Attila has released a modification to Firmware Downgrader 1.1, now calling it Firmware Downgrader v1.21 mod. This tool can downgrade you’re system menu, although t is NOT recommended to do so anymore!
Changes:
– An audit of Boot2 whether the downgrade can damage the console.
– A reading of the wad files needed on the SD card to enable downgrade without internet.
– An upgrade from any version
– A change in the region if necessary fully functional.
– A support for the Wiimote and GameCube
