The original USB Tool scripts, media and license are unchanged. This snapshot updates compatibility documentation for firmware 0.9.1, including ABI6-NP1 with ABI4/5 app support and signed SD UPDATE/RESCUE packages for PCB V1.0 and V1.1.
Keep the microSD directory layout described in the README. Scripts run only after selection and RUN on the device. They are separate from .ekapp Apps packages and contain no game source or app saves.
Compatible signed firmware updates preserve keys, PIN, settings, apps and saves. Initial installation, custom signing keys and matching bootloaders use the firmware's separate EvilKey.cmd workflow before protection is activated. After irreversible Secure Boot activation, only compatible firmware signed by the enrolled key is accepted. Example scripts do not change firmware trust or activate HMAC/Secure Boot.
