the Netherlands on Friday of the same week.

Image

When ordering, simply upload the zip file containing the gerber design. This file (pico_nesPCB_v2.1.zip) is available in the releases page and can also be found in the PCB folder.

Note

Soldering skills are required. Make sure you solder all the connections from the Pico onto the PCB. Also the connections on the short right-side of the Pico. (For ground)

Note

If you are looking for the previous design (v0.2). You can find it here

Note

It seems that sellers on AliExpress have copied the PCB design and are selling pre-populated PCB's. I do not condone this in any way. For questions about those boards, please contact the seller on AliExpress.

Other materials needed:

When using a Pico, Flash piconesPlusAdaFruitDVISD.uf2 from the releases page. When using a Pico 2 flash pico2_piconesPlusAdaFruitDVISD.uf2 instead.

3D printed case for PCB

Gavin Knight (DynaMight1124) designed a NES-like case you can 3d-print as an enclosure for this pcb. You can find it here: https://www.thingiverse.com/thing:6689537. Here you can find two designs: the latest design for PCB v2.0 and the previous design for PCB v0.2. In the latest v2.0 design, you can choose between two top covers, one with a button connecting to the bootsel button for easy firmware upgrades, the other without the button. In this case you have to remove the top cover to access the bootsel button. See images below. Make sure to print the correct files for the PCB version you own. You can find more information on Gavin's Thingiverse page.

Gamepad and keyboard usage

Menu Usage

Gamepad buttons:

  • UP/DOWN: Next/previous item in the menu.
  • LEFT/RIGHT: next/previous page.
  • A (Circle): Open folder/flash and start game.
  • B (X): Back to parent folder.
  • START: Starts game currently loaded in flash.

The colors in the menu can be changed and saved:

  • Select + Up/Down changes the foreground color.
  • Select + Left/Right changes the background color.
  • Select + A saves the colors. Screen will flicker when saved.
  • Select + B resets the colors to default. (Black on white)

When using an USB-Keyboard:

  • Cursor keys: Up, Down, left, right
  • Z: Back to parent folder
  • X: Open Folder/flash and start a game
  • S: Starts game currently loaded in flash.
  • A: acts as the select button.

Emulator (in game)

Gamepad buttons:

  • SELECT + START, Xbox button: Resets back to the SD Card menu. Game saves are saved to the SD card.
  • SELECT + UP/SELECT + DOWN: switches screen modes.
  • SELECT + A/B: toggle rapid-fire.
  • START + A : Toggle framerate display

When using a Genesis Mini controller, press C for SELECT.

When using an USB-Keyboard

  • Cursor keys: up, down, left, right
  • A: Select
  • S: Start
  • Z: B
  • X: A

Note

The standard NES style layout is used for all controller types. So when using XInput controllers, B and A are swapped.

Save games

For games which support it, saves will be stored in the /SAVES folder of the SD card. Caution: the save ram will only be saved back to the SD card when quitting the game via (START + SELECT)

Raspberry Pico W support

The emulator works with the Pico W, but without the onboard blinking led. In order for the led to work on the Pico W, the cyw43 driver needs to be initialised. This causes the emulator to stop with an out of memory panic.

USB game Controllers latency

Using a USB gamecontroller introduces some latency. The legacy controllers ((S)NES, WII-classic) have less latency.

Troubleshooting usb controllers

AliExpress Controllers (Mantapad)

When starting a game, and the controller is unresponsive, you have to unplug and replug the controller to get it working. Not all controllers behave this way. I have a SNES controller that has no problems. The NES controller however must alwas be replugged to make it work. It is kind of a hit and miss.

XInput style controllers.

Might not work with all controllers.

Tested devices:

  • Xbox 360 : Works
  • Xbox Series X controller : Works
  • Xbox One controller : Works
  • Xbox elite controller : Works
  • 8bitdo SN30 Pro+ firmware V6.01: Works. With the controller switched off, hold X + Start to switch to XInput mode. (LED 1 and 2 will blink). Then connect to USB.
  • 8bitdo Pro 2 firmware V3.04: Works. With the controller switched off, hold X + Start to switch to XInput mode. (LED 1 and 2 will blink). Then connect to USB.
  • 8bitdo SN30 PRO Wired : Not working, recognized but no report
  • 8bitdo SF30 PRO firmware v2.05 : Works. With the controller switched off, hold X + Start to switch to XInput mode. (LED 1 and 2 will blink). Then connect to USB.
  • 8bitdo SN30 PRO firmware v2.05 : Not tested, should probably work

Troubleshooting:

After flashing some bigger games, the controller might become unresponsive:

  • Xbox Controller. Playing with batteries removed is recommended. When controller becomes unresponsive:

    • unplug and replug the controller.
    • If controller is still unresponsive, unplug the pico from power, wait a few seconds then plug it back in and press start to start the last flashed game.

  • 8bitdo controllers, when controller becomes unresponsive:

    • Disconnect the controller.
    • Hold start to switch the controller off (if it has built-in battery).
    • reconnect the controller.

Troubleshooting no image on TV or monitor

  • Make sure the board is directly connected to your display. Do not connect through a HDMI splitter.
  • Some displays need 5V in order to work:
    • When using the breadboard with HDMI and SD breakout, make sure VBUS (Pin 40) is connected to the 5 volt via on the board. (Marked 5 on the side)

Image

Known Issues and limitations

  • Pimoroni Pico DV:
    • Audio through the audio out jack is not supported, audio only works over hdmi.
    • Debug printf statements over UART (GPIO0 and GPIO1) are disabled because GPIO1 is used for second nes controller port.
  • Due to the Pico's memory limitations, not all games will work. Games not working will show a "Mapper n is unsupported." (n is a number). For example starting Castlevania III will show the "Mapper 5 is unsupported." message.
  • tar file support is removed.
  • Pico W: The onboard led does not blink every 60 frames.

Building from source

Best is to use the included build script buildAll.sh. You can then copy the correct .uf2 to your Pico via the bootsel option. The script builds all the .uf2 files and puts them in the releases folder.

git clone https://github.com/fhoedemakers/pico-infonesPlus.git
cd pico-infonesPlus
git submodule update --init
chmod +x build*.sh
./buildAll.sh

Alternatively, you can use the bld.sh shell script:

Build script for the pico-InfoNESPlus project

Usage: ./bld.sh [-d] [-2 | -r] [-t path to toolchain] [-c <hwconfig>]
Options:
  -d: build in DEBUG configuration
  -2: build for Pico 2 board (RP2350)
  -r: build for Pico 2 board (RP2350) with riscv core
  -t <path to toolchain>: only needed for riscv, specify the path to the riscv toolchain bin folder
  -c <hwconfig>: specify the hardware configuration
     1: Pimoroni Pico DV Demo Base (Default)
     2: Breadboard with Adafruit AdaFruit DVI Breakout Board and AdaFruit MicroSD card breakout board
        Custom pcb
     3: Adafruit Feather RP2040 DVI
     4: Waveshare RP2040-PiZero
     hwconfig 3 and 4 are RP2040-based boards, so they cannot be built for Pico 2
