Judging by how many units Nintendo has sold of their latest system, it’s clearly a winning combination. The wireless controllers even pop off the sides so you can kick back on the couch and enjoy your big-screen gaming from a distance. The whole idea behind the Nintendo Switch is that the system isn’t just a handheld, but can be converted into a more traditional home game console when placed into its dock.

Perhaps you can use Pokemon Transporter to transport your pokemon safely from the SRAM to the FRAM. Since you’re replacing the chip, you will lose the data if you haven’t already. Overall, a clever and easy to have to preserve your Pokemon properly. For stability, added a 10k pull-up on the inverted CE (chip enable) pin to make sure the FRAM is disabled when not in use. While FRAM data will only last 10 years, it is a write-after-read process so as long as you load your save file every 10 years, you can keep your Pokemon going for decades. The magic that makes it work is a FRAM (ferroelectric random access memory) made by Cypress that is pin-compatible with the 256K SRAM (made by SK Hynix) on the original game cartridge PCB.

decided to ditch the battery and swap the SRAM for a proper NVRAM on a Pokemon Yellow cartridge, 23 years later. These coin cells last 10-15 years, and many of the Pokemon games came out 20 years ago. Generally, Pokemon games before the GameBoy Advance era had SRAM and a small coin cell to save state as NVRAM (Non-volatile random access memory) was more expensive. The precious Pokemon we spent hours capturing in the early nineties remain trapped, not just by pokeballs, but within a cartridge ravaged by time.
