Pokémon Mini Gets New MicroSD Flash Cartridge Through PM2354 SD Kickstarter Campaign
Crowdfunding opens for the PM2354 SD, an RP2040-Zero flash cartridge allowing MicroSD game loading and Game Boy ROM support on original Pokémon Mini hardware.
One of Nintendo's smallest and most unusual handheld systems may soon become considerably easier to use with homebrew software and preserved games. A crowdfunding campaign has launched for the PM2354 SD, a MicroSD-based cartridge designed for the Pokémon Mini. Originally released in 2001, the Pokémon Mini was a tiny handheld console built around a collection of relatively simple Pokémon-themed games. Despite its limited commercial lifespan, the machine developed a dedicated community interested in hardware experimentation, homebrew development and software preservation. The new cartridge aims to eliminate some of the inconvenience associated with loading alternative software onto original hardware. Existing programmable cartridges can require external programming equipment and generally store one game at a time. The PM2354 SD instead uses a MicroSD card, allowing compatible software to be stored and selected without repeatedly rewriting the cartridge. According to the project's developers, a working prototype already exists and can run Pokémon Mini software as well as original Game Boy ROMs through supported functionality. The design draws inspiration from earlier open-source work associated with zwenergy's PM2040 project, although the teams are not formally affiliated. Hardware development uses a Waveshare RP2040-Zero microcontroller platform. The crowdfunding price is approximately $60 before shipping, with the organisers targeting delivery before the end of 2026. However, that schedule remains an estimate, and crowdfunding participation does not guarantee successful manufacturing or delivery. The cartridge could become a useful accessory for collectors interested in translations, homebrew and preservation projects on genuine Pokémon Mini hardware. Nintendo originally designed the machine to fit comfortably into a pocket. Modern enthusiasts are now attempting to fit an entire software collection into its cartridge slot.
