Nintendo’s Switch 2 was originally designed to only support the microSD Express extension, but now someone has directly “hardwired” the M.2 SSD, and the system really recognizes it! A Japanese expert demonstrated a homemade PCB adapter solution that plugged a 512GB M.2 NVMe SSD into the microSD Express slot, and the host not only reported no errors, but also directly displayed additional capacity in the system. The point is, the main unit has not been rebuilt, and the system still recognizes it!
It’s not a simulation, it’s not a cracked system, it’s actually being identified as a storage device.
It’s not about transferring, it’s about “tricking the system”
The most core breakthrough this time is not simply to connect the interface, but to solve the initialization and verification process of Switch 2.
In the past, some people have tried to connect the microSD Express directly to the M.2 SSD, but it will be stuck in the system detection phase, because the host expects a “memory card”, not an SSD. This time, he left a microSD Express card on the adapter board to trick the system, and then let the M.2 SSD be responsible for the actual storage, not the hard connection succeeded, but “let the host think that it is still using the memory card”.
Theory works, but practicality is currently close to zero
Although it looks fierce, this plan has almost no daily use value at this stage. The entire device is an external PCB + cable, and the volume, stability, and power consumption are completely unsuitable for playing with the host. What’s more, the Switch 2 official only intends to let you use microSD Express, which is equivalent to stepping on the edge of the system, and it is likely that the system will break after the update.
But the next question is only one, is there a vendor who can make this kind of solution into a real product?
