, the goal is to automate the exploit so you don't have to manually plug and unplug a USB drive.
On standard Switch firmware 5.1.0 (the sweet spot for this exploit), the ExFAT driver trusts the device. Because the Pico is acting as a physical USB drive, the Switch does not cache the partition data as aggressively as it does with an internal SD card slot. This results in a success rate jump from roughly 8% (standard method) to (Pico exclusive).
Hold the BOOTSEL button on the Pico, plug it into your PC. Drag and drop the exfathax_pico_exclusive.uf2 file onto the RPI-RP2 drive. The Pico will reboot.
If you already own a Raspberry Pi Pico from a previous project (like a Picofly or a keyboard project), this is a fun weekend exploit to tinker with. If you don't, is it worth buying one for this specific "exclusive" exploit?
