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.
There is also an emulator port for the Sega Master System/Sega Game Gear and DMG Game Boy. You can find them here:
- Sega Master System/Game Gear: https://github.com/fhoedemakers/pico-smsplus
- DMG Game Boy: https://github.com/fhoedemakers/pico-peanutGB

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 |
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.

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.
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.

The emulator works with the Pico W (RP2040). Use the pico_w_ versions of the uf2 files in the latest release. The Pico W has a built-in wifi module. The wifi module is not used by the emulator. It is only used for enabling the led to blink every 60 frames on the Pico W. If you don't mind the led blinking, you can use the pico_ versions of the uf2 files on the Pico W.
Although you can build them yourself, there are no pico2_w .uf2 binaries for the Pico2 W (RP2350) in the latest release, use the pico2_ versions instead. There are issues with the display on the Pico2 W when blinking the led. Also ioctl timeout errors are printed on the uart console.
Using a USB gamecontroller introduces some latency. The legacy controllers ((S)NES, WII-classic) have less latency.
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.
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
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.
- 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)
- 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.
- Pico2 W: Blinking the onboard led causes display issues and ioctl timeout errors on the uart console.
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.shAlternatively, you can use the bld.sh shell script:
