fastCFWswitch

A tesla based overlay to boot into different payloads on the Nintendo Switch.

Supported devices

Only Switch consoles with the old Erista SOC are supported, because exosphere uses a bootrom exploit to reboot to a payload.

• Setup the tesla menu and nx-ovlloader
• Extract the latest release to the sd card
• Modify the configuration in /config/fastCFWSwitch/config.ini
