Twenty years after the release of the Nintendo DS, managing the system’s physical media presents an ongoing logistical challenge for users. In my latest retro video, I take a look at the DSPico, an open-source flash cartridge designed to boot digital copies of DS games directly on original hardware. These sell for around $20 on Aliexpress (compensated affiliate link)
The device retails for approximately $20, with shipping bringing the total cost to around $30. It is built around a Raspberry Pi RP2040 microcontroller and features a USB-C port alongside an SD card slot. The pre-assembled model I examined shipped with an 8-gigabyte SD card. The hardware requires a FAT32 format, and while some users have reported software lockups when using larger 64-gigabyte and 128-gigabyte cards, developers are currently addressing these bugs through firmware updates on GitHub. Updating the firmware requires connecting the cartridge to a computer via USB-C and transferring the necessary files to the card.
The cartridge has full access to the SD card, so you can store ROM files in an organizational structure of your choice. The DSPico reads and writes save files to the SD card and saves function just like they do on a regular cartridge. But it does not support save states like some Gameboy cartridges do.
The DSpico is compatible with the original DS, the DS Lite, the DSi, and the 3DS line. It only runs standard DS software, meaning it cannot be used to load 3DS-specific titles. On compatible hardware like the DSi and the 3DS, the DSPico also supports DSiware titles that were originally distributed strictly over the Internet – currently the only flash cart to do so.
Beyond preservation of out of print games, the DSPico serves as a loader for homebrew projects. I tested a few community projects, including a 3D role-playing game currently in development called WolveSlayer and a port of Lemmings. Both games played without issues. LemmingsDS goes beyond just a ROM file and utilizes a process where secondary assets are pulled directly from the SD card after the initial ROM loads.
As the secondary market for physical DS cartridges continues to experience price inflation, the DS Pico presents a functional method for accessing older software libraries without requiring the original media. Because the entire project is open-source, individuals have the choice to assemble the hardware themselves using the public repository or purchase pre-manufactured units from existing suppliers. The active development surrounding the device suggests that this two-decade-old handheld platform will remain accessible for the foreseeable future.
